Platform compatibility

Following are procedures for installing GNUstep on different Operating Systems.


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: 

 proc                    /proc           procfs  rw              0       0

Mac OS X

NetBSD

Building GNUstep from source is fairly straight-forward for NetBSD 1.6 and 2.0: it is suggested however to upgrade to 2.0 if possible. NetBSD/i386 has no known problems right now, however there are reports of crashout problems for gdomap on NetBSD/sparc which may be related to ffi/ffcall issues.

In general, it's easier to install dependency packages from pkgsrc rather than downloading the sources and tweaking them to build and install.

Prerequisites

It is assumed that you've got a basic X-windows configuration sorted out if you are intending to use the GNUstep GUI. Right now the WindowMaker window manager is recommended.

To get the dependency packages installed, cd to your pkgsrc tree and cd to the right package directories, on my system: 

 cd /usr/pkgsrc

then go to the package you wish to install, for example: 

 cd devel/gmake

and issue the command: 

 make install

This command will download source code and even dependencies on dependencies and compile and install them. Move back to the pkgsrc directory and do this again until all the packages are installed.

The dependency packages are:

  • devel/gmake
  • wm/windowmaker
  • graphics/jpeg
  • graphics/png
  • graphics/tiff
  • devel/ffcall OR devel/libffi
  • textproc/libxml2
  • devel/pth (only for NetBSD 1.6)

Build instructions

OpenBSD

HP/UX

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: 

 <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

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. 

# apt-get install -t unstable gnumail.app

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: 

deb http://www.linuks.mine.nu/i_debian/ ./   
deb-src http://www.linuks.mine.nu/i_debian/ ./

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

  • 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.
  • check out unslung source using follow command.

cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/nslu co unslung

  • add in objc as language need to be enabled.

perl -pi -e 's!^GCC_LANGUAGES=.*!GCC_LANGUAGES="c,c++,objc"!' toolchain/crosstool/nslu2-cross335.sh

perl -pi -e 's!^GCC_LANGUAGES=.*!GCC_LANGUAGES="c,c++,objc"!' sources/crosstool-native/nslu2-native335.sh

    • 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.
