Require return type of function template to be specialization of a template
I've poked around on stackoverflow for a while, but either I don't understand templates enough to find a solution, or it simply hasn't been answered before. In this example: template <typename T> T f(); Is it possible to make the function require type T to be a specialization of the std::basic_string template? I could have the templ...
Undefined reference to operator new
I'm trying to build a simple unit test executable, using cpputest. I've built the cpputest framework into a static library, and am now trying to link that into an executable. However, I'm tied into a fairly complicated Makefile setup, because of the related code. This is my command line: /usr/bin/qcc -V4.2.4,gcc_ntoarmle_acpp-ne -lang...

This is not essential for my programs, but merely out of curiosity. Is it possible to, preferably using gcc, compile a 'fat' binary for Linux including multiple architectures such as combinations of amd64, i386, lpia and powerpc? ...
Tools/techniques for diagnosing C app crash on Windows
I have written an application in C, which runs as a Windows service. Most users can run the app without any problems, but a significant minority experience crashes caused by an Access Violation, so I know I have a bug somewhere. I have tried setting up virtual machines to mirror the users' configurations as closely as possible, but canno...

How to compile from gVim on Windows with GCC from Cygwin and then run the program?
I've been working at this all morning and I still can't find a way to easily bind a key to compile my program from the Windows version of gVim using the Cygwin GCC, and then run it. I'm kind of a novice to Bash scripting, and I haven't been able to make it create the .exe in the home directory (C:/cygwin/home) and then run it. What I h...
Where is a binary file once it's been built (for ffmpeg)?
I need to build ffmpeg for Mac for converting MOV to FLV in a Java application. I made and installed LAME and then FFMPEG, but I'm confused as to what file I should grab to include with the Java application. What is the binary file?

How to suppress boost::thread warnings with gcc ?
Hi, In my project, I recently decided to use boost::thread. My code compiles fine under Linux, but under Windows (either x86 or x64), I get the following warnings with gcc 4.5: In file included from C:\Boost\include\boost-1_44/boost/thread/shared_mutex.hpp:14:0, from C:\Boost\include\boost-1_44/boost/thread/detail/thre...
GCC vs MS C++ Compiler
I often read that the GCC compiler is much better than the Microsoft compiler on various forums and comment thread. This is always because "Micro$oft is evil" and that GCC is open-source. Are there any technical reasons that GCC is better? Are there any scenarios where one would want to use GCC over MS for windows development? Are there ...

Linking phase in distcc
Is there any particular reason that the linking phase when building a project with distcc is done locally rather than sent off to other computers to be done like compiling is? Reading the distcc whitepages didn't give a clear answer but I'm guessing that the time spent linking object files is not very significant compared to compilation....
