That's because this has nothing to do with GCC. Errors and warnings of
programs are usually sent to the standard error stream (stderr). You
just redirected the standard output (stdout) to some file and hence
there was no "normal" output the file was empty.
Now, actually this depends on the shell you're using -- you should
read its manual. If you happen to use bash, just use
g77 code.f 2> report.txt
to redirect stderr to that file or e.g.
g77 code.f &> report.txt
to redirect both stderr and stdout to that file.
