Hi JL3160,
I use OpenSuse, not ubuntu and probably other users you may help better.
For LC 1.0.2 dependencies are QT4, dxflib and muparser, but Irecommend you
update to LC 2.0.0beta1. At this momment is the same as daily build. See:
http://librecad.org/cms/home/installation/linux.htmlFor LC 2.0.0beta1 dependencies are QT4, boost and muparser.
Cheers,
Rallaz
