Error using mex

[JavierCoronel]

Hi everyone,

I have this error when compiling on cpu:

Error using mex
MexConv3D-master/.build/_maxpool3d_cpu.o: In function `maxpool3d_cpu::fprop()':
MexConv3D-master/src/_maxpool3d_cpu.cpp:43: reference to `GOMP_parallel_start' not defined
collect2: error: ld returned 1 exit status

Error in make_all>mex_link (line 339)
mex(mopts{:}) ;

Error in make_all (line 286)
 mex_link(opts, objs{i}, mex_dir, flags.link) ;

Error in run (line 96)
evalin('caller', [script ';']);

Could anyone please help me?
