install calcHEP on OS X 10.11

Here CalcHEP tries to create a shared library using c-source test.c with the following content

#include<stdlib.h>
double *Q=NULL;
void xxx(void)
{ int i;
  Q=(double*) realloc(Q,10*sizeof(double));
  for(i=0;i<10;i++) Q[i]=0;
}

The command

gcc -fPIC -shared -o test.so test.c

is finished with error code.

Just repeat it and see what compiler writes about it. May be you have some problem with selinux configuration.
Show me, please, error message

Hi,

let's see if I understood it correctly. I created a file test.c with those lines you wrote above as a content. Executed the gcc command you specified gives

test.c:1:19: fatal error: stdlib.h: No such file or directory
 #include<stdlib.h>
                   ^
compilation terminated.

I hope this helps.

Please, ask somebody to help you to install properly gcc on your computer.

Your should have file
 /usr/include/stdlib.h

Also gcc with -v flag

   gcc -v -shared -fPIC -o test.so test.c

should write

#include <...> search starts here:
 /usr/lib/gcc/x86_64-redhat-linux/4.8.3/include
 /usr/local/include
 /usr/include

So, either you have not file /usr/include/stdlib.h or /usr/include is absent on the search list.

I have not idea what could be a reason of it.

I fixed my compilers following http://clang.llvm.org/get_started.html , so installation of calcHEP was finally successful .

Cheers,
