Subject: Re: [OMPI users] Can not turn off C++ build.

According to config.log, your icpc is broken -- it won't compile a trivial C++ program. Try it yourself -- try compiling

-----
#include <stdio.h>
#include <iostream>
using namespace std;
int main(int argc, char* argv[]) {
    cout << "Hello, world" << endl;
    return 0;
}

Do you need to set some environment variables before you invoke the Intel compilers?
