Hi, John and All, I've run into a real issue: Following through the "MINGW HOWTO", while making lib-theora 1.0 alpha7 I've got: ====================><8======================= In file included from codec_internal.h:27, from blockmap.c:18: dsp.h:22: conflicting types for `ogg_uint64_t' c:/MinGW/include/ogg/os_types.h:42: previous declaration of `ogg_uint64_t' c:\MinGW\bin\make.exe[2]: *** [libtheora_la-blockmap.lo] Error 1 c:\MinGW\bin\make.exe[2]: Leaving directory `C:/msys/home/Administrator/libtheora-1.0alpha7/lib' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `C:/msys/home/Administrator/libtheora-1.0alpha7' c:\MinGW\bin\make.exe: *** [all] Error 2 ====================><8======================= As far as I understand the type of ulong 64 is redefined in the module "dsp.h", as: typedef unsigned long int ogg_uint64_t; And this is in conflict with the original definition, which we can find in the MINGW\include\ogg\os_types.h: typedef unsigned long long ogg_uint64_t; So, the question is: could anybody help me to understand how to fix it? And what type to leave and what to remove? Or should I write to the library author? I just beleave that there is anybody here, who already tried to compile it... And could I just leave it as it is now and go ahead through other steps? Will the theora be automatically excluded from MPlayer building, or should I make any extra changes in other scripts to exclude it? Thanks.
