This also removes configure-os2.tpl.cmd as it is quite meaningless after having it described in more detail in the readme. (cherry picked from commit 28901fb3d124e92951c7a69eaac678bc13924291)

GCC for OS/2
|
|
============
|
|
|
|
This repository contains the GCC source code with the patches needed to build it
|
|
on the eComStation (OS/2) operating system. One day all patches will be merged
|
|
upstream but currently it is more convenient for the developers to track them
|
|
separately.

Build instructions
|
|
------------------
|
|
|
|
These instructions assume you have the RPM/YUM environment installed.
|
|
See http://svn.netlabs.org/rpm for details.
|
|
|
|
1. Install the necessary packages from RPM with:
|
|
|
|
yum install os2-base-fhs ash gcc gcc-wlink gcc-wrc grep gmp-devel mpfr-devel gettext-devel diffutils gawk flex sed
|
|
|
|
2. Make a build directory outside the source tree.
|
|
|
|
3. Change to that directory and run configure & make using the following
|
|
SH script (tailor it to your needs, check also step 4 below):
|
|
|
|
export LANG=C
|
|
|
|
export SHELL=sh
|
|
export CONFIG_SHELL=$SHELL
|
|
export MAKESHELL=$SHELL
|
|
|
|
export PATH=`echo $PATH | sed -e 's@\\\\@/@g'`
|
|
export ac_executable_extensions='.exe'
|
|
|
|
export CFLAGS='-O2 -march=pentium -mtune=pentium4'
|
|
export CXXFLAGS='-O2 -march=pentium -mtune=pentium4'
|
|
export LDFLAGS='-Zomf -Zmap -Zargs-wild -Zhigh-mem -s'
|
|
|
|
# Make sure xgcc will find its own cc1/cc1plus instead of the host ones
|
|
export PATH="<PATH_TO_BUILD>/gcc${PATH:+;$PATH}"
|
|
|
|
# Make sure programs linked with xgcc will find the correct gccXXX.dll
|
|
export BEGINLIBPATH="<PATH_TO_BUILD>/gcc${BEGINLIBPATH:+;$BEGINLIBPATH}"
|
|
|
|
<PATH_TO_SRC>/configure \
|
|
--with-sysroot=/@unixroot \
|
|
--prefix=<PATH_TO_BUILD>/install \
|
|
--enable-shared \
|
|
--enable-languages=c,c++ \
|
|
--with-gnu-as \
|
|
--disable-bootstrap \
|
|
--disable-multilib \
|
|
--disable-libstdcxx-pch \
|
|
--enable-threads
|
|
|
|
make SYSTEM_HEADER_DIR=$UNIXROOT/usr/include
|
|
|
|
make install
|
|
|
|
4. Autoconf is hell.
