What is --without-x option for?

Question

I have a gcc compiler v 4.2.2 with next build options :

$ /opt/eldk-4.2/usr/bin/ppc_6xx-gcc -v
Reading specs from /home/dejovivl/workspace/eldk-4.2/usr/bin/../lib/gcc/powerpc-linux/4.2.2/specs
Target: powerpc-linux

Thread model: posix
gcc version 4.2.2

Most options are easy to find, except for --without-x. So, what is this option for?

The summary of gcc options didn't help, since the option is not listed.

Answer 1

Configure options are not options to gcc. They are given when gcc is built to the configure script. To find out what they mean, check the gcc source documentation.

If --with-x is not there, it doesn't have to mean anything, as autoconf-generated configure scripts can ignore flags.

However, it is listed on http://gcc.gnu.org/install/configure.html -

--with-x

Use the X Window System.
