bat files, for now, but it will bother you about it. MATLAB still temporariily supports legacy. The years have gone by and MATLAB (as of R2014a) has moved to a new XML-based system for configuring MEX files. If you don't want to copy these files around, you can statically link the runtime libraries into your MEX file by adding the following switches: Libraries such as a MEX file created with MinGW-w64 as above may depend on a few DLLs (at runtime): LIBGCC_S_SEH-1.DLL (for the seh exception distributions) and LIBSTDC++-6.DLL, and possibly libwinpthread-1.dll if you chose a pthreads distribution instead of Win32 threads. "x86_64-w64-mingw32-gcc.exe" which won't automatically link the C++ standard library), adjust the link libraries as needed, compiler flags (e.g. If needed, set up the C compiler in a similar manner with a new XML config file specifying the C language, the C compiler frontend (e.g.
#Matlab r2013a support for mingw c compiler windows 7
You can do this in MATLAB (and every time MATLAB starts with a startup.m script in userpath) with setenv, or just once with the Windows properties dialog or the native Windows 7 setx.exe command.īelow is my old way of making an XML file to do the same thing. This is what allows the mex command to locate the compiler. Set (or create) the MINGWROOT environment variable. Grab the latest revision for w64 from Sourceforge (or use the installer to choose the toolchain you want, picking a pthread or Win32 threads version depending on your needs). Pick one, such as MinGW-w64 (64-bit) or TDM-GCC (32-bit and 64-bit options). There is no need for MSYS, cygwin, or any other environment if you plan on compiling in MATLAB with the mex commandĬustomize the XML config file, using this one as a template (details in long version below).ĭownload and extract a MinGW distribution.
