(no more msvcr80.dll) Should I be fine with that to not need redist anymore? Yes

The MSVC++ DLL's are also ABI incompatible among versions. Even Service Packs break ABI compatibility. sigh...I'm a happy Linux user but need to support Windows...of course. How to see the toolchain? I remember to have seen (vc build?) in dependency walker msvcpd80.dll or alike. Would that

Hi  it works with mingw32 on Vista64 or on Linux/gcc 32 and 64bit. But with mingw64 I get: a segmentation fault at IMG_Load: static int LoadGLTex(char *pFileName, int TextureId) { SDL_Surface* image = IMG_Load(pFileName); Any help on what to change? Many thanks Mike

[Mingw-w64-public] Segfault in legitimate (?) code

Hi, I'm having some trouble with my personal project I develop using mingw-w64. I tried different compiler versions (sezero's 4.4 and 4.5, and the november mingw autobuild). All segfault, at the same spot in libstdc++-v3 (gdb info from sezero's 4.4 build seemed to provide the most information): P
