SPM/SPM12 MEX Compilation on Windows

Compilation of SPM12 on Windows 10

This page describes the compilation of SPM12 MEX files on Windows 10 with MATLAB R2018b (9.5) and MSYS2 MinGW-w64 GCC.

If you use other versions of MATLAB and/or compiler, make sure that they are compatible: Supported compilers

Installation of MSYS2/MinGW-w64

Download and install MSYS2 from:

https://www.msys2.org/

in directory C:\msys64. Then, from MSYS2, type:

pacman -Syu
pacman -Su
pacman -S --needed base-devel mingw-w64-x86_64-toolchain

Configuration of MATLAB compilation environment

Start MATLAB and type:

>> setenv('MW_MINGW64_LOC', 'C:\msys64\mingw64')
>> mex -setup
MEX configured to use 'MinGW64 Compiler (C)' for C language compilation.

Do not worry if there is a warning:

 Warning: The MATLAB C and Fortran API has changed to support MATLAB ...

Compilation

In MSYS2, move to the SPM12 source directory with

$ cd  /c/Documents and Settings/login/Documents/MATLAB/spm12/src

then set the PATH appropriately

$ PATH=/c/Program\ Files/MATLAB/R2018b/bin/win64:${PATH}
$ export MW_MINGW64_LOC=/c/msys64/mingw64/
$ PATH=/c/msys64/mingw64/bin/:${PATH}

and then type the following to start the compilation process

$ make distclean
$ make && make install
$ make external-distclean
$ make external && make external-install

Notes for compilation with MSYS2 for Octave

Install mingw-w64-octave

$ pacman -S mingw64/mingw-w64-x86_64-octave

then start Octave with:

$ /mingw64/bin/octave --gui

and compile with:

$ cd('/c/Documents and Settings/<login>/Documents/MATLAB/spm12/src');
$ system('make distclean PLATFORM=octave');
$ system('make PLATFORM=octave && make install PLATFORM=octave');
$ system('make external-distclean PLATFORM=octave');
$ system('make external PLATFORM=octave && make external-install PLATFORM=octave');
