  • Some jQuery-powered features not working in Chrome

    - by Enchantner
    I'm using a jCarouselLite plugin for creating two image galleries on the main page of my Django-powered site. The code of elements with navigation arrows is generating dynamically like this: $(document).ready(function () { $('[jq\\:corner]').each(function(index, item) { item = $(item); item.corner(item.attr('jq:corner')) }) $('[jq\\:menu]').each(function (index, item) { item = $(item); item.menu(item.attr('jq:menu')) }) $('[jq\\:carousel]').each(function(index, item) { item = $(item); var args = item.attr('jq:carousel').split(/\s+/) lister = item.parent().attr('class') + '_lister' item.parent().append('<div id="'+ lister +'"></div>'); $('#' + lister).append("<a class='nav left' href='#'></a><a class='nav right' href='#'></a>"); toparrow = $(item).position().top + $(item).height() - 50; widtharrow = $(item).width(); $('#' + lister).css({ 'display': 'inline-block', 'z-index': 10, 'position': 'absolute', 'margin-left': '-22px', 'top': toparrow, 'width': widtharrow }) $('#' + lister + ' .nav.right').css({ 'margin-left': $('#' + lister).width() + 22 }) item.jCarouselLite({ btnNext: '#' + lister + ' .nav.right', btnPrev: '#' + lister + ' .nav.left', visible: parseInt(args[0]) }) }) The problem is that if page is loaded through an url, typed in the adress bar, some functions doesn't work and the second gallery appears with the wrong parameters, but if I came to this page via clicking link - everything works perfectly. It happends only in Google Chrome (Ubuntu, stable 5.0.360.0), but not in Firefox or Opera. What could be the reason?

  • Increasing Regex Efficiency

    - by cam
    I have about 100k Outlook mail items that have about 500-600 chars per Body. I have a list of 580 keywords that must search through each body, then append the words at the bottom. I believe I've increased the efficiency of the majority of the function, but it still takes a lot of time. Even for 100 emails it takes about 4 seconds. I run two functions for each keyword list (290 keywords each list). public List<string> Keyword_Search(HtmlNode nSearch) { var wordFound = new List<string>(); foreach (string currWord in _keywordList) { bool isMatch = Regex.IsMatch(nSearch.InnerHtml, "\\b" + @currWord + "\\b", RegexOptions.IgnoreCase); if (isMatch) { wordFound.Add(currWord); } } return wordFound; } Is there anyway I can increase the efficiency of this function? The other thing that might be slowing it down is that I use HTML Agility Pack to navigate through some nodes and pull out the body (nSearch.InnerHtml). The _keywordList is a List item, and not an array.

  • VBA compare and sort strings with quirky characters

    - by Smandoli
    I am comparing text values from two DAO recordsets in MS Access. I sort on the text field, then go through both recordsets comparing the values from each. The sets are substantially different and while they're mostly alpha-numeric, spaces and symbols like hyphens and periods are very common. My program depends on predictable sorting and fool-proof comparing. But unfortunately, the sort will rank two values differently than the comparison function. StrComp is the obvious first choice: varResult = StrComp(Val_1, Val_2) RFA-300 14.9044 RFA300 14-2044 But for the two pairs above, StrComp returns a different value than one would expect based on the sort. Including vbTextCompare or vbBinaryCompare affects StrComp's result, but not so as to solve the problem. Note the values must always be compared as strings. Of course I make sure that "14-2044" and "14.9044" aren't evaluated as -2030 and ~15. That's not the cause of my problem. I learned API-based functions are more reliable for quirky texts, so I tried these: varResult = CompareString(LOCALE_SYSTEM_DEFAULT, _ SORT_STRINGSORT, strVal_2, -1, strVal_1, -1) varResult = CompareString(LOCALE_SYSTEM_DEFAULT, _ NORM_IGNOREWIDTH, strVal_2, -1, strVal_1, -1) The first one returns the opposite of StrComp. The second one returns the same as StrComp. But neither yields a result that is consistent with the sort order. (NORM_IGNOREWIDTH is probably not relevant, but I needed a place-holder substitute and it looked as good as any.) UPDATE: This is a complete rewrite of the original post, deleting all the info about why I really need this -- just take my word for it and enjoy the brevity.

  • PHP Session data not being saved

    - by Crackerjack
    I have one of those "I swear I didn't touch the server" situations. I honestly didn't touch any of the php scripts. The problem I am having is that php data is not being saved across different pages or page refreshes. I know a new session is being created correctly because I can set a session variable (e.g. $_SESSION['foo'] = "foo" and print it back out on the same page just fine. But when I try to use that same variable on another page it is not set! Is there any php functions or information I can use on my hosts server to see what is going on? Here is an example script that does not work on my hosts' server as of right now: <?php session_start(); if(isset($_SESSION['views'])) $_SESSION['views'] = $_SESSION['views']+ 1; else $_SESSION['views'] = 1; echo "views = ". $_SESSION['views']; echo '<p><a href="page1.php">Refresh</a></p>'; ?> The 'views' variable never gets incremented after doing a page refresh. I'm thinking this is a problem on their side, but I wanted to make sure I'm not a complete idiot first. Here is the phpinfo() for my hosts' server (PHP Version 4.4.7):

  • Complete failure to compile when include CSS Friendly Adapters

    - by david
    Background - I am trying to use the friendly adapters to override the default styling for the standard asp.net menu control that is used by an existing project. The existing project functions normally and compiles when requested without incident. Adding in the code for the for the CSS Friendly adapter and not only does it not compile, but it never even really starts. The Problem in Detail - I am using the sample code from Scott on this page: http://weblogs.asp.net/scottgu/archive/2006/09/08/CSS-Control-Adapter-Toolkit-Update.aspx. The sample project compiles fine, just within the existing project does it fail. Fails without a line number or any other traceable info. It definately appears to be related to the CSSMenuAdapter.browser file, which has been referenced by others online as the cause of similar error. I have tried addind and readding, using as a dll, using as a code file in app code, etc. I am working with aspdotnetstorefront in this case, although it is not unique to them as I have found other references in software packages online. Only thing is, no one ever says what solved the issue. I am using Windows 7, VS2008 Express and SQL Express 2008 R2. The full error msg is: Error 10 Exception of type 'System.OutOfMemoryException' was thrown. Notice that there is no file, line, or column info. Really need some help here. I have been working on this a long time. This really should have tag: cssfriendlyadapter but I could not create that.

  • Memory Leaks when touching UITableViewCells and poping off view.

    - by Falcon
    Hi All, I'm currently having a problem where the leaks tool is reporting a slew of memory leaks after clicking on cells within a UITableView and then hitting the back button and popping off the view. Majority of the leaks reported can not be traced back to any specific location in my code, they are: Leaked Object # Address Size Responsible Library Responsible Frame NSCFArray 2 < multiple > 64 UIKit -[UITouch(UITouchInternal) UITouch 2 < multiple > 128 GraphicsServices PurpleEventCallback Malloc 48 Bytes 2 < multiple > 96 Foundation -[NSCFArray insertObject:atIndex:] UIDelayedAction 2 < multiple > 96 UIKit -[UILongPressGestureRecognizer startTimer] NSCFArray 2 < multiple > 64 UIKit -[UILongPressGestureRecognizer touchesBegan:withEvent:] Malloc 32 Bytes 2 < multiple > 64 Foundation -[NSCFArray insertObject:atIndex:] Malloc 16 Bytes 2 < multiple > 32 Foundation -[NSCFSet unionSet:] Now I have commented out all my code in any touch event functions that I have written and it still leaks if I click on the cell a few times and then hit the back button to return to the previous view. Any ideas on what might actually be the problem here? Thanks,

  • VS2010 : javascript intellisense : specifying properties for 'options' objects passed to methods

    - by Master Morality
    Since javascript intellisense actually seems to work in VS2010, I thought I might add some to those scripts I include in almost everything. The trouble is, on some complex functions, I use option objects instead of passing umpteen different parameters, like so: function myFunc(options){ var myVar1 = options.myVar1, myVar2 = options.myVar2, myVar3 = options.myVar3; ... } the trouble I am running into is, there doesn't seem to be a way to specify what properties options needs to have. I've tried this: function myFunc(options){ ///<summary>my func does stuff...</summary> ///<param name="options"> ///myVar1 : the first var ///myVar2 : the second var ///myVar3 : the third var ///</param> var myVar1 = options.myVar1, myVar2 = options.myVar2, myVar3 = options.myVar3; ... } but the line breaks are removed and all the property comments run together, making them stupidly hard to read. I've tried the <para> tags, but to no avail. If anyone has any ideas on how I might achieve this, please let me know. -Brandon

  • How to use javascript class from within document ready

    - by Richard
    Hi, I have this countdown script wrapped as an object located in a separate file Then when I want to setup a counter, the timeout function in the countdown class can not find the object again that I have setup within the document ready. I sort of get that everything that is setup in the document ready is convined to that scope, however it is possible to call functions within other document ready´s. Does anyone has a solution on how I could setup multiple counters slash objects. Or do those basic javascript classes have to become plugins This is some sample code on how the class begins function countdown(obj) { this.obj = obj; this.Div = "clock"; this.BackColor = "white"; this.ForeColor = "black"; this.TargetDate = "12/31/2020 5:00 AM"; this.DisplayFormat = "%%D%% Days, %%H%% Hours, %%M%% Minutes, %%S%% Seconds."; this.CountActive = true; this.DisplayStr; this.Calcage = cd_Calcage; this.CountBack = cd_CountBack; this.Setup = cd_Setup; } thanks, Richard

  • Convert a nested array into a flat array with PHP

    - by Ben Fransen
    Hello all, I'm trying to create a generic database mapping class with PHP. Collecting the data through my functions is going well, but as expected I'm retrieving a nested set. A print_r of my received array looks like: Array ( [table] => Session [columns] => Array ( [0] => `Session`.`ID` AS `Session_ID` [1] => `Session`.`User` AS `Session_User` [2] => `Session`.`SessionID` AS `Session_SessionID` [3] => `Session`.`ExpiresAt` AS `Session_ExpiresAt` [4] => `Session`.`CreatedAt` AS `Session_CreatedAt` [5] => `Session`.`LastActivity` AS `Session_LastActivity` [6] => `Session`.`ClientIP` AS `Session_ClientIP` ) [0] => Array ( [table] => User [columns] => Array ( [0] => `User`.`ID` AS `User_ID` [1] => `User`.`UserName` AS `User_UserName` [2] => `User`.`Password` AS `User_Password` [3] => `User`.`FullName` AS `User_FullName` [4] => `User`.`Address` AS `User_Address` ) [0] => Array ( [table] => Address [columns] => Array ( [0] => `Address`.`ID` AS `Address_ID` [1] => `Address`.`UserID` AS `Address_UserID` [2] => `Address`.`Street` AS `Address_Street` [3] => `Address`.`City` AS `Address_City` ) ) ) ) To simplify things I want to recreate this nested array to a flat array so I can easily loop through it and use the 'columns' key to create my SELECT query. I'm kinda struggling with this for a while now and figures, maybe some users at SO can help me out here. I've tried multiple things with recursion, all without luck so far... Any help is much appriciated! Thanks in advance, Ben Fransen

  • How to Avoid PHP Object Nesting/Creation Limit?

    - by Will Shaver
    I've got a handmade ORM in PHP that seems to be bumping up against an object limit and causing php to crash. Here's a simple script that will cause crashes: <? class Bob { protected $parent; public function Bob($parent) { $this->parent = $parent; } public function __toString() { if($this->parent) return (string) "x " . $this->parent; return "top"; } } $bobs = array(); for($i = 1; $i < 40000; $i++) { $bobs[] = new Bob($bobs[$1 -1]); } ?> Even running this from the command line will cause issues. Some boxes take more than 40,000 objects. I've tried it on Linux/Appache (fail) but my app runs on IIS/FastCGI. On FastCGI this causes the famous "The FastCGI process exited unexpectedly" error. Obviously 20k objects is a bit high, but it crashes with far fewer objects if they have data and nested complexity. Fast CGI isn't the issue - I've tried running it from the command line. I've tried setting the memory to something really high - 6,000MB and to something really low - 24MB. If I set it low enough I'll get the "allocated memory size xxx bytes exhausted" error. I'm thinking that it has to do with the number of functions that are called - some kind of nesting prevention. I didn't think that my ORM's nesting was that complicated but perhaps it is. I've got some pretty clear cases where if I load just ONE more object it dies, but loads in under 3 seconds if it works.

  • Django Image Upload: IOErrno2 Could not find path -- and yet it's saving the image there anyway?

    - by Rob
    I have an issue where the local version of django is handling image upload as expected but my server is not. Note: I am using a Django Container on MediaTemple.net (grid server) Here is my code. def view_settings(request): <snip> if request.POST: success_msgs = () mForm = MainProfileForm(request.POST, request.FILES, instance = mProfile) pForm = ChangePasswordForm(request.POST) eForm = ChangeEmailForm(request.POST) if mForm.is_valid(): m = mForm.save(commit = False) if mForm.cleaned_data['avatar']: m.avatar = upload_photo(request.FILES['avatar'], settings.AVATAR_SAVE_LOCATION) m.save() success_msgs += ('profile pictured updated',) <snip> def upload_photo(data,saveLocation): savePath = os.path.join(settings.MEDIA_ROOT, saveLocation, data.name) destination = open(savePath, 'wb+') for chunk in data.chunks(): destination.write(chunk) destination.close() return os.path.join(saveLocation, data.name) Here's where it gets whacky and I was hoping someone could shed a light on this error, because either a) it's the wrong error code, or b) something is happening with the file before it's completely handled. To recap, the file was actually uploaded to the server in the intended directory - and yet this err msg continues to persist.

  • Hotkey to toggle checkboxes does opposite

    - by Joel Harris
    In this jsFiddle, I have a table with checkboxes in the first column. The master checkbox in the table header functions as expected toggling the state of all the checkboxes in the table when it is clicked. I have set up a hotkey for "shift-x" to toggle the master checkbox. The desired behavior when using the hotkey is: The master checkbox is toggled The child checkboxes each have their checked state set to match the master But what is actually happening is the opposite... The child checkboxes each have their checked state set to match the master The master checkbox is toggled Here is the relevant code $(".master-select").click(function(){ $(this).closest("table").find("tbody .row-select").prop('checked', this.checked); }); function tickAllCheckboxes() { var master = $(".master-select").click(); } //using jquery.hotkeys.js to assign hotkey $(document).bind('keydown', 'shift+x', tickAllCheckboxes); This results in the child checkboxes having the opposite checked state of the master checkbox. Why is that happening? A fix would be nice, but I'm really after an explanation so I can understand what is happening.

  • System.out.println() does not operate in Akka actor

    - by faisal abdulai
    I am kind of baffled by this encointer. I am working an akka project that was created as a maven projecct and imported into eclipse using the mvn eclipse:eclipse command. the akka actor has the system println method just to make it easy to do read the functions and methods invoked. However any time I run the akka system, the println command does not print any thing to the eclipse console but I do not get any error messages. does any one have any idea about this. below is a code snippet. public class MasterActor extends UntypedActor { /** * */ ActorSystem system = ActorSystem.create("container"); ActorRef worker1; //public MasterActor(){} @Override public void onReceive(Object message) throws Exception { System.out.println(" Master Actor 5"); if(message instanceof GesturePoints) { //GesturePoints gp = (GesturePoints) message; System.out.println(" Master Actor 1"); try { worker1.tell(message, getSelf()); System.out.println(" Master Actor 2"); } catch (Exception e) { getSender().tell(new akka.actor.Status.Failure(e), getSelf()); throw e; } } else{ unhandled(message);} } public void preStart() { worker1 = getContext().actorFor("akka://[email protected]:2553/user/workerActor"); } } don't know whether it is a bug in eclipse. thank you.

  • How to do logout functionality in C# smart device application?

    - by Shailesh Jaiswal
    I am developng Smart device application in C#. It is a window application. In this application I am using Login form to authenticate the users. Only authenticated users can login into the system. In this application I am calling java web services which resides on another machine. I am passing mobile number & password from mu application's login form to the java web services. The java web services returns the userid after successful authentication. I made this userid static so that it can be used frequently with other web services.

  • Programmatically disable WiredHeadset

    - by tyrone-tudehope
    Hi, I have an HTC Hero with a major issue. It thinks that the headset/headphones are plugged in. I sent it to HTC and they said there is water damage so no fix. I have tried toggleheadset, toggleheadset2. I've rooted my device and installed the Android 2.1 ROM. Now I found out that AudioManager.setRouting and .setWiredHeadsetOn(bool) have been deprecated and subsequently removed. I read a post somewhere about how you can create a wrapper for the AudioSystem class as the setRouting is still available there. I as of yet have not been able to figure out how to go about doing this as the AudioSystem class is hidden in the SDK and the code makes use of native functions. Does anybody know of a way to go about creating and implementing a wrapper for AudioSystem or of another way to disable the headset? P.S. I've cleaned out the headset port so there is no dust or anything sending false signals to the mainboard. Any help will be greatly appreciated. Thanks, Tyrone

  • How do I add and remove an event listener using a function with parameters?

    - by Bungle
    Sorry if this is a common question, but I couldn't find any answers that seemed pertinent through searching. If I attach an event listener like this: window.addEventListener('scroll', function() { check_pos(box); }, false); it doesn't seem to work to try to remove it later, like this: window.removeEventListener('scroll', function() { check_pos(box); }, false); I assume this is because the addEventListener and removeEventListener methods want a reference to the same function, while I've provided them with anonymous functions, which, while identical in code, are not literally the same. How can I change my code to get the call to removeEventListener to work? The "box" argument refers to the name of an <iframe> that I'm tracking on the screen; that is, I want to be able to subscribe to the scroll event once for each <iframe> that I have (the quantity varies), and once the check_pos() function measures a certain position, it will call another function and also remove the event listener to free up system resources. My hunch is that the solution will involve a closure and/or naming the anonymous function, but I'm not sure exactly what that looks like, and would appreciate a concrete example. Hope that makes sense. Thanks for any help!

  • Vim + OmniCppComplete and completing members of class members

    - by Robert S. Barnes
    I've noticed that I can't seem to complete members of class members using OmniCppComplete. For example, given the following files: // foo.h #include <string> class foo { public: void set_str(const std::string &); std::string get_str_reverse( void ); private: std::string str; }; // foo.cpp #include "foo.h" using std::string; string foo::get_str_reverse ( void ) { string temp; temp.assign(str); reverse(temp.begin(), temp.end()); return temp; } /* ----- end of method foo::get_str ----- */ void foo::set_str ( const string &s ) { str.assign(s); } /* ----- end of method foo::set_str ----- */ I've set up tags for stdlibc++ and generated the tags for these two files using: ctags -R --c++-kinds=+pl --fields=+iaS --extra=+q . When I type temp. in the cpp I get a list of string member functions as expected. But if I type str. omnicomplete spits out "Pattern Not Found". I've noticed that the temp. completion only works if I have the using std::string; declaration. How do I get completion to work on my class members?

  • How to get smartcard reader name in Windows 7 using C# or C/C++?

    - by AndrejaKo
    Hi! I'm trying to make a C# program which will use a C .dll (unfortunately, the .dll doesn't have good documentation) to access a smart card. One of the functions of the .dll uses name of the reader as argument. My problem is that I don't know how to get the name. After looking for answers I found something similar to what I need in an example here: http://msdn.microsoft.com/en-us/library/aa379803%28VS.85%29.aspx I'm looking for a way to get szReader value as described in the aforementioned example using C#. Can anyone help me or at least point me in the right direction? EDIT: Looks like nobody knows the answer so I'll expand the question: How do I get smartcard reader name using C/C++ and Windows API? I've read through MSDN site for smartcard API, but I couldn't find the function which will list readers. My idea is now to make a C/C++ .dll which will get in-between the smartcard .dll and C# program. It will produce list of readers, let user chose one and call the smartcard .dll using chosen name as argument.

  • ImpersonateLoggedOnUser and starting a new process that uses ocx fails.

    - by markus
    I write a c++ windows application (A), that uses LogonUser, LoadUserProfile and ImpersonateLoggedOnUser to gain the rights of another user (Y). Meaning the A starts using the user that is logged on on the workstation (X). If the user wants to elevate his rights he can just press a button and logon as another user without having to log himself out of windows and back in. The situation now is (according to the return values of the functions): LogonUser works, LoadUserProfile works and ImpersonateLoggedOnUser works as well. After the impersonation I start another process. This process is an application (B) that needs an OCX control. This fails and the application tells me that the .oxc file is not properly installed. The thing is, if I start B directly as the user that is logged on to the machine (X), it works. If I start B directly as the user (Y) to which I want to elevate my rights using A, it works. If I am logged in as (X) and choose "run as" (Y) in the explorer, it works! Do you know which steps I need to do to do the same as the "run as" dialog from windows?

  • UISlider how to set the initial value

    - by slim
    I'm pretty new at this iphone dev stuff and i'm working on some existing code at a company. The uislider i'm trying to set the initial value on is actually in a UITableViewCell and is a custom control. I was thinking in the cell init cell = (QuantitiesCell *)[self loadCellWithNibName:@"QuantitiesCell" forTableView:ltableView withStyle:UITableViewCellStyleDefault]; i could just call something like ((QuantitiesCell *)cell).value = 5; The actual QuantitiesCell class has the member value and the following functions -(void)initCell;{ if (listOfValues == nil) { [self initListOfValues]; } quantitiesSLider.maximumValue = [listOfValues count]-1; quantitiesSLider.minimumValue = 0; quantitiesSLider.value = self.value; } -(void)initListOfValues;{ listOfValues = [[NSMutableArray alloc] initWithCapacity:10]; int j =0; for (float i = minValue; i <= maxValue+increment; i=i+increment) { [listOfValues addObject:[NSNumber numberWithFloat: i]]; if (i == value) { quantitiesSLider.value = j; } j++; } } like i said, i'm pretty new at this so if i need to post more of the code to show whats going to get help, let me know, This slider always is defaulting to 1, the slider ranges usually from 1-10, and i want to set it to a specific value of the item i'm trying to edit.

  • Reading Code - helpful visualizers and browser tools

    - by wishi_
    Hi! I find myself reading 10 times more code than writing. My IDEs all are optimized to make me edit code - with completion, code assist, outlines etc. However if I'm checking out a completely new project: getting into the application's logics isn't optimized with these IDE features. Because I cannot extend what I don't fully understand. If you for example check out a relatively new project, frama-c, you realize that it has got plugins that are helpful to gain insight into "unfamiliar code": http://frama-c.com/plugins.html - However of course the project has a different scope. What I'm fully aware of. I'm looking for something that does helpful things for code-reading. Like: providing a graph, - reverse engineering UML e g., showing variable scopes showing which parts are affected by attempted modifications visualizing data-flow semantics showing tag-lists of heavily utilized functions ... My hope is that something like that exists. - That there're some Eclipse plugins I don't know or that there's a code-browser that has some of these features?

  • PHP manipulating multidimensional array values

    - by Joker
    I have a result set as an array from a database that looks like: array ( 0 => array ( "a" => "something" "b" => "something" "c" => "something" ) 1 => array ( "a" => "something" "b" => "something" "c" => "something" ) 2 => array ( "a" => "something" "b" => "something" "c" => "something" ) ) How would I apply a function to replace the values of an array only on the array key with b? Normally I would just rebuild a new array with a foreach loop and apply the function if the array key is b, but I'm not sure if it's the best way. I've tried taking a look at many array functions and it seemed like array_walk_recursive is something I might use, but I didn't have luck in getting it to do what I want. If I'm not describing it well enough, basically I want to be able to do as the code below does: $arr = array(); foreach ($result as $key => $value) { foreach ($value as $key2 => $value2) { $arr[$key][$key2] = ($key2 == 'b' ? $this->_my_method($value2) : $value2); } } Should I stick with that, or is there a better way?

  • Trying to compile a linux-based app on Mac OS X

    - by Scott
    I'm just trying to compile the linux-based FCEUX (NES emulator) on my mac, OS X 10.5 Leopard. I got all the dependencies (SDL, GTK+ 2) going and everything but of all things this is now my problem: Undefined symbols: "_compress", referenced from: SaveSnapshot() in video.o "_gzclose", referenced from: FCEU_fopen(char const*, char const*, char*, char*, int, char const**)in file.o "_crc32", referenced from: CalcCRC32(unsigned int, unsigned char*, unsigned int)in crc32.o _unzReadCurrentFile in unzip.o _unzReadCurrentFile in unzip.o "_uncompress", referenced from: NetplayUpdate(unsigned char*)in netplay.o FCEUSS_LoadFP(EMUFILE*, ENUM_SSLOADPARAMS) in state.o "_compress2", referenced from: FCEUNET_SendFile(unsigned char, char*)in netplay.o FCEUSS_SaveMS(EMUFILE*, int) in state.o "_inflateEnd", referenced from: _unzCloseCurrentFile in unzip.o "_inflate", referenced from: _unzReadCurrentFile in unzip.o "inflateInit2", referenced from: _unzOpenCurrentFile in unzip.o "_gzgetc", referenced from: FCEU_fopen(char const*, char const*, char*, char*, int, char const**)in file.o "_gzopen", referenced from: FCEU_fopen(char const*, char const*, char*, char*, int, char const**)in file.o "_gzread", referenced from: FCEU_fopen(char const*, char const*, char*, char*, int, char const**)in file.o "_gzseek", referenced from: FCEU_fopen(char const*, char const*, char*, char*, int, char const*)in file.o ld: symbol(s) not found collect2: ld returned 1 exit status scons: ** [src/fceux] Error 1 scons: building terminated because of errors. Those are zlib functions. It seems like it is loading the zlib.h ok, but the symbols aren't being linked in? Just to make sure I downloaded the latest zlib and did a make install, no help. I have no clue what's going on here, it seems like it should be pretty basic, that library is nothing special. Help would be appreciated. Thanks.

  • linearRGB conversion to/from HSL

    - by Otaku
    Does anyone know of a way to get HSL from an linearRGB color (not an sRGB color)? I've seen a lot of sRGB<-HSL conversions, but nothing for linearRGB<-HSL. Not sure if it is fundementally the same conversion with minor tweaks, but I'd appreciate any insight someone may have on this. Linear RGB is not the same as linearizing sRGB (which is taking [0,255] and making it [0,1]). Linear RGB transformation from/to sRGB is at http://en.wikipedia.org/wiki/SRGB. In VBA, this would be expressed (taking in linearized sRGB values [0,1]): Public Function sRGB_to_linearRGB(value As Double) If value < 0# Then sRGB_to_linearRGB = 0# Exit Function End If If value <= 0.04045 Then sRGB_to_linearRGB = value / 12.92 Exit Function End If If value <= 1# Then sRGB_to_linearRGB = ((value + 0.055) / 1.055) ^ 2.4 Exit Function End If sRGB_to_linearRGB = 1# End Function Public Function linearRGB_to_sRGB(value As Double) If value < 0# Then linearRGB_to_sRGB = 0# Exit Function End If If value <= 0.0031308 Then linearRGB_to_sRGB = value * 12.92 Exit Function End If If value < 1# Then linearRGB_to_sRGB = 1.055 * (value ^ (1# / 2.4)) - 0.055 Exit Function End If linearRGB_to_sRGB = 1# End Function I have tried sending in Linear RGB values to standard RGB_to_HSL routines and back out from HSL_to_RGB, but it does not work. I have seen almost no references that this can be done, except for two: A reference on http://en.wikipedia.org/wiki/HSL_and_HSV#cite_note-9 (numbered item 10). A reference on an open source project Grafx2 @ http://code.google.com/p/grafx2/issues/detail?id=63#c22 in which the contributor states that he has done Linear RGB <- HSL conversion and provides some C code in an attachment to his comment in a .diff file (which I can't really read :( ) My intent is to send from sRGB (for example, FF99FF (R=255, G=153, B=255)) to Linear RGB (R=1.0, G=0.318546778125092, B=1.0) using the code above (for example, the G=153 would be obtained in Linear RGB from sRGB_to_linearRGB(153 / 255)) to HSL, modify the Saturation by 350% and going back from HSL-Linear RGB-sRGB, the result would be FF19FF (R=255, G=25, B=255). Using available functions from .NET, such as .getHue from a System.Drawing.Color does not work in any sRGB space above 100% modulation of any HSL value, hence the need for Linear RGB to be sent in instead of sRGB.
