Fsmunoz:

GNUstep fan, my lack of programming skills doesn't prevent me from trying to develop some apps that might be usable (at least in binary form :) ).

[http://home.gna.org/installerapp/ Installer.app] is my main application.

'''Note''': Anyone know how to convert [http://www.gnustep.org/resources/documentation/User/GNUstep/gnustep-howto_toc.html Platform Compatibility HowTO]source into wiki language, so we can work on others' effort?

Following are procedures for installing GNUstep on different Operating Systems.<br>

=== AIX ===

=== BSD ===
==== Darwin ====
===== Intel =====
===== PowerPC =====
==== FreeBSD ====
You can install GNUstep via ''/usr/ports/devel/gnustep''. However, not all required dependancies are installed.

If you install the following in advance, you should be fine:
* wmaker
* libxml2
* libxslt
* libgmp4
* libart_lgpl2
* libaudiofile
* ffcall
* glitz
You may also want to install ''/usr/ports/net/mDNSResponder''.

'''Note''':
There is a bug in libkvm that '''requires''' a mounted ''/proc''. Until this bug is fixed, make sure you have an entry for ''/proc'' in your ''/etc/fstab'':

<pre>
proc /proc procfs rw 0 0
</pre>

==== Mac OS X ====
==== NetBSD ====
==== OpenBSD ====

=== HP/UX ===
We should stay away from HPUX-10.20, it is not supported by HP anymore.

=== Irix ===

=== Linux ===
==== Debian ====
Since Debian "Sarge" you can just say

apt-get install x-window-system-core wmaker gnustep gnustep-devel gnustep-games

to get GNUstep, X11 and Window Maker installed.

But what happen if you are on Debian stable (3.0) release ?

Here is an answer from gnustep irc channel:
<pre>
<fsmunoz> change every occurence of "stable" for "testing"
<fsmunoz> remove the security.debian.org line
<fsmunoz> do apt-get update
<fsmunoz> apt-get dist-upgrade
<fsmunoz> repeat this last one until nothing gets installed or removed.
<fsmunoz> the, replace "testing" with "unstable"
<fsmunoz> then, apt-get update
<fsmunoz> apt-get dist-upgrade
<fsmunoz> repeat, repeat.
<fsmunoz> done
</pre>

The above was a general guide to upgrade from Debian stable to unstable, not exactly the best way to install GNUstep packages. If one doesn't want to upgrade it is possible to simply add the unstable apt lines to the sources.list and specify the distribution when installing the packages, e.g.
<pre>
# apt-get install -t unstable gnumail.app
</pre>

This will probably upgrade some other packages to satisfy dependencies, but will have a much small impact on the system since only the packages on which GNUstep depends will be upgraded.

Yet another way is to add tarzeau's repository; he packages a huge ammount of GNUstep packages. Just add this to your sources.list:
<pre>
deb http://www.linuks.mine.nu/i_debian/ ./
deb-src http://www.linuks.mine.nu/i_debian/ ./
</pre>

This repository contains packages made in unstable, so it's possible that the dependencies only are satisfied in unstable systems.

==== RedHat ====
===== Advance Server 3.0 =====
===== FC 3 =====

==== Slackware ====
==== SuSE ====

=== Solaris ===
http://www.linuks.mine.nu/gnustep/solaris is one package sources to create solaris packages for GNUstep.
==== Intel ====
==== Sparc ====

=== Windows ===
==== Cygwin ====
==== MingW ====
==== SFU ====
Microsfot's Service For Unix.

=== Others ===
==== LiveCD for Intel ====
Current version is 0.9.4.2

Find the instructions to install and the CD itself [http://livecd.gnustep.org/ here]

==== Linksys NSLU2 ====
* First thing need to happen is to gnerate a gcc cross compiler with objc enabled. Current nslu2 supported gcc only has c and c++ enabled when building the crosstool-native package.

** We got the first step done ;)

** Of course more strong testing is needed. please add instructon below if you know how to run objective-c's testsuite in crosstool.
