Hi, Yan
I've spent several hours trying to reinstall again and again with
clang, objc2, blocks and so on.
And yes, it's a real pain. But I've got now something that seems to be
finally running.
First of all, regarding your initial question on adding the 386
architecture on debian Jessie ; yes it's mandatory.
Without it, gui apps will segfault in Debian Jessie, due to something
in libobjc.
I've seen on
http://wiki.gnustep.org/index.php/GNUstep_under_Ubuntu_Linux that this
option was set in the "ubuntu 1404 " section but not in the "ubuntu
1604" one.
I've reworked my script and I've splitted it in two parts (one for
installing the dependancies, the other for compilation).
They work as is.
Maybe your problem for now is that libobjc isn't in a place where
gnustep can find it. I remembered that sometimes ago, it wasn't
installed in /usr/GNUstep/Local/Library/Libraries and my compiler
didn't find it. I just picked the files in /usr/local and put them at
that place and everything worked.
But I didn't have this problem today : everything is at his place and
run.
You can try them in a clean jessie install to avoid some common
problems with libraries mismatched or still installed.
Final note : in the script, I didn't add "export CC=clang" and
"export CXX=clang++" to bashrc so you will need to pass this option
each time you compile some other program with gnustep.
Cheers,
Bertrand
