Successful build of gcc-3.0.4 on hppa2.0-hp-hpux10.20 and

["Martin Gansser" <mgansser at ngi dot de>]

Compile gcc-3.0.4 on hp-ux 10.20 and hp-ux 11.00 with gcc-3.0.1

download gcc-core and gcc-g++ from the gcc site

ftp://ftp.gnu.org/gnu/gcc/gcc-3.0.4/gcc-core-3.0.4.tar.gz
ftp://ftp.gnu.org/gnu/gcc/gcc-3.0.4/gcc-g++-3.0.4.tar.gz

be sure that the following GNU programs will be used:
====================================

# which as sed ld
/opt/binutils/bin/as        # GNU as Version 2.11.2
/opt/sed/bin/sed            # GNU Stream Editor Version 3.02
/usr/bin/ld                 # HP Link Loader


Environmental variable changes prior to building gcc:
===================================

Put binutils binary directory at the front of your PATH:
export PATH=/opt/binutils/bin:$PATH

If you're using GNU sed, put the sed binary dir in the front of your PATH:
export PATH=/opt/sed/bin:$PATH

If you're using gmake (recommended - optional with this release, will be
mandatory with future releases), then put the gmake binary in the front of

your PATH:
export PATH=/opt/make/bin:$PATH



Changes made to configure files:
======================

* configure:
- remove all -g in CFLAGS=${CFLAGS-"-O2"}

* gcc/Makefile.in:
- Remove all references to -g and -g1 - we don't need debugging flags.

** Remove the -g. Size should decrease.
-g is "add debug symbols". Remove that and the binary will significantly
reduce in size. Anyway the "strip" command will also do that AFTER build.
But I suggest just removing the -g if not in debug mode.
