严重错误C1083：无法打开包含文件：'mexutils.h'：没有此类文件或目录

Question

I would like to compile a c++ file as a mex file in MATLAB namely: "mexLasso.cpp".

These are the steps I take and I get the following error. What is the problem?

1. Put the files "mexLasso.cpp" and "mexutils.h" in a folder.

2. Set the compiler:

 mex -setup C++ 

I recieve:

MEX configured to use 'Microsoft Visual C++ 2013 Professional' for C++ language compilation.

3. Run the command:

mex C:\...\mexLasso.cpp

I recieve the following error:

Error using mex
mexLasso.cpp
C:\...\mexLasso.cpp(33) : fatal error C1083: Cannot
open include file: 'mexutils.h': No such file or directory

Can somebody help us what we are missing?

Answer 1

From the mex command line tool reference , there is an argument for adding include paths:

-Ipathname Adds pathname to the list of folders to search for #include files.
Do not add a space between I and pathname.

Like this:

mex -v -IC:\path\to\mexutils_h\ mexLasso.cpp

Note that with -I you are not specifying the header, you are specifying a path containing one or more header files.

Thanks for your comments. I think the besy way to solve my problem is to install SPAMS in my machine and successfully compile it. I have posted the steps I take in this post :

Can I have your opinion there. Sorry for duplicated message, only for relevancy and importance of the discussed topic.

Many thanks.
