Nu and Ubuntu linux

[Teunis Peters]

I'm working with ubuntu linux and I've run into a couple of problems
I rather like the look of this - it has a lot of potential. I've noticed from comparison against the 'GNUstep' system though that GNU-style Makefiles are preferred...
perhaps "Makefile.linux" or something like that.

Any suggestions? Any success stories? I'm using the 'git://code.neontology.com/Nu.git' tree if that helps.

Thanks!

Notes follow:

some example sections on GNUstep makefiles:

GS_ROOT = /usr/lib/GNUstep/
. $(GS_ROOT)System/Library/Makefiles/GNUstep.sh
(to set the variables)
and in makefile:
include $(GNUSTEP_MAKEFILES)/common.make
...set variables...
include $(GNUSTEP_MAKEFILES)/application.make

I've been trying to reproduce this configuration while not using the gnustep build process - but I may have to switch to that.

First was added includes -as I've got GNUstep installed. NuFoundation doesn't seem to work for me.

Hi Teunis,

I think that it would be great to get Nu running with GNUstep, but
have no personal experience yet with it (GNUstep). However, if I can
reproduce your environment, I'll work on this, and it probably won't
take much to fix. I've been running Ubuntu 7.10 in a VMware image.
Can you help advise me on how to get the basics of GNUstep in place
for this?

thanks!

Tim

It's all in the "Universe" package selection

apt-get install libfoundation1.0-dev gnustep-devel gnustep-make libgnustep-base-dev gobjc

I'm not sure as yet what other build dependencies are needed. gobjc, libfoundation and gnustep-make are all kind of required.

for rake: apt-get install rake

I haven't done anything odd with the environment - but that might not be all of the dependencies, depending on what Nu requires - but it should be ;)

(for operations: probably libfoundation, gnustep-base and possibly gobjc - I haven't examined it enough as yet)

Thank you
