Re: Compiled GUI program fails to run

[Fred Kiefer]

Hi,

You seem to prefer unusual setups for your GNUstep environment. Using clang is fine, but why don't you use GNUstep make? That was ay we could be sure you have a properly setup environment. And you are also using the deprecated xlib backend, with the oldest possible font configuration. Why is this the case? The most likely case for the later is that some libraries required to compile back are missing their devel package.

This suggests that something already went wrong when you did compile GNUstep itself. Could you please recompile everything an watch out for messages from the configure script.

Next, don't forget to run the GNUstep.sh script, try to use GNUstep make and report back, what results you are getting then.

Hope this helps,

Fred

Hello,

With the latest from source on Ubuntu 14.04, I get some warnings and a core dump when running a simple GUI program.

address@hidden:~$ clang `gnustep-config --objc-flags` `gnustep-config --objc-libs`  -fobjc-runtime=gnustep -fblocks -lobjc -fobjc-arc -ldispatch -lgnustep-base -lgnustep-gui  guitest.m

./a.out: Uncaught exception NSInvalidArgumentException, reason: Tried to init array with nil object

This program worked previously, so I was wondering if anyone knew what the issue might be.

Thank you,
Patryk
