MinGW-w64 Compiler

Choose the destination folder for installation (in my case 'C:mingw-w64x8664-5.3.0-posix-seh-rtv4-rev0') and go to next steps. After installation, to inform the path of the compiler to Matlab, you can write in Matlab command-window, or directly in your m-file the following command. MinGW's official website mingw-w64.org provides various builds, but I maintain my own distro because I demand complete control. (It's a long story, but mingw-w64 forked from mingw.org. Although my distro was based on mingw.org for many years, I now consider mingw-w64 to be the one true MinGW.).

You can use the MinGW-w64 compiler to build MEX files, a MATLAB^® interface to a C++ library, and standalone MATLAB engine and MAT-file applications. For more information, see 'MATLAB Support for MinGW-w64 C/C++ Compiler'.

Download of MinGW Installation Manager (mingw-get) MinGW-Get Version 0.6.3 (Beta) Windows Execute File (mingw-get-setup.exe: 93,184 bytes) will begin shortly. If not so, click mingw-get-setup.exe. Mingw-w64 is an advancement of the original mingw.org project, created to support the GCC compiler on Windows systems. It has forked it in 2007 in order to provide support for 64 bits and new APIs. It has since then gained widespread use and distribution.

Install MinGW-w64 Compiler

To install the compiler, use the Add-Ons menu.

On the MATLAB Home tab, in the Environment section, click Add-Ons > Get Add-Ons.
Search for MinGW or select from Features.

Building `yprime.c` Example

You can test the MinGW^® compiler by building the yprime.c example. Copy the source file to a writable folder.

If you only have the MinGW compiler installed on your system, the mex command automatically chooses MinGW. Go to the next step. However, if you have multiple C or C++ compilers, use mex -setup to choose MinGW.

Build the MEX file.

MATLAB displays a “Building with” message showing what compiler was used to build the MEX file.

Run the function.

MinGW Installation Folder Cannot Contain Space

Do not install MinGW in a location with spaces in the path name. For example, do not use:

Mingw-w64-install.exe Offline Installer

Instead, use:

Updating MEX Files to Use MinGW Compiler

If you have MEX source files built with a different MATLAB-supported compiler, you might need to modify the code to build with the MinGW compiler. For example:

Library (.lib) files generated by Microsoft^® Visual Studio^® are not compatible with MinGW.
Object cleanup is not possible when an exception is thrown using the mexErrMsgIdAndTxt function from C++ MEX files, resulting in memory leak.
An uncaught exception in C++ MEX files compiled with MinGW causes MATLAB to crash.
MEX files with variables containing large amounts of data cannot be compiled, as the compiler runs out of memory.
