bug#19510: --with-ns won't run on Fedora 21

[Paul Eggert]

On Fedora 21 x86-64, if I configure emacs with "./configure --with-ns 
CFLAGS='-g3 -O2 -DGNUSTEP'" (the -DGNUSTEP is to work around Bug#19507), the 
resulting executable fails with the following diagnostic:

2015-01-04 13:27:06.763 emacs[28811] Did not find correct version of backend 
(libgnustep-back-024.bundle), falling back to std (libgnustep-back.bundle).
2015-01-04 13:27:06.764 emacs[28811] NSApplication.m:304  Assertion failed in 
initialize_gnustep_backend.  Unable to find backend back
./emacs: Uncaught exception NSInternalInconsistencyException, reason: 
NSApplication.m:304  Assertion failed in initialize_gnustep_backend.  Unable to 
find backend back

Sorry, I don't know what those diagnostics mean.  I'm using just the standard 
Fedora 21 installation as far as I know.

It looks like you have installed the wrong backend.

I imagine it was something more complicated than that, as I hadn't installed 
anything other than what Fedora 21 packages.  I had already installed the 
gnustep-gui-devel package but apparently that does not suffice to run GnuStep 
apps.  After installing gnustep-examples the problem went away.  The examples 
themselves aren't needed, but they have prerequisites that apparently supply the 
missing runtime components.  The whole thing is very mysterious, I must say; it 
would be nice if the diagnostics were clearer, but I'm so lost that I don't know 
what they should say.

Anyway, thank for checking, and I am closing the bug.  Bug#19507 still remains 
(it wasn't affected by installing gnustep-examples).

I don't have Fedora 21 installed, but on 20 you had to install gnustep-back separately.
At one time there was two backends you could choose from, but 20 only seems to have one.

Right.
