How to run resize.cc on Linux?

Hi, I am doing face recognition with ZR model(https://www.ics.uci.edu/~xzhu/face/). Everything works fine in Windows but in Linux I get an error in resize.cc file:

Error using mex
resize.cc: In function ?mxArray* resize(const mxArray*,
const mxArray*)?:
resize.cc:89:43: error: cannot convert ?const size_t* {aka const long unsigned int*}? to ?const int*? in initialization
const int *sdims = mxGetDimensions(mxsrc);
                                           ^
resize.cc:102:73: error: cannot convert ?int*? to ?const size_t* {aka const long unsigned int*}? for argument ?2? to ?mxArray* mxCreateNumericArray(size_t, const size_t*, mxClassID,
mxComplexity)?
mxArray *mxdst = mxCreateNumericArray(3, ddims, mxDOUBLE_CLASS, mxREAL);

What is the reason? How can I fix it?

Answer 1

[Jan]

The solution might follow exactly the error message: define sdims and ddims as size_t:

const size_t *sdims = mxGetDimensions(mxsrc);
size_t *ddims;

Thanks for the answer. I changed that in other two mex files too and it compiled without errors. However, now, anytime my face detector script uses mex files, matlab crashes. Here's the report:

This error was detected while a MEX-file was running. If the MEX-file
is not an official MathWorks function, please examine its source code
for errors. Please consult the External Interfaces Guide for information
on debugging MEX-files.

Why are these mex files not working on Linux?

Answer 2

[Nicole Poltorak]

I managed to solve it with your advice! Thanks!

I used a modified version of your code:

const long unsigned int *sdims = mxGetDimensions(mxsrc);
long unsigned int ddims[3];
