When I looked at the mingw toolchain several months ago, I could not get it to cleanly install and build on the current Fedora Core at the time. I am now using the current FC and the beta mingw based on gcc 4.6 and have gotten it to work, so I seem to have a working environment that can compile 32-bit and 64-bit windows executables. > > If you stumble across any problems with any of the toolchains, feel free > to let us know about it so we can help to resolve these issues. I am having a problem creating multi-threaded executables that are statically linked. Even though I am using the -static flag, the resulting executable has a dependency for pthreadGC2.dll. Unfortunately, for my application we do not wish to have ANY DLL dependencies. Here is my linkage line: x86_64-w64-mingw32-g++ -D_FORTIFY_SOURCE=2 -Wall -g -Wno-format --static -mthreads -o tigerdeep.exe md5.o sha1.o sha256.o whirlpool.o tiger.o main.o hashlist.o multihash.o display.o hash.o dig.o helpers.o xml.o files.o threadpool.o -lws2_32 -lgdi32 -liberty -lpthread The problem seems to be that all of the libraries have been built for dynamic linking.

hi, I'm trying to rebuild some of the packages from the svn source and when I try to build cross-qt, the qt-darwinx-compatibility.patch seems to be missing Mathieu

Kal, thanks for the information. I am writing C++ code. We are attempting to create .EXE files that have no external dependencies and do not require the use of ANY DLL that is not part of the standard Windows system. Does -shared-libgcc make the system require a GCC DLL? If so, we can't do that. Specifying -mthreads creates a dependcy fir mingwm10.dll. According to some posts I've read the dependency goes away if you are using GCC 4.5.2 or above: • http://comments.gmane.org/gmane.comp.gnu.mingw.user/36738 It is not clear to me how to get the current mingw (32 or 64) running in cross-compiler mode on Ubuntu or MacOS. A while ago I looked at the Fedora build system and it was broken too. However, I need to build both 32-bit and 64-bit executables and I need a system that is repeatable for others, so it looks like I'm going to have to spend some serious time on this over the next 2-3 weeks. I am happy to do it with Fedora or Ubuntu or Mac, but I need something that's easy, and I need to generate both 32-bit and 64-bit binaries. Have the Fedora repositories been fixed yet?

Hi. I'm still trying to get pthreads working reliably on mingw32 and mingw64. My question today --- if I am writing multi-threaded code, do i need to supply the -mthreads compiler option? Thanks

mingw23-SDL_mixer can't open audio device?
by Christopher Thielen 05 Sep '11

05 Sep '11

Has anyone else experienced issues with mingw32-SDL_mixer (or mingw32-SDL's audio API for that matter) not being able to open the audio device, both under Wine and MS Windows when using Fedora MinGW? I can't get the SDL_mixer source-included playwave.c to work using fedora-mingw, but the same code _does_ work fine if I download MinGW on Windows and build it there. I should mention playwave.c, non-cross-compiled (just under Fedora) works fine as well. Thanks in advance for any help, Christopher Thielen
