GNU C compiler options

GNU C compiler options

[manish.jain]

Hi,

I need to compile my program using GCC. Can I specify all options in a file
and give the file name as an argument to the GCC.

Regards,
Manish

  I guess, you want an Makefile.

gcc does not support reading the command line options from a file.
But you can do this (on Unix or Cygwin):
    gcc `cat gcc-options`

(You actually can control the options passed to gcc in a file by using
a spec file via the -specs option, but this is hard to use correctly
and somewhat unportable between gcc versions.)
