• How to install Qt on Windows after building?

  - by Piotr Dobrogost

  I can't find any information on how to install Qt built on Windows. In wiki article How to set up shadow builds on Mac and Linux there's description of -prefix option in configure script but this option is not available on Windows. I know I can use Qt right from the build folder but it does not seem the right thing not to perform an install step. One problem with this approach is size; Qt's build folder takes about 4GB space whereas after installing using binary installer Qt takes about 1GB space. I guess the difference is due to temporary files created during building. I hope some install procedure would install (copy) only needed files leaving temporary files in the build folder.

• A Few Questions About QT

  - by ForgiveMeI'mAN00b

  Is it free? It looks like on the website it says "Try Now", which makes me worry that it just gives you a demo. Do you have to pay the QT company anything to distribute a program using QT, or can you just throw it (the program) out there and just say you used QT. Is it native c++, or something wierd, like, the same way .NET programs aren't actual c++, they just look like it. Would somebody who uses my program have to install the QT framework before they can run it, or will the program run without any installation? Can it easily be compiled to work on a Windows, Linux and Mac OS?

• Why does SQLite say it can't read SQL from a file?

  - by Gavin

  Hi all. I have a bunch of SQL in a file, which creates the tables and so forth. The problem is that the .read command simply returns "can't open xxx" when I try to execute it. I've set the permissions to everybody read/write, but that didn't help. I can cat the file from the command line and see it fine. This is under Mac OS 10.6.3. Anybody have any idea here? Thanks!

• NSTableView doesn't populate with array objects until a new object is added via the controller

  - by Luke

  I have an NSTableView and an array controller set up as shown here, using cocoa bindings: https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/TableView/PopulatingViewTablesWithBindings/PopulatingView-TablesWithBindings.html#//apple_ref/doc/uid/10000026i-CH13-SW3 In my app delegate during applicationDidFinishLaunching I have the following snippet in here, initialising the array and filling it with objects array = [[NSMutableArray alloc] init]; SomeObject* foo = [[Object alloc] init]; foo.text = @"sup"; [array addObject:foo]; //Repeat this a few times However, when I build the app and run it I end up with an empty table. However, if I bind a button to the array controller's add: input and click it during runtime (this adds a new object to the array and table) then the table will show the new object first, with the objects added during applicationDidFinishLaunching following it. Why does this happen? And is there a way to make my table populate without having to add an element first?

• Setting enum values to 4-byte strings - why?

  - by psychotik

  I saw code similar to this in the Mac OS SDK: enum { kAudioFileStreamProperty_ReadyToProducePackets = 'redy', kAudioFileStreamProperty_FileFormat = 'ffmt', kAudioFileStreamProperty_DataFormat = 'dfmt', kAudioFileStreamProperty_FormatList = 'flst', kAudioFileStreamProperty_MagicCookieData = 'mgic', kAudioFileStreamProperty_AudioDataByteCount = 'bcnt', kAudioFileStreamProperty_AudioDataPacketCount = 'pcnt', kAudioFileStreamProperty_MaximumPacketSize = 'psze', kAudioFileStreamProperty_DataOffset = 'doff', kAudioFileStreamProperty_ChannelLayout = 'cmap', kAudioFileStreamProperty_PacketToFrame = 'pkfr', kAudioFileStreamProperty_FrameToPacket = 'frpk', kAudioFileStreamProperty_PacketToByte = 'pkby', kAudioFileStreamProperty_ByteToPacket = 'bypk', kAudioFileStreamProperty_PacketTableInfo = 'pnfo', kAudioFileStreamProperty_PacketSizeUpperBound = 'pkub', kAudioFileStreamProperty_AverageBytesPerPacket = 'abpp', kAudioFileStreamProperty_BitRate = 'brat' }; It's the first time I've seen this - I assume the compiler assigns the 32-bit integer equivalent of the strings to the enum values. I cannot think of a single good reason why this might be preferred over using simple integers. It looks hideous in a debugger (how do you tell which of these values corresponds to 1919247481?) and makes debugging just hard in general. So, is there any reason where assigning such strings to enum values actually makes sense.

• What workflow should I use for JavaScript editing?

  - by Patrick

  Warning: I have very little JavsScript experience. In my past programming experience, I usually have a standalone interpreter/compiler, a text editor and a command line to compile/run my software or my tests (I love test driven development). I really like it this way, since I have the feeling of being in complete control over the tools. However, editing JavaScript I need to put statements in a text file , open my web browser and click on reload. I don't feel comfortable with it, as I cannot really see what is going on (besides some alert boxes). Can you suggest me (I'm on a Mac) another workflow? Perhaps with a debugger? Is there a standalone JavaScript interpreter?

• Endless saving of CoreData Context

  - by Robert

  Sometimes I noticed that a 'save:' operation an a ManagedObjectContext never returns and consumes 100% CPU. I'm using an SQL Store in a GarbageCollected environment (Mac OS X 10.6.3). The disk activity shows about 700 KB/s writing. While having a look at the folder that contains the sqlite database file the "-journal" file appears and disappears, appears and disappears, ... This is part of the call graph from the process analysis: 2203 -[NSManagedObjectContext save:] 1899 -[NSPersistentStoreCoordinator(_NSInternalMethods) executeRequest:withContext:] 1836 -[NSSQLCore executeRequest:withContext:] 1836 -[NSSQLCore saveChanges:] 1479 -[NSSQLCore performChanges] ... 335 -[NSSQLCore recordChangesInContext:] ... 20 -[NSSQLCore rollbackChanges] ... 2 -[NSSQLCore prepareForSave:] ... 62 -[NSPersistentStoreCoordinator(_NSInternalMethods) _checkRequestForStore:originalRequest:andOptimisticLocking:] ... 1 -[NSPersistentStore(_NSInternalMethods) _preflightCrossCheck] ... 184 -[NSMergePolicy resolveConflicts:] ... 120 -[NSManagedObjectContext(_NSInternalChangeProcessing) _prepareForPushChanges:] ... Everything a happening in the main GUI thread. Any ideas what I can to do to resolve the problem?

• How to write a program that mimics Fiddler by using tcpdump or from scratch?

  - by ????

  When Fiddler is not on Mac OS X or Ubuntu, and if we don't install/use Wireshark or any other more heavy duty tools, what is a way to use tcpdump so that 1) It can print out GET /foo/bar HTTP/1.1 [request content in RAW text] [response content in RAW text] POST /foo/... HTTP/1.1 this should be able to be done by tcpdump or by using tcpdump in a short shell script or Ruby / Python / Perl script. 2) Actually, it can be neat if a script can output HTML, with GET /foo/bar HTTP/1.1 POST /foo/... HTTP/1.1 on the page, for any browser to display, and then when clicked on any of those lines, it will expand to show the RAW content like (1) above does. Click again and it will hide the details. The expansion UI can be done using jQuery or any JS library. The script may be short... possibly less than 20 lines? Does anybody know how to do it either for (1) or (2)?

• I need to create a contest....

  - by creocare

  I'm working on a contest where users vote for contestants. Each contestant will have a bio. I was wondering what would be the best way to approach this? Should I do this in php or javascript? Should I use a database to collect data? Should I use sqlite3? If I use sqlite3 how do i install that on my mac? I'm very new to all this but I'm a quick learner. Thanks for any advice.

• Hook key & key combinations from keyboard with Qt 4.6

  - by Viet

  Let's say I have a window-less application which has only an icon on the Taskbar (Windows, Mac OS X & Linux). I want it to capture some key & key combinations, let's say Right Control + Right Shift. Upon keying in correct, combination, it will do something, say take screenshot. I can do window-less app, icon on the Taskbar and screen capture but I don't know how to monitor keyboard globally for key combinations. Please kindly advise. Any help or hint is greatly appreciated! Thanks in advance!

• Vim: How to exchange key bindings? (bind '|' on '7' key)

  - by duddle

  Having the German Mac Keyboard Layout, it is a pain to type | as it is bound to <A-7> and it is hard for me to reach the Alt key. Thus, I'd like to do the following remapping (exchanging the binding for | and 7): imap 7 <Bar> imap <A-7> 7 The first one works, the second one does not. I have already tried all combinations with inor (no remap) but wasn't successful. Maybe I don't get the concept of remapping. Or I am missing something else.

• Numeric GUI bottleneck

  - by Physic

  Hi all, I've made a GUI to set up and start a numerical integrator using PyQT4, Wing, QT, and Python 2.6.6, on my Mac. The thing is, when I run the integrator form the GUI, it takes very many times longer than when I crudely run the integrator from the command line. As an example, a 1000 year integration took 98 seconds on the command line and ~570 seconds from the GUI. In the GUI, the integration runs from a thread and then returns. It uses a a queue to communicate back to the GUI. Does anyone have any ideas as to where the bottleneck is? I suspect that others may be experiencing something like this just on a smaller scale. t = threading.Thread( target=self.threadsafe_start_thread, args=( self.queue, self.selected ) ) t.start() Thanks!

• convert flv to mp3 with Java

  - by krial

  Hi, I'm pretty new in developing programs in Java. I'm currently writing a program that converts a flv video into mp3. I have already written such a program in Visual Studio.net C#, but the Problem is, that it isn't cross platform compatible... I used the ffmpeg binary to convert the video into mp3, but I can't find ffmpeg binaries for Mac and Linux. (if so, I could start the specific binaries from java, depending on the OS) So I tried to convert the video with Xuggle, but the final mp3 has 0 bytes. My current code is the following: IMediaReader reader = ToolFactory.makeReader("video.flv"); reader.addListener(ToolFactory.makeWriter("music.mp3", reader)); while (reader.readPacket() == null) do {} while(false); Thanks in advance. p.s sorry for my bad english

• Why is Python 3.1.3 in the header listed as a syntax error?

  - by squashua

  Hi, I'm a newbie programmer so I'll do my best to clearly ask my question. I'm running Python scripts in Mac 10.6.5 and now trying to write and save to a text file (following instructions in HeadsUp Python book). Whenever I hit function+F5 (as instructed) I get the same "invalid syntax" error and Idle highlights the "1" in "Python 3.1.3" of the header. Here's the header to which I'm referring: Python 3.1.3 (r313:86882M, Nov 30 2010, 09:55:56) [GCC 4.0.1 (Apple Inc. build 5494)] on darwin Type "copyright", "credits" or "license()" for more information. Extremely frustrating. I've checked and rechecked the code but this doesn't seem to be code related because the "syntax error" is in regards to the header text that posts in every Idle/Python session. Help anyone? Thanks, Squash

• Are memory leaks ever ok?

  - by Imbue

  Is it ever acceptable to have a memory leak in your C or C++ application? What if you allocate some memory and use it until the very last line of code in your application (for example, a global object's deconstructor)? As long as the memory consumption doesn't grow over time, is it OK to trust the OS to free your memory for you when your application terminates (on Windows, Mac, and Linux)? Would you even consider this a real memory leak if the memory was being used continuously until it was freed by the OS. What if a third party library forced this situation on you? Would refuse to use that third party library no matter how great it otherwise might be? I only see one practical disadvantage, and that is that these benign leaks will show up with memory leak detection tools as false positives.

• select subquery cause mysql server to be unresponsive

  - by Xiao

  DELETE FROM item_measurement WHERE measurement_id IN ( SELECT (-id) AS measurement_id FROM invoice_item WHERE invoice_id = 'A3722' ) I've really tried hard to find what's wrong with the code. I tried to run this in a php page, which doesn't respond. I also tried the same line in phpmyadmin, infinite spinning circle and I had to restart the server(MAMP on Mac 10.9). No error was given in browser/ If I run the delete and select separately, they both finish very quickly. I don't think it's a performance issue because the separate run took < 0.1 sec each. Thanks for any help in advance. Edit: I also found that a simple select statement will also suspend mysql: select * from item_measurement where measurement_id in (select -id from invoice_item where invoice_id='A3722')

• Creating many native GUI frontends for a cross-platform application

  - by Hugh Young

  I've been away from GUI programming for quite some time so please pardon my ignorance. I would like to attempt the following: Write a Mac OSX app but still be able to port to Win/Linux (i.e. C++ core with Obj-C GUI) Avoid Qt/other toolkits on OSX (i.e. talk to Cocoa directly - I feel that many Qt apps I use stick out like sore thumbs compared to the rest of my system) Not as important, but it would be nice to avoid Visual Studio if it means I can have the freedom to use newer C++ features even on Windows if they help create better code. I believe this configuration might get me what I'm looking for: Core C++ Static Library OSX GUI (Cocoa) Windows GUI (Qt+MinGW?) OR (no new C++ features, Visual Studio + ManagedC++/C#/????) Linux GUI (Qt) Once again, sorry for my ignorance but is this possible? Is this sane? Are there any real-world open source examples accomplish something like this?

• Match a word with similar words using Solr?

  - by fayer

  I want to search for threads in my mysql database with Solr. But i want it to not just search the thread words, but for similar words. Eg. if a thread title is "dog for sale" and if the user searches for dogs the title will be in the result. and also if a user searches for "mac os x" the word "snow leopard" will appear. and the ability to link words the application thinks is related eg. house and apartment. how is this kind of logic done? i know that you can with solr look up words in a dictionary file you create/add, so solr will look for dogs and see what related words there are (eg. dog). but where do you find such a dictionary? i have no idea about this kind of implementation. please point me into right direction. thanks

• NoMethodError using Memcached Sinatra-style

  - by sevennineteen

  I've just installed Memcached on my Mac and updated my Sinatra app configuration as described in Heroku's documentation, but I'm getting a NoMethodError when trying to use the hash-based syntax they specify: >> CACHE['color'] = 'blue' >> CACHE['color'] Using explicit get and set methods as below seems to work fine. >> CACHE.set('color', 'blue') >> CACHE.get('color') If necessary I can use the latter syntax, but the former seems more elegant. I haven't tested this on Heroku's environment since I'd like whatever implementation I use to work on my local environment as well. Thanks!

• Cross platform, Interactive text-based interface with command completion

  - by trojanfoe

  Does anyone know of a C++ library that will provide a text-based interactive interface? I want to create two versions of an application; a console based program that will perform whatever actions are given on the command line or interactively at the console as well as a GUI based program (Mac Cocoa and Windows MFC). Both versions will share a common C++ backend. For the console based program I would like similar history abilities to readline (which I cannot use as this application will be closed source) with command completion (Tab-activated for example). Perhaps there is something like this already available?

• node.js simply does not run

• What does that mean? "mi_cmd_stack_list_frames: Not enough frames in stack."

  - by HelloMoon

  Debugger is telling me this, when I run my app on device: Program received signal: “EXC_BAD_ACCESS”. mi_cmd_stack_list_frames: Not enough frames in stack. mi_cmd_stack_list_frames: Not enough frames in stack. I don't get information about where in code that happens. That's all I get. Any idea what that could mean? The app crashes after that. When the device is not connected to the mac, it still crashes, so not a debugger problem.

• from JS to iphone dev - what's the best language to start with?

  - by Enkai

  I am a total beginner and would like to eventually learn to develop for the iphone. I have just done a beginner's CS course where the language we learned was JavaScript. We studied basic concepts like: variables, arrays, loops (for,while,if,if..else..), properties and functions. I'm wondering if I am starting in the right/wrong place by following this book: Learn C on the Mac by Dave Mark? I have read a few chapters and am finding it a bit hard to get my head around the way that C works, for example the way that Strings are printed seems overly complicated as compared to JS. Do you think that JS was the wrong language to start off with and would I be better to go from JS straight to Objective-C rather than to C? I have tried to read up on previous threads on the merits/demerits of learning C first but haven't found any that relate JS to learning C/Obj C/ Cocoa. Any advice appreciated as I am very new to this. Thanks
