  • Should boost library be dependent on structure member alignments?

    - by Sorin Sbarnea
    I found, the hard way, that at least boost::program_options is dependent of the compiler configured structure member alignment. If you build boost using default settings and link it with a project using 4 bytes alignment (/Zp4) it will fail at runtime (made a minimal test with program_options). Boost will generate an assert indicating a possible bad calling convention but the real reason is the structure member alignment. Is there any way to prevent this? If the alignment makes the code incompatible shouldn't this be included in library naming?

  • C2244 when trying to call the pow function from inline assembly

    - by schrödingers cat
    I would like to call the pow function from inline assembly. The problem is i'm getting error C2244: 'pow' : unable to match function definition to an existing declaration. I'm new to assembly so this may be a trivial question but how do i resolve this? I guess it has something to do with the compiler not beeing able to properly resolve the overload of pow. The following code fragment is causing the error: do_POW: // push first argument to the stack sub esp, size value_type fld qword ptr [ecx] fstp qword ptr [esp] // push second argument to the stack sub esp, size value_type fld qword ptr [ecx - size value_type] fstp qword ptr [esp]and pop fpu stack // call the pow function call pow sub ecx, size value_type fstp qword ptr [ecx] add esp, 2 * size value_type jmp loop_start

  • Printing out this week's dates in perl

    - by ABach
    Hi folks, I have the following loop to calculate the dates of the current week and print them out. It works, but I am swimming in the amount of date/time possibilities in perl and want to get your opinion on whether there is a better way. Here's the code I've written: #!/usr/bin/env perl use warnings; use strict; use DateTime; # Calculate numeric value of today and the # target day (Monday = 1, Sunday = 7); the # target, in this case, is Monday, since that's # when I want the week to start my $today_dt = DateTime->now; my $today = $today_dt->day_of_week; my $target = 1; # Create DateTime copies to act as the "bookends" # for the date range my ($start, $end) = ($today_dt->clone(), $today_dt->clone()); if ($today == $target) { # If today is the target, "start" is already set; # we simply need to set the end date $end->add( days => 6 ); } else { # Otherwise, we calculate the Monday preceeding today # and the Sunday following today my $delta = ($target - $today + 7) % 7; $start->add( days => $delta - 7 ); $end->add( days => $delta - 1 ); } # I clone the DateTime object again because, for some reason, # I'm wary of using $start directly... my $cur_date = $start->clone(); while ($cur_date <= $end) { my $date_ymd = $cur_date->ymd; print "$date_ymd\n"; $cur_date->add( days => 1 ); } As mentioned, this works - but is it the quickest/most efficient/etc.? I'm guessing that quickness and efficiency may not necessarily go together, but your feedback is very appreciated.

  • What kind of assemblies can be called using P/Invoke ?

    - by milan
    Hi all, I allready asked at: Is it possible to call unmanaged code using C# reflection from managed code ? if it is possible to call C/C++ library unmanaged function with Invoke and reflection from .NET and the answer is yes. What I am not clear about is can I call using P/Invoke ANY assembly written/compiled/build with other compilers on my Windows PC like Labwindows/CVI(have some kind of C compiler) or Java written dll's, exe. If this is possible is it the same as explained in above given link using "Marshal.GetDelegateForFunctionPointer" ? Thanks! Milan.

  • GCC ICE -- alternative function syntax, variadic templates and tuples

    - by Marc H.
    (Related to C++0x, How do I expand a tuple into variadic template function arguments?.) The following code (see below) is taken from this discussion. The objective is to apply a function to a tuple. I simplified the template parameters and modified the code to allow for a return value of generic type. While the original code compiles fine, when I try to compile the modified code with GCC 4.4.3, g++ -std=c++0x main.cc -o main GCC reports an internal compiler error (ICE) with the following message: main.cc: In function ‘int main()’: main.cc:53: internal compiler error: in tsubst_copy, at cp/pt.c:10077 Please submit a full bug report, with preprocessed source if appropriate. See <file:///usr/share/doc/gcc-4.4/README.Bugs> for instructions. Question: Is the code correct? or is the ICE triggered by illegal code? // file: main.cc #include <tuple> // Recursive case template<unsigned int N> struct Apply_aux { template<typename F, typename T, typename... X> static auto apply(F f, const T& t, X... x) -> decltype(Apply_aux<N-1>::apply(f, t, std::get<N-1>(t), x...)) { return Apply_aux<N-1>::apply(f, t, std::get<N-1>(t), x...); } }; // Terminal case template<> struct Apply_aux<0> { template<typename F, typename T, typename... X> static auto apply(F f, const T&, X... x) -> decltype(f(x...)) { return f(x...); } }; // Actual apply function template<typename F, typename T> auto apply(F f, const T& t) -> decltype(Apply_aux<std::tuple_size<T>::value>::apply(f, t)) { return Apply_aux<std::tuple_size<T>::value>::apply(f, t); } // Testing #include <string> #include <iostream> int f(int p1, double p2, std::string p3) { std::cout << "int=" << p1 << ", double=" << p2 << ", string=" << p3 << std::endl; return 1; } int g(int p1, std::string p2) { std::cout << "int=" << p1 << ", string=" << p2 << std::endl; return 2; } int main() { std::tuple<int, double, char const*> tup(1, 2.0, "xxx"); std::cout << apply(f, tup) << std::endl; std::cout << apply(g, std::make_tuple(4, "yyy")) << std::endl; } Remark: If I hardcode the return type in the recursive case (see code), then everything is fine. That is, substituting this snippet for the recursive case does not trigger the ICE: // Recursive case (hardcoded return type) template<unsigned int N> struct Apply_aux { template<typename F, typename T, typename... X> static int apply(F f, const T& t, X... x) { return Apply_aux<N-1>::apply(f, t, std::get<N-1>(t), x...); } }; Alas, this is an incomplete solution to the original problem.

  • When using the getInstance() method of the abstract java.text.NumberFormat class, what is the actual

    - by iamchuckb
    This question expands upon the one at abstract-class-numberformat-very-confused-about-getinstance. I feel that this question is different enough to merit being asked on its own. In the answers to that question, it was stated that a code statement such as NumberFormat en = NumberFormat.getInstance(Locale.US); returns an object that is a subclass of the java.text.NumberFormat class. It makes sense to me why the return type can't be just an instance of NumberFormat since that is an abstract class. Rather, it was stated that the returned object is at least an instance of NumberFormat, but actually something else. My question is this: what specifically is the class of the object that is returned? In the Sun documentation the only subclasses I see are ChoicesFormat and DecimalFormat. Is there some sort of behind the scenes compiler voodoo going on here? Thanks in advance!

  • Adding Java packages to GWT

    - by Organiccat
    I've tried searching but couldn't come up with a defined way on how to add your own packages to a GWT project. My tree structure looks like this: -com.mycompany -public MyApplication.html MyApplication.gwt.xml -com.mycompany.client MyApp.java -com.mycompany.gui TableLayout.java The answer I've seen out there says to add the packages relative to the root directory of the gwt.xml file, like so: <module> <inherits name="com.google.gwt.user.User" /> <entry-point class="com.mycompany.client.MyApp" /> <source path="client" /> <source path="gui" /> </module> It then complains: Unable to find type 'com.technicon.client.MyApp' Hint: Previous compiler errors may have made this type unavailable Hint: Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly Can anyone tell me what I'm doing wrong and how to fix this?

  • Target .NET 3.5 C++/CLI in Visual Studio 2010 Beta 2

    - by jeffora
    Has anyone had any success converting a VS 2008 C++/CLI (vcproj) project to a VS 2010 project (vcxproj), whilst maintaining .NET 3.5 as the target framework? I haven't been able to do this and get the project to build successfully. The project compiles fine in VS2008 as .NET 3.5, and fine in VS2010 as .NET 4.0, but I am unable to target .NET 3.5 in 2010. The IDE doesn't seem to provide an option for it, and modifying the vcxproj file by adding <TargetFrameworkVersion>v3.5</TargetFrameworkVersion> causes compilation to fail with the folling error: Error 1 error C1001: An internal error has occurred in the compiler. According to this link, there is apparently some differences in compilers used between VS2008 and 2010, but manually editing the project file was still suggested as a solution. Does anyone have any idea on this?

  • Help me avoid a resonance cascade.

    - by SLC
    Hi, my name is Dr. Kleiner, and I'm a senior scientist working at the Black Mesa Research Facility. I've just finished compiling my code to analyse a large unknown sample we've come across. Unfortunately, there were 19 build errors and 42 warnings, but I've been told the experiment must go ahead. Time is critical, we've already got one of our newest employees who is suiting up as I type this to complete the experiment. I really need some help. Can you think of anything last minute to stop a potential resonance cascade? Someone has hidden my glasses again... Anyway, I hope I never see a resonance cascade, and definitely don't want to create one. It's my lunch break in 5 minutes, and my casserole is already in the microwave ready. Please, give me some advice. If it helps I wrote all of the code to analyse the sample and activate the sampler machine in BASIC. Edit: Oh god! They're everywhere! Send assista

  • Using Pylint with Django

    - by rcreswick
    I would very much like to integrate pylint into the build process for my python projects, but I have run into one show-stopper: One of the error types that I find extremely useful--:E1101: *%s %r has no %r member*--constantly reports errors when using common django fields, for example: E1101:125:get_user_tags: Class 'Tag' has no 'objects' member which is caused by this code: def get_user_tags(username): """ Gets all the tags that username has used. Returns a query set. """ return Tag.objects.filter( ## This line triggers the error. tagownership__users__username__exact=username).distinct() # Here is the Tag class, models.Model is provided by Django: class Tag(models.Model): """ Model for user-defined strings that help categorize Events on on a per-user basis. """ name = models.CharField(max_length=500, null=False, unique=True) def __unicode__(self): return self.name How can I tune Pylint to properly take fields such as objects into account? (I've also looked into the Django source, and I have been unable to find the implementation of objects, so I suspect it is not "just" a class field. On the other hand, I'm fairly new to python, so I may very well have overlooked something.) Edit: The only way I've found to tell pylint to not warn about these warnings is by blocking all errors of the type (E1101) which is not an acceptable solution, since that is (in my opinion) an extremely useful error. If there is another way, without augmenting the pylint source, please point me to specifics :) See here for a summary of the problems I've had with pychecker and pyflakes -- they've proven to be far to unstable for general use. (In pychecker's case, the crashes originated in the pychecker code -- not source it was loading/invoking.)

  • Debugging a release version of a DLL (with PDB file)

    - by Martin
    If I have a DLL (that was built in release-mode) and the corresponding PDB file, is it possible to debug (step-into) classes/methods contained in that DLL? If so, what are the required steps/configuration (e.g. where to put the PDB file)? Edit: If have the PDB file in the same place as the DLL (in the bin/debug directory of a simple console test application). I can see that the symbols for the DLL are loaded (in the Output window and also in the Modules window), but still I cannot step into the methods of that DLL. Could this be the result of compiler optimizations (as described by Michael in his answer)?

  • BeautifulSoup can't parse a webpage?

    - by JLTChiu
    I am using beautiful soup for parsing webpage now, I've heard it's very famous and good, but it doesn't seems works properly. Here's what I did import urllib2 from bs4 import BeautifulSoup page = urllib2.urlopen("http://www.cnn.com/2012/10/14/us/skydiver-record-attempt/index.html?hpt=hp_t1") soup = BeautifulSoup(page) print soup.prettify() I think this is kind of straightforward. I open the webpage and pass it to the beautifulsoup. But here's what I got: Warning (from warnings module): File "C:\Python27\lib\site-packages\bs4\builder\_htmlparser.py", line 149 "Python's built-in HTMLParser cannot parse the given document. This is not a bug in Beautiful Soup. The best solution is to install an external parser (lxml or html5lib), and use Beautiful Soup with that parser. See http://www.crummy.com/software/BeautifulSoup/bs4/doc/#installing-a-parser for help.")) ... HTMLParseError: bad end tag: u'</"+"script>', at line 634, column 94 I thought CNN website should be well designed, so I am not very sure what's going on though. Does anyone has idea about this?

  • How do I get the XAML comiler to use textual content property on custom classes?

    Given a simple C# class definition like: [System.Windows.Markup.ContentProperty("PropertyOne")] public class SimpleBase { public string PropertyOne { get; set; } public string PropertyTwo { get; set; } } why is it not possible to ommit the sys:string tags around the word Test in the xaml below. <custom:SimpleBase x:Class="TestType" xmlns:custom="clr-namespace:ConsoleApplication1;assembly=" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:sys="clr-namespace:System;assembly=mscorlib"> <sys:String>Test</sys:String> </custom:SimpleBase> Somehow the compiler correctly coverts text to string for the type String, why doesn't it work for my custom type?

  • New asp "showat" attribute required inconsistently in VS2010. Why?

    - by Patrick Karcher
    When I generate code using T4 templates in Visual Studio 2010, I get the following error for each of my asp controls when I try to compile: Control "ddState" is missing required attribute "showat". I have never gotten this error in previous versions of .NET. Further, I don't get this error when I manually construct my pages either by dragging/dropping, nor do I get it when I type out the control text myself. When I generate code, I have to manually add showat="client" to my tag for the compiler to be happy. It was my understanding that I never had to explicitly specify this tag. The following: <asp:dropdownlist id="ddState" runat="server" showat="client" /> solves the problem. Why do I have to add this to generated code but not other times? (It's a VS-2010 webforms project, using VB, in case that makes a difference.)

  • Problems with dotLess Stopping characters and hacks list?

    - by rDeeb
    Have any one run into trouble when running dotLess and having hacks on your CSS files? Been working on a project... just installed dotLess after one year of development to ease a little bit the job of creating new CSS files for some new functionality of the web site, and recently our old CSS is not working correctly. Viewing the resulting CSS files we realized that the dotLess compiler stopeed at some hacks like this one: html>/**/body #itemTable .informationView fieldset textarea { min-height: 1.3em; height: 1.3em; } So we were wondering if there is any list of stopping words or hacks for dotLess?

  • User defined top level control in XAML

    A normal UserControl looks like this in XAML: <UserControl x:Class="mynamespace.foo" ...namespaces...> <!-- content --> </UserControl> I'd like to be able to define my own top level object, along the lines of: <MyControl x:Class="mynamespace.mycontrol" ...namespaces...> <!-- content --> </UserControl> Where MyControl derives from a UserControl itself. Of course the compiler complains about "MyControl" not being found. Is there a way around this?

    I want to generate a HTML-Documentation for my Javascript code. The comments in my code are written in a format, the Google Closure Compiler can use to optimize my code. Example: /** * Class for handling timing events. * * @param {number=} opt_interval Number of ms between ticks (Default: 1ms). * @param {Object=} opt_timerObject An object that has setTimeout, setInterval, * clearTimeout and clearInterval (eg Window). * @constructor * @extends {goog.events.EventTarget} */ goog.Timer = function(opt_interval, opt_timerObject) { ... } I am looking for something like http://yardoc.org for Javascript. What tools can you recommend? Are there any specific tools for Google Closure code?

  • "Cannot convert to IComparer"

    I have the following IComparer defined for boxed RegistryItem objects: public class BoxedRegistryItemComparer : IComparer<object> { public int Compare(object left, object right) { RegistryItem leftReg = (RegistryItem)left; RegistryItem rightReg = (RegistryItem)right; return string.Compare(leftReg.Name, rightReg.Name); } } I want to use this to sort an ArrayList of boxed RegistryItems (It really should be a List<RegistryItem, but that's out of my control). ArrayList regItems = new ArrayList(); // fill up the list ... BoxedRegistryItemComparer comparer = new BoxedRegistryItemComparer(); ArrayList.sort(comparer); However, the last line gives the compiler error: "Cannot convert from BoxedRegistryItemComparer to System.Collections.IComparer". I would appreciate it if someone could point out my mistake.

    I use to create an application that uses the windows speech recognition engine or the SAPI. its like a game for pronunciation that it give you score when you pronounce it correctly. but when i started experiments with SAPI, it has poor recognition unless if you load a grammar on it (XML) its give best recognition result. but the problem now is closest pronunciation from the input text will be recognize. for example: Database - dedebase - correct. even if you mispronounce it. it gives you correct answers. without using the xml grammar when you say database it give you "in the base/the base/data base/etc..." please post your answer,suggestion,clarification. votes for best answer. is it possible or not? by the way i use delphi compiler on the projects....
