For more complex calculations we have to resort to maths software tools as is the case of this MATLAB, one of the most popular scientific programs among students and engineers all over the world.īut if you've come here with the intention to find out how to download it to your PC, you probably know what it's all about. Use Dependency Walker tool to list them all.Unfortunately, not all maths operations can be carried out by counting with our fingers or turning to a calculator, not even a scientific one. Note: If you are compiling C++ code and you want to distribute the binaries to other people, you might need to also include a couple of DLL files from MinGW which will be dependencies for the compiled MEX-file (stuff like libstdc++). Now we use it to compile a sample MEX-file: > mex -f mexopts_mingw64.bat -v -largeArrayDims "C:\Program Files\MATLAB\R2014a\extern\examples\mex\yprime.c" Set NAME_OUTPUT=-o "%OUTDIR%%MEX_NAME%%MEX_EXT%" Set LINKFLAGS=-shared -L"%LIBLOC%" -L"%MATLAB%\bin\%MW_TARGET_ARCH%" Set LIBLOC=%MATLAB%\extern\lib\%MW_TARGET_ARCH%\microsoft Set COMPFLAGS=-c -m64 -mwin32 -mdll -Wall -DMATLAB_MEX_FILE Here's the link to the latest binaries as of this moment (GNU GCC 4.9.1).Įxtract the 7z archive to some location (preferably without spaces), say C:\MinGW-w64\mingw64.Īdd the bin folder to your PATH environment variable, so something like set PATH=C:\MinGW-w64\mingw64\bin %PATH% but do it system-wide.Ĭreate the following file (feel free to add compiler switches like -std=c++11 if you want C++11 support): mexopts_mingw64.bat off Start by downloading MinGW-w64 compiler toolchain. That said, I have put up a new post since a) MATLAB/MinGW/MEX have all had significant updates since then (not even sure if MinGW is the easiest way out of this mess) b) there is a 64 bit thing (not sure if it's a problem) and c) the "-I" and "-L" options are important. Note, my issue is very similar to this post from 2+ years ago. I am happy to download and edit whatever files are necessary so that I can a) compile MEX files within MATLAB by using the "MEX" command and b) guarantee that "-I" and "-L" instructions will also passed to the MEX compiler. I understand that I might be able to avoid these errors if I use GCC to compile MEX files in MATLAB.
Some of the people that I work with, however, are having trouble compiling them in Windows 7 using the C compiler from the Windows 7.1 SDK. The MEX files compile smoothly in MATLAB 2014a on Mac OS X 10.9 (using "XCode with Clang" as the compiler). I am looking for a simple way to compile Unix MEX files on a Windows 7 computer.
