Re: Illegal instruction when running plmerge or a built app

[Eric Wasylishen]

Hi Alister,

The illegal instruction in that backtrace is in the art graphics library 
backend of GNUstep, which is more or less deprecated / unmaintained. First 
thing I would try is installing cairo and re-run ./configure for your SVN 
checkout of gnustep-back - it should automatically detect and use cairo. Next 
make and install gnustep-back, and see if that fixes the problem.

Cheers,
Eric
