使用MEX編譯C++文件

我想使用MEX在MATLAB上編譯C \ C++文件。我先試着mex -setup然後mex xyz.cpp。但我仍然得到錯誤使用MEX編譯C++文件

E:\MATLAB~1\BIN\MEX.PL: Error: Compile of 'xyz.cpp' failed.

當鍵入此命令

mex -v mexDiscreteFlow.cpp BPFlow.cpp Stochastic.cpp

我得到以下輸出

任何人都可以提供一些建議嗎？

嘗試編譯而不運行Matlab中的C++編譯器。這應該可以幫助你隔離問題。 – 2012-07-10 11:06:01

我想你運行'mex -setup'而不是mex-setup，對不對？ – Drodbar 2012-07-10 11:07:39

@drodbar：是的，我會編輯它。 – user671805 2012-07-10 12:04:56

LCC是Ç編譯器附帶Matlab的，但你嘗試編譯C++文件。你需要再次運行mex -setup並選擇一個C++編譯器（但是如果你還沒有編譯器，首先得到一個C++編譯器）

最好在Windows平臺上使用visual studio的編譯器。 – Shai 2013-04-30 05:40:04
