DevOps, CI/CD and Automation

I have downloaded the tar solaris studio file, uncompressed it in a folder in my user's home. I have added the Solaris Tool Collection and enabled it by default.

Now when I try to run this little program:
#include<omp.h>
#include<stdio.h>
#include<unistd.h>

int main(){
omp_set_num_threads(4);
#pragma omp parallel num_threads(4)
{
//omp_get_thread_num();
sleep(8);
}
}

I get this error:

dmake: defaulting to parallel mode.
See the man page dmake(1) for more information on setting up the .dmakerc file.

Any idea?
