Mingw Mac Download

Download the installer for MinGW from here: MinGW Installer. The instructions on this page refer to version 7.1.0, build revision 1 of the MinGW tools. This is an older version than what we are currently using. As of September, 2019, the version that we are using is 8.1.0, build revision 0. The build2-install-mingw script downloads and installs (into the same directory as build2) a minimal MinGW GCC distribution that is then used to compile build2. If you would prefer to use your own MinGW GCC, see the alternative installation methods below.

MinGW-w64 Compiler

Mingw Make Download

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'.

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.

For more information, see Troubleshooting and Limitations Compiling C/C++ MEX Files with MinGW-w64.

MinGW Installation Folder Cannot Contain Space

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

Instead, use:

Updating MEX Files to Use MinGW Compiler

If you have MEX source files built with a different compiler that MATLAB supports, 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.
