I've been trying to get FlightGear to run on my Dell Inspiron 5150 (P4, 512MB memory) running Slack 12 with Linux kernel 184.108.40.206 and KDE 3.5.7 but with no luck.
I've tried packages from slacky.eu, I've tried packages from linuxpackages.net, and I've tried compiling by hand. On this last attempt building 0.9.11-pre1, I generally used the Slackbuilds on slacky.eu, but I ran into the exact same problem I've encountered before with some of the packages. This is what I get when I type "fgfs" into a terminal:
Base package check failed ... Found version [none] at: /usr/share/FlightGear
Please upgrade to version: 0.9.11
I've had this error before with some of the prebuild Slack packages. I've searched the web, and posted at LQ in the Slack forum but can't figure this out.
