在msys2和mingw32上编译ffmpeg——创建ffmpeg_g.exe时出错

我使用MSYS2和MinGW从源代码编译了ffmpeg。在编译过程中成功创建了库文件，当make utility继续构建ffmpeg_g时，我得到了很多未定义的引用。请告诉我编译失败的原因。。。。 提前感谢

已成功生成以下库文件

libavcodec.a
libavdvice.a 
libavfilter.a 
libavformat.a 
libavutil.a 
libpostproc.a
libswresample.a
libswscale.a 

通过使用-d选项和mke编译ffmpeg_g.exe输出时传递的命令

g++ -Llibavcodec -Llibavdevice -Llibavfilter -Llibavformat -Llibavresample -Llibavutil -Llibpostproc -Llibswscale -Llibswresample -Wl,--nxcompat -Wl,--dynamicbase -Wl,--as-needed -Wl,--warn-common -Wl,-rpath-link=libpostproc:libswresample:libswscale:libavfilter:libavdevice:libavformat:libavcodec:libavutil:libavresample  -o ffmpeg_g.exe ffmpeg_opt.o ffmpeg_filter.o ffmpeg.o cmdutils.o  -lavdevice -lavfilter -lavformat -lavcodec -lpostproc -lswresample -lswscale -lavutil -lavicap32 -lpsapi -lole32 -lstrmiids -luuid -lws2_32 -lx264 -lvpx -lvpx -lvpx -lvpx -lvorbisenc -lvorbis -logg -lopenjpeg -lmp3lame -lfdk-aac -lfaac -lbluray -L/mingw32/lib -lass -lm -lharfbuzz -lfontconfig -lexpat -lfreetype -lexpat -lenca -lm -lfribidi -lglib-2.0 -lintl -lws2_32 -lole32 -lwinmm -lshlwapi -lintl -lfreetype -lz -lbz2 -lm -lbz2 -lz -lpsapi -ladvapi32 -lshell32

gcc的输出如下所示

大量未定义的引用，后跟

生成输出

你能把完整的输出发布到pastebin或者是一个要点或者是什么（运行make-V）吗？嗨。。我已将完整输出粘贴到以下链接：好的，现在执行“make-V”PleaseOps的完整输出，我的意思是

make V=1

LOLhi。。对不起，我不明白，我还是一个没有缺点的人。。。我已将make V=1的输出粘贴到：。谢谢你的帮助。。。
