Title: Better error message when compilation fails

1. The g++ error message is now displayed in the exception text rather
than hidden before the file content is printed (which made it very hard
to notice).

2. If the call to Popen fails for some reason (e.g. because g++ is not
found), the command line is printed to stderr so that the user has a
better idea of what the problem may be.
