Build Environment Running on Fedora Core 4

Build Environment Running on Fedora Core 4

Prerequisites

Firstly, it would be meaningful to know the System Requirements for OpenOffice.org 2 released by the community. It says that

Linux kernel version 2.2.13 or higher, glibc2 version 2.2.0 or higher

The Linux kernel-2.2.13 became available late in 1999. Looking for similar distributions, you would find some:

• Red Hat Linux 6.1 released in October, 2000 comes with kernel-2.2.12.
• Red Hat Linux 6.2 released in April, 2000 comes with kernel-2.2.14.
  • http://en.wikipedia.org/wiki/Red_Hat_Linux
  • http://fedoraproject.org/wiki/History
• Turbolinux Workstation 6.0 released in June, 2000 comes with kernel-2.2.13 and glibc-2.1.2.

Nowadays it is relatively difficult to get such a somewhat antique distribution. So we will need to find an alternative.

Secondarily, refer to Compiler versions used by port maintainers and release engineers to find out what version of tools are used for release engineering.

Choosing a Linux distribution

Then, choose a Linux distribution. There are many distributions currently available. Since the 'solver' seems to be created on the environment firstly prepared in the year of around 2000, some of the distributions can work with it, but others can not.

Fedora Core Distributions

Fedora Core and Fedora distributions are freely available and widely used in the world.

Versions of the packages bundled in the Fedora Core and Fedora distributions

n/a: Not Available

Dependencies

• gcc-3.4.x series does not work with binutils-2.16.x due to gcc's bug
  • http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33938
  • http://www.google.com/search?q=defined+in+discarded+section
• configure of OpenOffice.org 2.3.0 requires ant-1.6.0 or later.

Choice

Fedora Core 4 plus gcc-3.4.1 seems to be the better choice among the Fedora distributions.

Setting up development environment

Setting up a Fedora Core 4 box

1. Visit http://fedoraproject.org/
2. Follow links to find a list of mirror servers.
3. Download core/4/i386/iso/FC4-i386-DVD.iso
4. Install it.
5. Additionally install necessary packages, if needed.

To use yum, you will need to create a directory 'repodata' since FC4-i386-DVD.iso does not have it while an iso image of Fedora 8 does.

mount -o /dev/cdrom /mnt
mkdir /var/tmp/RPMS
cd /var/tmp/RPMS
ln -s /mnt/Fedora/RPMS/* .
createrepo .

To use the repodata, specify a path of the directory in which repodata is.

cd /etc/yum.repos.d
mkdir disabled
mv *.repo disabled
cat > dvd.repo 
[dvd]
name=Fedora 4 Install DVD
baseurl=file:///var/tmp/RPMS
gpgcheck=0
^D
yum list
yum install name_of_package
mv disabled/* . 
mv dvd.repo disabled
umount /mnt

Installing gcc-3.4.1

1. Visit http://gcc.gnu.org/
2. Follow links to find a list of mirror servers.
3. Download releases/gcc-3.4.1/gcc-3.4.1.tar.gz
4. Apply two patches following an article [porting-dev] OOo Linux builds: Hamburg RE switches over to gcc-3.4.1 by Jens-Heiner Rechtien.
   1. enum patch - http://gcc.gnu.org/ml/gcc-patches/2004-07/msg00968.html by Jakub Jelinek
   2. visibility patch - http://www.nedprod.com/programs/gccvisibility.html by Niall Douglas
5. Install it following instructions at gcc-3.4.1/INSTALL/index.html

bunzip2 -dc gcc-3.4.1.tar.bz2 | tar zxf -
cd gcc-3.4.1
patch -p0 < ../Fix_C++_enums_handling_in_build_range_check.patch
patch -p1 < ../GCC3.4.0VisibilityPatch2.diff
mkdir -p build/object
cd build/object
../../configure '--enable-languages=c,c++'
make bootstrap
make install

Here is an example file Fix_C++_enums_handling_in_build_range_check.patch
This example is cited from http://gcc.gnu.org/ml/gcc-patches/2004-07/msg00968.html
and then a portion "--- gcc/fold-const.c.jj" in the first line is intentionally replaced with "--- gcc.original/fold-const"

Installing JDK

1. Visit http://java.sun.com/products/archive/j2se/1.4.1_03/index.html
2. Download SDK of Java 2 Platform, Standard Edition, v 1.4.1_03 (J2SE).
3. Install it.

sh j2sdk-1_4_1_03-linux-i586-rpm.bin
rpm -ivh j2sdk-1_4_1_03-fcs-linux-i586.rpm
