c++ - mex c++ 未定義参照

Question

http://yaafe.sourceforge.net/manual/install.htmlから yaafe ライブラリを使用しようとしました。すべてがインストールされ、Python で正常に動作します。ただし、matlab インターフェイスを使用したいので、次のコマンドを使用して提供された yaafemex.cpp をコンパイルしようとしまし mex -v -L/usr/local/yaafe-v0.64/lib -I/usr/local/yaafe-v0.64/include/yaafe-core yaafemex.cpp たが、次のエラーが発生します。誰かが私に光を当てることができますか？

ライブラリの名前を mex に伝える必要があります。それは次のようなものでなければなりません

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

ここで、「YOUR_LIB_NAME_HERE」は対応するライブラリの名前です。（引用符なし）
