Compiling with gcc (cont)

Command line options:
  • The default with gcc is not to give you any warnings about potential problems
  • Good practice is to be tough on yourself: 

    prompt$ gcc -Wall -Werror prog.c

    which reports as errors all warnings to anything it finds that is potentially wrong or non ANSI compliant

  • The -o option tells gcc to place the compiled object in the named file rather than a.out 

    prompt$ gcc -o prog prog.c
