Question Shell script problems, passing options to gcc


Hi,

I'm trying to create a tiny script that passes command line options to gcc when I'm working with GCC. The script is as follows:

#!/bin/bash
# cmpl - Script to compile .c source files
gcc "$CFLAGS" "$1".c -o "$1".o

This script works when $CFLAGS is only one option, for instance:

"-O2"

but fails whenever a second option is included, such as:

"-O2 -pipe"

giving the message: "cc1: invalid option '-O2 -pipe'

The combination above works when I type it at the command line. I'm confused. Any help would be much appreciated.

Mark

no double quotes, by the looks of your script you seem to think bash variables need to be in double quotes, they dont apart from special cases. you also might want to look into makefiles, a much better way to do this than a script.

Thanks for your help,

I've looked at the thread that you need some help with, but I'm afraid I'm out of my depth.

Sorry I can't return the favour.
