Setting Up GNU Step

Message

Evilguru · Post by **Evilguru** » Tue Jul 04, 2006 10:18 am

I am interesting in having a poke at objective C on my Gentoo PC (after liking it on my Mac) and so I did the following:
Added:

Code: Select all

gnustep-base/gnustep-back
gnustep-base/gnustep-base
gnustep-base/gnustep-env
gnustep-base/gnustep-gui
gnustep-base/gnustep-make

To /etc/portage/package.keywords

Emerged: gnustep-base/gnustep-base (which also emerged gnustep-base/gnustep-make) and gnustep-base/gnustep-gui

I am now not sure what I need to do to configure it so that the header files/libraries can be found etc.

Thanks for all of your help.

Please have a look into this thread http://forums.gentoo.org/viewtopic-p-33 ... ml#3350238. That tells quite good what to when you want to install GNUstep on Gentoo. There is a Howto under http://gentoo-wiki.com/HOWTO_GNUstep. You may get additional info there. But try the forum entry first.

Have fun!

Yes - the problem I have is with emerge gnustep-base/gnustep-env is:

Code: Select all

genware Programming # emerge -pv gnustep-env

These are the packages that would be merged, in order:

As you can see, it wants to down-grade my other gnustep packages (~x86) and install an old version of GCC. Is there anyway to stop this madness?

Have you run revdep-rebuild? That should resolve downgrading issues.

Hypnos · Post by **Hypnos** » Thu Jul 06, 2006 4:40 am

Isn't the syntax for /etc/portage/packages.keywords:

Code: Select all

<packagename>  <special keyword>

so it should be

Code: Select all

gnustep-base/gnustep-back ~x86
gnustep-base/gnustep-base ~x86
gnustep-base/gnustep-env ~x86
gnustep-base/gnustep-gui ~x86
gnustep-base/gnustep-make  ~x86

This might be why emerge wants to downgrade everything.

After adding dev-libs/lbffi to /etc/portage/package.keywords I now get:

Code: Select all

fluorine libffi # emerge -pv gnustep-env

These are the packages that would be merged, in order:

[ebuild  N    ] gnustep-base/gnustep-env-0.1.7  USE="doc -debug -profile -verbose" 0 kB

It still wants to downgrade some packages (such as freetype). How can I stop it from wanting to do this?

Does your packages.keywords match what I posted above?

Evilguru · Post by **Evilguru** » Sat Jul 15, 2006 10:45 pm

Yep, all apart from the ~x86 bit, which is deprecated and no longer needed.

Hypnos · Post by **Hypnos** » Sat Jul 15, 2006 11:02 pm

Sorry, I was not aware of the change in the syntax -- you are right.

Hmm, when I duplicate your /etc/portage/packages.keywords, I get the correct behavior. You might try checking that you get the correct behavior for non-GNUstep packages, if you have not done so already.

Hypnos · Post by **Hypnos** » Thu Jul 20, 2006 4:13 am

If the problem really is with GNUstep, it might be that you're using libffi instead of ffcall. ffcall is recommended, and pulls in the latest versions of everything.

Evilguru · Post by **Evilguru** » Sat Jul 22, 2006 1:52 pm

What is the easiest way to do that (change USE flags &c)?

In your USE flags, set "ffcall" and "objc", and unset "libffi"

Then follow my directions here:

(You've probably already done step 0)

Have you confirmed that your packages.keywords works for non-gnustep packages?

Reproducing all your steps on my machine, everything works as expected.

Today I unmerge all of the gnustep packages that I had and then did emerge -pv gnustep-env:

As you can see now it wants to emerge one set, only to seemingly get rid of it! Could the: -gcc-libffi USE flag have anything to do with this?

Thanks for all of your help.

* You haven't answered my question as to whether or not your /etc/portage/packages.keywords works for non-GNUstep ebuilds

* To try to explain this latest behavior, add "--tree" to your emerge commandline options

My guess is that something is b0rked with your system.

Seems that the Gnustep project is shutting down.

lol

Apparently the crack didn't touch the webpages themselves, but an exploit in their server.

coriolan · Post by **coriolan** » Thu Aug 17, 2006 5:33 am

Oh!

Well, glad to see that they did not give up.

For others: the Gnustep website was hacked and there was a notice much like the one OpenDarwin that they are shutting down.
