for -output to work. If this environment is not set, the compiler default is to

use the name of the first program in the command line. Even if this is set, it

can be overridden by specifying the

mex -output switch.

Linking DLLs to MEX-Files

To link a DLL to a MEX-file, list the DLL’s .lib file on the command line.

Versioning MEX-Files

The mex script can build your MEX-file with a resource file that contains

versioning and other essential information. The resource file is called

mexversion.rc and resides in the extern\include directory. To support

versioning, there are two new commands in the options files,

RC_COMPILER and

RC_LINKER, to provide the resource compiler and linker commands. It is

assumed that:

•If a compiler command is given, the compiled resource will be linked into the

MEX-file using the standard link command.

•If a linker command is given, the resource file will be linked to the MEX-file

after it is built using that command.

Compiling MEX-Files with the Microsoft Visual C++ IDE

Note This section provides information on how to compile MEX-files in the

Microsoft Visual C++ (MSVC) IDE; it is not totally inclusive. This section

assumes that you know how to use the IDE. If you need more information on

using the MSVC IDE, refer to the corresponding Microsoft documentation.

To build MEX-files with the Microsoft Visual C++ integrated development

environment:

1 Create a project and insert your MEX source and mexversion.rc into it.

2 Create a .DEF file to export the MEX entry point. For example

LIBRARY MYFILE.DLL

EXPORTS mexFunction

<-- for a C MEX-file

EXPORTS MEXFUNCTION@16 <-- for a Fortran MEX-file
