我尝试使用http://yaafe.sourceforge.net/manual/install.html中的yaafe库。一切都已安装并在python中正常工作。但是，我想使用matlab接口，并尝试使用以下命令编译提供的yaafemex.cpp：mex -v -L/usr/local/yaafe-v0.64/lib -I/usr/local/yaafe-v0.64/include/yaafe-core yaafemex.cpp
并给出以下错误。有人可以给我一些启示吗？

最佳答案
您需要告诉mex库的名称。应该是这样的mex -v -L/usr/local/yaafe-v0.64/lib -I/usr/local/yaafe-v0.64/include/yaafe-core -l"YOUR_LIB_NAME_HERE" yaafemex.cpp
其中“ YOUR_LIB_NAME_HERE”是相应库的名称。 （无引号）
