We've found ways to get it working in linux and in listen servers!
First, you'll need to download
an updated version of the plugin. (Extract these files to gmod9/addons. This download will be removed when we release next ULib.)
For
a listen server (Do not do this if you're running a dedicated!), open up ulib_plugin.vdf in gmod9/addons and replace the text in there with this:
"Plugin"
{
"file" "../../../sourcemods/gmod9/addons/ulib_plugin"
}
And for a linux server, no special steps should be required. (loads automatically).
Have fun everyone!
