Installing GNUstep from pkgsrc is really straight-forward for NetBSD if you're using a recent pkgsrc distribution. 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 terms of pre-requisites, ensure you've got a working X11 environment on your system and preferrably are using WindowMaker as your window manager.
 +
 
 +
'''Build instructions'''
 +
 
 +
To install GNUstep, you need to cd to your pkgsrc tree and then cd to the right package directory, on my system:
 +
 
 +
  cd /usr/pkgsrc
 +
 
 +
then go to the package you wish to install, for example:
 +
 
 +
  cd meta-pkgs/gnustep
 +
 
 +
and issue the command:
 +
 
 +
  make install
 +
 
 +
This command will download source code and whatever dependencies and compile and install them. The version of the meta-packages I used (released with NetBSD 2.0 and called gnustep-1.10.0nb2) installs the following GNUstep components as parts of the meta-package:
 +
 
 +
* gnustep-make-1.10.0
 +
* gnustep-base-1.10.1
 +
* gnustep-ssl-1.10.1
 +
* gnustep-gui-0.9.4
 +
* gnustep-back-0.9.4

 +

This may be overkill - if you don't need all the applications etc, you can install the packages individually.

==== 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 (powerpc and source); he packages a huge ammount of GNUstep packages. Just add this to your sources.list:
 +
<pre>
 +
deb http://www.linuks.mine.nu/debian/ ./ 
 +
deb-src http://www.linuks.mine.nu/debian/ ./
 +
</pre>
 +
 
 +
This repository contains packages made in unstable, so it's possible that the dependencies only are satisfied in unstable systems.

Revision as of 06:50, 5 June 2005

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.

FreeBSD-based Systems

DragonFly

DragonFly is an operating system and environment designed to be the logical continuation of the FreeBSD-4.x OS series.

I have mostly ported GNUstep to DragonFly, I just need to submit patches now for both GNUstep and DragonFly. To know more, you can contact me. Quentin Mathé

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

PicoBSD

PicoBSD is a one floppy version of FreeBSD 3.0-current.

PC-BSD has as its goals to be an easy to install and use desktop OS, which is built on the FreeBSD operating system.

In terms of pre-requisites, ensure you've got a working X11 environment on your system and preferrably are using WindowMaker as your window manager.

To install GNUstep, you need to cd to your pkgsrc tree and then cd to the right package directory, on my system: 

 cd /usr/pkgsrc

  • 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
    • Compile cross-compiler for arm cpu using gcc compiler on debian 3.1 linux.

    • Second step is to use this cross-compiler which generate binaries code for armb cpu to compile a native compiler. This complier can only be run on native machine nslu2 not on Intel linux.

  • Using Objective-C enalbed gcc to compile gnustep-core,gnustep-* software.
    • more strong testing is needed. please add instructon below if you know how to run objective-c's testsuite in crosstool.
