cannot build mex files using MinGW

I have configured MinGW using mex -setup but cannot seem to succesfully build files. I am using Matlab R2018a with Windows 10.

Trying:

mex('-R2018a','-O', 'CFLAGS="\$CFLAGS -fopenmp"', '-O','LDFLAGS="\$LDFLAGS
-fopenmp"',[path,'private/get_from_3D_projection_mex.cpp'], '-output', [path,
'private/get_from_3D_projection_mex'])

and I get an error:

Error using mex
g++: error: \-fexceptions: No such file or directory

Trying this solution did not work for me https://github.com/cjlin1/libsvm/issues/55

mex('-R2018a','-O', 'COMPFLAGS="\$COMPFLAGS -fopenmp"', '-O','LDFLAGS="\$LDFLAGS
-fopenmp"',[path,'private/get_from_3D_projection_mex.cpp'], '-output', [path,
'private/get_from_3D_projection_mex'])

Then I have:

Error using mex
D:\matl\cSAXS_matlab_base_package\+utils\private\get_from_3D_projection_mex.cpp:76:25: fatal error:
sys/sysinfo.h: No such file or directory
#include <sys/sysinfo.h>

Also trying to build it with VS 2015 I get the latter error...

Any ideas? thanks in advance!

I do not know why you have those two \ in the mex call.

This is how it was written when I downloaded the files. I get the same error with and without them...

Seems these files were written for Linux.

I commented out the line

#include <sys/sysinfo.h>

in all the mex cpp files.

Then included line

#include <windows.h>

also used the mex call

mex('-R2018a','-O', 'COMPFLAGS="$COMPFLAGS -fopenmp"', '-O','LDFLAGS="$LDFLAGS
-fopenmp"',[path,'private/get_from_3D_projection_mex.cpp'], '-output', [path,
'private/get_from_3D_projection_mex'])

with CFLAGS changed to COMPFLAGS and without the \ characters.
