What does --arch=x86_64 do ? $ mingw32-make.exe V=1 libavcodec/libavcodec-58.dll mkdir -p libavutil/ mkdir -p libswscale/ mkdir -p libswresample/ mkdir -p libavcodec/ mkdir -p libavformat/ mkdir -p libavfilter/ mkdir -p libavdevice/ mingw32-make: *** No rule to make target 'libavcodec/libavcodec-58.dll'. Stop. Doesn´t work. Then I tried to change : EXTERN_PREFIX="$(EXTERN_PREFIX)" AR="$(AR_CMD)" NM="$(NM_CMD)" $(SRC_PATH)/compat/windows/makedef $(SUBDIR)lib$(NAME).ver $(OBJS) > $$(@:$(SLIBSUF)=.def)` into EXTERN_PREFIX="$(EXTERN_PREFIX)" AR="$(AR_CMD)" NM="$(NM_CMD)" $(SRC_PATH)/compat/windows/makedef $(SUBDIR)lib$(NAME).ver $(SUBDIR)/*.o > $$(@:$(SLIBSUF)=.def) SLIB_CREATE_DEF_CMD into common.mak, but i directly changed it into library.mak by replacing $(SLIB_CREATE_DEF_CMD) by this line. Result : LD libavcodec/avcodec-58.dll C:/msys64-gcc73/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/7.3.0/../../../../x86_64-w64-mingw32/bin/ld.exe: Cannot export av_codec_ffversion: symbol not defined C:/msys64-gcc73/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/7.3.0/../../../../x86_64-w64-mingw32/bin/ld.exe: Cannot export av_codec_get_chroma_intra_matrix: symbol not defined C:/msys64-gcc73/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/7.3.0/../../../../x86_64-w64-mingw32/bin/ld.exe: Cannot export av_codec_get_codec_descriptor: symbol not defined ... And a lot of undefined references.
