I have installed the 32bit architecture stuff. I am sure the brave intrepid Lazarus users have come across this problem and overcome it. Any ideas? ---------------------------------------------------------------------- snorkel · 2014-11-07 17:08 Well, you need those GTK2 deps or it won't work. You could try rebuilding your binary executables with QT instead of GTK2. ---------------------------------------------------------------------- snorkel · 2014-11-07 17:19 You have to fix the held broken packages.
