Platform compatibility

Note: Anyone know how to convert Platform Compatibility HowTOsource into wiki language, so we can work on others' effort?

Following are procedures for installing GNUstep on different Operating Systems.

BSD

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:

 proc                    /proc           procfs  rw              0       0

References: FreeBSD GNUstep ports, Freshports GNUstep

HP/UX

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

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:

 <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

Solaris

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

Windows

SFU

Microsfot's Service For Unix.

Others

LiveCD for Intel

Current version is 0.9.4.2

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 ;)

• • Second step is to use this cross compiler to compile a native compiler for armv5b cpu.

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

• Using Objective-C enalbed gcc to compile gnustep-core,gnustep-* software.
