Re: GNUstep app fails on Ubuntu 16

[Andreas Höschler]

Hi all,

This cairo/back combo is so far unusable for me. I will try libart now ...

apt-get install libart-2.0-dev

cd /usr/src/GNUstep

cd libs-back

./configure --enable-graphics=art

...

## ------- ##

## WARNING ##

## ------- ##

You are about to build the art backend which is deprecated

and likely to be removed in the future.

make

make install

cd ..

I have retried my application under art. When I open one of the problematic forms I now get

and the app fails (hangs). Hmmgh!! Could the problem be related to this

message? My code works on MacOSX and used to work on older GNUstep releases. This of course does not mean much. There could still be a problem that is tolerated by the other two environments. I will try to figure out where this "given negative ..." stuff comes from. However, if this already rings any bells I would be glad to hear your suggestions. 

Thanks,
