MinGW is capable of direct-linking a DLL that is, it will create a kind of an import library on the fly when linking. For example, student editions are 32-bit even on 64-bit versions of Windows.

It's not the Windows bitness that matters, but the MATLAB bitness. And I didn't know that MinGW64 exists and works. It's actually quite exciting! I didn't know it's possible. Ok, I fixed the instructions (there are lots of fixes), and (ahem) actually did the thing and ran the result on Matlab - it seems to work for a simple mex file.

def file, or adding "_declspec(dllexport)" before void mexFunction(.)).Ĭrap, its 64 bit :( – Menyh Dec 18 '11 at 21:49 Things which can be done better - instead of -export-all-symbol, only export mexFunction (requires creating another. X86_64-w64-mingw32-c++ -m64 -shared -I"C:\." -DMATLAB_MEX_FILE -o bla.mexw64 -Wl,-export-all-symbols *.cpp libmex.a libmx.a libmat.a libeng.a X86_64-w64-mingw32-dlltool -d f -dllname libmx.dll -l libmx.a relevant function names go here, such as me圎rrMsgTxt, matOpen, etc.Įxecute the following command, to create import libraries: Hint: me圎rrMsgTxt is from libmex.dll, because it starts with "mex".įor every dll you need to export, create a. List the functions you're missing, and, well, guess what dll they're coming from. To solve this problem, you'll have to create an import library which connects with libmex.dll, libmx.dll, libmat.dll and libeng.dll (you might have others, but these are the main ones) This will result in a bunch of linker errors, such as X86_64-w64-mingw32-c++ -m64 -shared -I"C:\Program Files\MATLAB\R2010b\extern\include" -o bla.mexw64 -DMATLAB_MEX_FILE -Wl,-export-all-symbols *.cpp

Understanding how to do this with 32-bit MinGW should be straightforward.Īdd C:\MinGW-64\bin\ to your path. I will therefore show how to use MinGW-w64 instead. Some might say it's a little tedious the first time.įirst things first - what Matlab do you use? if it's 64-bits, MinGW won't help you, because it's 32-bit. mex file using gcc if you have Matlab installed, from the command line. – Chinasaur Dec 9 '13 at 5:04ĮDIT: There seems to be a much better way with MinGW see my other answer. So I added -include uchar.h to the COMPFLAGS and that seemed to fix it. It appears uchar.h is not included properly. Second, I was getting complaint from matrix.h that char16_t was undefined. You have to fix this by going into Matlab's bin directory and editing mex.pl to change a getValidInputLinkLibraries line to getValidInputLinkLibraries(). First I had one of the Matlab versions where linking erroneously gets a getValidInputLinkLibraries added to the end of the command. Thanks very helpful! I ran into two additional issues. Should yield b:\code\m\xw64 (or whatever the current folder is). Mex -v p:\matlab\R2012a\extern\examples\mex\yprime.c Then you can just try doing this in Matlab: Set NAME_OUTPUT=-o "%OUTDIR%%MEX_NAME%%MEX_EXT%"

I'm using the TDM Mingw64 distribution, which I installed in p:\mingw64-tdm. The file below is for 圆4 version of Matlab and Mingw. Why not adjust the mexopts.bat file in your directory? That way you can use the "mex" command transparently to compile anything, as usual in MATLAB, the same as if it was configured by MATLAB using mex -setup.
