Hello
I was trying to compile a mex file and I got the following error
>> mex -setup
MEX configured to use 'MinGW64 Compiler (C)' for C language compilation.
To choose a different language, select one from the following:
mex -setup C++
mex -setup FORTRAN
>> compileSparseCoLO
Compiling Libraries...Building with 'MinGW64 Compiler (C++)'.
Error using mex
In file included from
C:\Users\Abd-PC\Downloads\SparseCoLO112\SparseCoLO112\mex\ccputime.cpp:26:0:
C:\Users\Abd-PC\Downloads\SparseCoLO112\SparseCoLO112\mex\ccputime.h:28:23: fatal error:
sys/times.h: No such file or directory
#include <sys/times.h>
^
compilation terminated.
Error in compileSparseCoLO (line 81)
eval(command);
I'm not sure where is the problem and how to solve it. I would appreiate your help.

Upon usng this line:
MexFlags = ' -O -I"C:\Users\Abd-PC\Downloads\SparseCoLO112\SparseCoLO112" -L"C:\Users\Abd-PC\Downloads\SparseCoLO112\SparseCoLO112\sys" -ltime';
I have received the following error
>> compileSparseCoLO
Current directory is = C:\Users\Abd-PC\Downloads\SparseCoLO112\SparseCoLO112\mex
Cannot find sub-directory "mex"
Execute this script at the top directory of SparseCoLO
>> compileSparseCoLO
Compiling Libraries...Error using mex
MEX cannot find library 'time', specified with the -l option.
MEX searched for a file with one of the following names:
libtime.a
time.lib
libtime.lib
Verify the library name is correct. If the library is not
on the existing path, specify the path with the -L option.
Error in compileSparseCoLO (line 81)
eval(command);
And upon using this line
MexFlags = ' -O -I"C:\Users\Abd-PC\Downloads\SparseCoLO112\SparseCoLO112" "C:\Users\Abd-PC\Downloads\SparseCoLO112\SparseCoLO112\sys\time.obj"';
I received this following error
>> compileSparseCoLO
Compiling Libraries...Building with 'MinGW64 Compiler (C++)'.
MEX completed successfully.

Error in compileSparseCoLO (line 93)

I'm not sure what to do next?

I have installed Microsoft Visual C++ 2019 and used it to compile the mex file, I got the following error
>> compileSparseCoLO
Compiling Libraries...Building with 'MinGW64 Compiler (C++)'.
MEX completed successfully.
done
Compiling mexForestConvert.cpp...Building with 'Microsoft Visual C++ 2019 (C)'.
Error using mex
LINK : error LNK2001: unresolved external symbol mexFunction
ccputime.lib : fatal error LNK1120: 1 unresolved externals
I would appreciate your help.
