luajit reports wrong paths #10662

Open Begasus opened 1 week ago

Looking into https://github.com/haikuports/haikuports/issues/8874 This revealed that luajit has the same problems when called from Terminal:

You can see that it's looking in .self, where it would never find external installed packages/rocks.

jmairboeck commented 1 week ago

If I understood it correctly, .self is just a symlink to where the package is installed, so normally /boot/system, but it could be /boot/home/config when installed as a user package. So it should work just fine.

Or did I misunderstand how these links work?

FractalU commented 1 week ago

My guess is that .self is just a symlink to /boot/system. I tested with .self of both Lua 5.4 and Luajit 2.1. The installed Lua packages in /boot/home/config/non-packaged aren't in .self/non-packaged.

Hacked around a bit, so far I'm getting this atm:

Think I'm going to leave it like this for some time, patch seem OK, patch probably not so. :)
