= Configuring MATLAB with GNU C++ compiler (g++) from Cygwin =

 * Install a Cygwin environment (see http://www.cygwin.com). You need at least the following packages: gcc, gcc-g++, gcc-mingw, gcc-mingw-g++
 * Copy the file {{{mexopts.bat}}} in {{{c:\Documents and Settings\<User name>\Application Data\MathWorks\MATLAB\<release number>\}}}. This file comes with your Dynare installation (in {{{c:\dynare\<Dynare version>}}}). If you don't have it in your distribution, you can pick it [[https://www.dynare.org/trac/browser/windows/mexopts.bat|here in the Git repository]].		  * Install a Cygwin environment (see http://www.cygwin.com). If your MATLAB is 32-bit, you need the "mingw64-i686-gcc" package. If your MATLAB is 64-bit, you need the "mingw64-x86_64-gcc" package.
 * The configuration file is called [[https://www.dynare.org/trac/browser/windows/mexopts-win32.bat|mexopts-win32.bat]] for MATLAB 32-bit, and [[https://www.dynare.org/trac/browser/windows/mexopts-win64.bat|mexopts-win64.bat]] for MATLAB 64-bit (these files are also distributed in recent packages of Dynare)
 * Rename the configuration file to {{{mexopts.bat}}}, and copy it to {{{c:\Documents and Settings\<User name>\Application Data\MathWorks\MATLAB\<release number>\}}}.

This page briefly documents how to configure MATLAB for Windows when a MEX compilation environment is required. Under Linux and MacOS, this configuration step is not necessary, because these operating systems already come with a working compilation environment (using g++).

Two compilers are currently supported: GNU C++ compiler (g++) from Cygwin, and Microsoft Visual C++ (MSVC).

With Dynare, you need a working MEX compilation environment in two cases:

  • you need to recompile Dynare MEX files, without using Dynare build system

  • you want to use the USE_DLL option of model, or the k_order_solver option of stoch_simul. In that case, you need to tell Dynare which compiler you are using:

    • if you are using Cygwin, type at the MATLAB prompt: 
      dynare modfilename cygwin
    • if you are using Microsoft Visual C++: 
      dynare modfilename msvc

Configuring MATLAB with GNU C compiler (gcc) from Cygwin

  • Install a Cygwin environment (see http://www.cygwin.com). If your MATLAB is 32-bit, you need the "mingw64-i686-gcc" package. If your MATLAB is 64-bit, you need the "mingw64-x86_64-gcc" package.

  • The configuration file is called mexopts-win32.bat for MATLAB 32-bit, and mexopts-win64.bat for MATLAB 64-bit (these files are also distributed in recent packages of Dynare)

  • Rename the configuration file to mexopts.bat, and copy it to c:\Documents and Settings\<User name>\Application Data\MathWorks\MATLAB\<release number>\.

  • Note that if you installed Cygwin in a non-standard directory (i.e. elsewhere than C:\CYGWIN), you need to edit the mexopts.bat and change the set PATH=... line accordingly.

Configuring MATLAB with Microsoft Visual C++ (MSVC)

The following should work with recent versions of MATLAB:
