MinGW-w64 Compiler

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".

InstallMinGW-w64 Compiler

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

On the MATLABHometab, in theEnvironment部分中,点击Add-Ons > Get Add-Ons.
Search for MinGW or select fromFeatures.

Building`yprime.c`Example

You can test the MinGW^®compiler by building theyprime.cexample. Copy the source file to a writable folder.

copyfile(fullfile(matlabroot,'extern','examples','mex','yprime.c'),'.','f')

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

mex-setup

Build the MEX file.

mexyprime.c

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

Run the function.

yprime(1,1:4)

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

MinGWInstallation Folder Cannot Contain Space

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

C:\Program Files\mingw-64

Instead, use:

C:\mingw-64

Updating MEX Files to UseMinGWCompiler

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:

库(.lib) files generated byMicrosoft^®Visual Studio^®are not compatible with MinGW.
Object cleanup is not possible when an exception is thrown using themexErrMsgIdAndTxtfunction 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.
