Re: [flac-dev] Patch for cross compilation with MinGW32

Are these options somehow wrong? It worked fine when I compiled libogg-0.dll. Anyway, I attached a patch to allow cross compilation with MinGW32 on my machine again: First, I moved the implementation of *safe_malloc_mul_2op_ to alloc.h, just like all the other alloc implementations, and removed the thereby obsolete alloc.c implementation from grabbag. Second, I just wrapped FLAC__clz_soft_uint32 with an #ifndef __MINGW32__. I tested the patch for both Linux and MinGW32 compiles, and both result in functional programs. It works for me.. with mingw32-cross-gcc-4.7.0-8.43.x86_64 and the resulting binaries also work. ___ flac-dev mailing list flac-dev@xiph.org http://lists.xiph.org/mailman/listinfo/flac-dev

I configured the FLAC build with --host=i586-mingw32msvc --target=i586-mingw32msvc --build=i586-linux but ran into several linker problems. Are these options somehow wrong? Nope, seems about right. First, I moved the implementation of *safe_malloc_mul_2op_ to alloc.h, just like all the other alloc implementations, and removed the thereby obsolete alloc.c implementation from grabbag. Err, probably not a good idea. I assume you moved it there and made it inline, but GCC on x86-64 complains that it cannot inline it. Second, I just wrapped FLAC__clz_soft_uint32 with an #ifndef __MINGW32__. I tested the patch for both Linux and MinGW32 compiles, and both result in functional programs. I'm pretty sure there were warnings under linux. You should configure with ./configure --enable-gcc-werrror whcih turns all warnings into errors. I'm trying to keep the FLAC code warning free.
