Question

我尝试使用http://yaafe.sourceforge.net/manual/install.html中的yaafe库。一切都安装好，并在python中正常工作。但是我想使用matlab接口，我尝试使用以下命令编译yaafemex.cpp： mex -v -L/usr/local/yaafe-v0.64/lib -I/usr/local/yaafe-v0.64/include/yaafe-core yaafemex.cpp 它会出现以下错误。有人能给我一些启示吗？

您需要告诉mex库的名称。它应该像

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。（没有引号）

mex c ++ undefined reference
