C++ mex c++；符号未找到

我试着使用yaafe图书馆。所有内容都已安装并在python中正常工作。但是，我希望使用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

它给出了以下错误。谁能给我点启示吗

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“你的名字”yaafemex.cpp

其中“你的名字”是o的名字
