Validating the C and C++ Compilers

To validate that the C and C++ compilers work as they should, run the following commands to validate that they are working as expected:

if [[ -f dummy-c.c ]]; then
  rm -f dummy-c.c
fi
if [[ -f dummy-c ]]; then
  rm -f dummy-c
fi
cat << EOF > dummy-c.c
#include <stdio.h>
int main() {
  printf("Hello world\n");
  return 0;
}
EOF
/bin/cc dummy-c.c -o dummy-c
echo "Exit code: $?"
if [[ -f dummy-cxx.cxx ]]; then
  rm -f dummy-cxx.cxx
fi
if [[ -f dummy-cxx ]]; then
  rm -f dummy-cxx
fi
cat << EOF > dummy-cxx.cxx
#include <iostream>

using namespace std;

int main() {
  cout << "Hello world" << endl;
  return 0;
}
EOF
/bin/g++ dummy-cxx.cxx -o dummy-cxx
echo "Exit code: $?"

If the exit codes for both tests come back as 0, the compilers are working as expected and the remaining builds should work as they should. If, however, they do not, revert the VM and re-attempt building GCC, and verify that all the flags used are what is proscribed in this guide.
