Nu, GNUstep, and Debian Linux

I have an experimental Debian package that contains a Nu interpreter built for Debian Etch (4.0). This Nu is built to use the GNU Objective-C runtime and GNUstep-base, the GNUstep open-source equivalent of Apple’s Foundation classes.

With GNUstep support, “NuFound” (aka libFoundation) support is dropped. GNUstep is actively maintained and adds at least one very important feature (UTF-8 support) that is missing in libFoundation.

All source code changes for this build are now in my Nu github repository and I will soon also add a nuke task to build the Debian package.

Please be aware that this is very new. So far it has only been tested in a VMware image, but because it is based completely on stock Debian components, I think it will hold up well.

A link and more details are below.

Downloading

To download and install the package, run the following in your Debian installation:

tim@debian:~$ wget http://programming.nu/nu-0.3.3-1_i386.deb
--09:58:48--  http://programming.nu/nu-0.3.3-1_i386.deb
           => `nu-0.3.3-1_i386.deb'

If you get messages abut missing dependencies, run the following to resolve them:

tim@debian:~$ sudo apt-get -f install

Then type “nush” and give it a try!
