我已经使用 MSYS(用于 MinGW)构建了 libvpx.a 和标头。当我试图编译一个示例时,会出现很多对 vpx 成员的未定义引用:
g++ -m32 -static -o dist/Debug/MinGW-Windows/test1 build/Debug/MinGW-Windows/main.o -L/D/Libraries/libvpx/ -lvpx
build/Debug/MinGW-Windows/main.o: In function `main':

所有包括制作,lib 已链接...那我做错了什么?
PS:可能链接libvpx.a文件还不够,我还需要源码自带的.c文件(如果是的话,我不明白.a lib文件需要什么)?
