Re: Trying to build GNUstep from git repo and clang-9 on Raspbian Buster (10.4)

[Patrick Cardona]

Hi Johannes,
Hi All,

I first made a backup of ~/GNUstep so I started with a fresh new one to avoid 
conflicts with the previous install...
Behalf the script by Patryck Laurent (great job !), pointed out by Johannes, I 
was able to build gnustep from github repo 
with clang-7 on my raspbian 10 (Buster). Every thing was well made. So the 
GNustep runtime is now 1.9.
I build also some apps from gap, GNUMail and so on... I am writing this message 
within GNUMail. ;-)
I installed every new build app with the 'sudo -E' parameter. All worked fine.

But I am facing something curious. I cannot start GWorkspace or Terminal from 
then Run panel within wmaker,
neither from the autostart.
I must first run Xterm, where .bashrc is read, and then I can finally launch 
GWorkspace from there.

I guess something is missing when the X session is loading, but I could not 
find what.

Last precision : The wmaker session is started from SLIM X login.

Regards,
