How to compile MEX binary that only works on 64 bit Linux to use it on macOS?

Hello,

I have a compiled MEX binary that only works on 64 bit Linux ( https://github.com/getzlab/MutSig2CV/blob/master/src/str2doubleq.mexa64 ) and I would like to recompile it for my system (macOS Monterey). I have MatLab compiler but I have no idea how to do it as I am fearly new to MatLab. Could anyone please give me any advice, please?

Best regards,

Gabriela

It is not necessary to cross-compile; the GIT repository includes the .cpp source code (and the .c sources needed for different .mex* files.)

Unfortunately the repository does not include a build script.

You probably start by installing XCode -- though possibly you can get away with installing the command line tools, by going into terminal and commanding

xcode-select --install

Then in MATLAB,

mex -setup C++
mex -setup C

then (I suspect)

mex str2doubleq.cpp
mex count_overlaps_fast2.c
mex hist2d_fast.c 
mex projection_1d_convolutions_fast.c

This worked perfectly! Thank you so much, you're a lifesaver!
