MATLAB: C++ compiler

c/c++compilermatMATLABmsvc

I was informed on the 'Answers' forum yesterday that the 64 bit version of MATLAB does not ship with a c/c++ compiler. I am currently using msvc but would like to know if there are any other options for compiling a standalone application to create mat files. I am compiling through the MATLAB command: mex('-v', '-f', [matlabroot'\bin\win64\mexopts\msvc100engmatopts.bat'],'C:\…\MatFileCreate2.cpp');

I know that my engmatopts file would have to be changed to use another compiler, but is there another available anywhere?

Thanks

You can reference the list of supported compilers for the current release of MATLAB:

The only supported compilers for 64-bit MATLAB on Windows using MATLAB Compiler are the Microsoft Visual C++ compilers.

icc does not ship with Matlab. LCC ships with some versions of Matlab. It does not, however, apply to any 64 bit version, as LCC is only a 32 bit compiler.

MATLAB: Do I receive an error message regarding the “cl” compiler on the DOS path when compiling and linking engine programs with MATLAB 7.0.4 (R14SP2)

This error message is seen if the environment variable, MSVCDir, does not point to the correct location of the Visual Studio Installation.

To solve the issue, set MSVCDir to the ACTUAL location of your MSVC install as follows:

1. Make a copy of the "msvc71engmatopts.bat" file in the current working directory. Note that the "msvc71engmatopts.bat" file can be found under $MATLABROOT\bin\win32\mexopts\msvc71engmatopts.bat, where $MATLABROOT is the installation directory of MATLAB 7.0.4 (R14SP2). Also note that this file may not exist in those versions of MATLAB which do not support Microsoft Visual Studio .NET 2003.

2. Open the file in a text editor. In line 13, change the "MSVCDir" variable from:

 set MSVCDir=%MSVCDir%

to:

 set MSVCDir=C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7

(where C:\Program Files is the directory that contains Microsoft Visual Studio .NET 2003)

In general, the directory is usually something like:

 C:\Program Files\Microsoft Visual Studio <version>\VC<version>

In some versions of Visual Studio, the "VC" folder does not have a version number. The correct directory will contain a "bin" folder which is where the compiler is located (CL.EXE).
