OVERVIEW: There are occasions when you may not want to compile Mozilla on your PlayStation 2 - especially because of the large size of the source tree (14,000+ source files!), or because your PlayStation 2 is not available (i.e. you want to finish your game!) This Mini-HOWTO will show you how to set up a cross compilation environment to allow you to build Mozilla for the PlayStation 2 in a Red Hat 8.0 Intel environment.
BEFORE YOU BEGIN: You will need to have your PlayStation 2 Linux disc 2 available, and a DVD ROM drive on your Red Hat computer. If you don't have a DVD ROM drive available, you will have to start NFSD on your PlayStation 2 and export disc 2. (Don't worry - I'll explain this when we get there.) This means that you will have to have a network connection between your PlayStation 2 and your Red Hat Linux box.
INSTRUCTIONS: The first thing to do is decide on the location of the cross compilation environment on your Red Hat Linux box. I used the directory /usr/mipsEEel-linux for this walkthrough. I strongly urge you to follow this as well - there are some scripts that depend on this structure.
Regardless if you follow my advice or not, it's important to decide the location early - it has to stay consistent during this whole process!
Then, follow these steps on your Red Hat Intel Linux system:
#!/bin/sh
PATH2RPMS=/mnt/cdrom/SCEI/RPMS
xtarget_arch=mipsEEel-linux
cd /usr/${xtarget_arch}/${xtarget_arch}
for r in ${PATH2RPMS}/*.rpm; do
rpm2cpio $r | cpio -ivd
done
chmod -R 755 /usr/${xtarget_arch}/${xtarget_arch}
ln -s usr/include sys-include
(cd usr/src && ln -sf linux-2.2.1_ps2 linux)
(cd lib && ln -s ../usr/lib/*.o .)
# modify various build -config scripts
perl -i.bak -pe "s/\/usr/\/usr\/${xtarget_arch}\/${xtarget_arch}\/usr/g" usr/bin/{glib,gtk,libIDL,orbit}-config usr/lib/libc.so
perl -i.bak -pe "s/\/lib\/libc.so.6/\/usr\/${xtarget_arch}\/${xtarget_arch}\/lib\/libc.so.6/g" usr/lib/libc.so
rm -f usr/bin/{glib,gtk,libIDL,orbit}-config.bak usr/lib/libc.so.bak
NOTE: This script assumes that you created the /usr/mipsEEel-linux/mipsEEel-linux
directory as outlined above. If you've put the directory somewhere else, you'll have to change
the script (which is beyond the scope of this mini-HOWTO!) At this point, your cross compiler should be working. You can try building Mozilla if you'd like. If you've never built Mozilla before, there are instructions at their web page: http://www.mozilla.org/build/
Don't forget! You will need to make sure /usr/mipsEEel-linux/bin is in your path before you do any cross compiling!!! (export PATH=$PATH:/usr/mipsEEel-linux/bin)
You will also have to pass some extra compiler directives to cross compile. Generally, you pass --target=mipsEEel-linux and --prefix=/usr/mipsEEel-linux to your ./configure script, but you'll have to check with the documentation for the application you're cross compiling.
For cross-compiling Mozilla, the easiest way is by using .mozconfig. .mozconfig is a simple script file that is placed in your home directory. (i.e. ~/.mozconfig)
Here's an example .mozconfig that I've used:
# sh # Build configuration script # # See http://www.mozilla.org/build/unix.html for build instructions. # CROSS_COMPILE=1 GLIB_CONFIG=/usr/mipsEEel-linux/mipsEEel-linux/usr/bin/glib-config GTK_CONFIG=/usr/mipsEEel-linux/mipsEEel-linux/usr/bin/gtk-config LIBIDL_CONFIG=/usr/mipsEEel-linux/mipsEEel-linux/usr/bin/libIDL-config HOST_LIBIDL_CONFIG=/usr/bin/libIDL-config LIBS=-lc ac_add_options --prefix=/usr/mipsEEel-linux ac_add_options --target=mipsEEel-linux ac_add_options --x-includes=/usr/mipsEEel-linux/mipsEEel-linux/usr/X11R6/include ac_add_options --x-libraries=/usr/mipsEEel-linux/mipsEEel-linux/usr/X11R6/lib # Options for 'configure' (same as command-line options). # all are listed so that one can manually tweak this config file. #ac_add_options --enable-mathml #ac_add_options --enable-svg #ac_add_options --enable-extensions #ac_add_options --enable-crypto #ac_add_options --enable-logrefcnt #ac_add_options --without-system-nspr #ac_add_options --without-system-zlib #ac_add_options --without-system-jpeg #ac_add_options --without-system-png #ac_add_options --without-system-mng # Paul's options ac_add_options --disable-tests ac_add_options --disable-debug ac_add_options --enable-optimize ac_add_options --without-system-nspr ac_add_options --without-system-zlib ac_add_options --without-system-jpeg ac_add_options --without-system-png ac_add_options --without-system-mng #ac_add_options --enable-crypto #comment to disable PSM/SSL support ac_add_options --disable-freetype2

APPENDIX: Using NFS on your PlayStation 2 to allow your PC to access Disc 2 of PlayStation 2 Linux
You will need to network the two boxes together. Each box should have a unique IP address. For the purpose of this example, we will use 10.0.0.1 for the PlayStation 2 and 10.0.0.2 for the Red Hat box.
Sharing the disc from your PlayStation 2:
/mnt/cdrom (ro,insecure)
Connecting your RedHat box to the PlayStation 2:
Now, you should be able to follow the steps above, substituting /mnt/ps2 for /mnt/cdrom.
Example
rpm2cpio /mnt/cdrom/SRPMS/binutils-2.9EE-3a.src.rpm | cpio -ivd
becomes
rpm2cpio /mnt/ps2/SRPMS/binutils-2.9EE-3a.src.rpm | cpio -ivd
When you're done, you'll need to basically perform the reverse of the steps outlined above:
Disconnect the share on the PC:
Stop NFS on the PlayStation 2:
