A big shame. Can't really see the benefit of that, since it's freeware
anyway. I'd be happy to fix that one bug, and make a 64bit version

Fortunately Ubuntu has working multiarch, so I could just install all
the libraries it needed side by side to my usual amd64 libs.

No, the problem was with LGEO, not with ldraw. And anyway the problem
is the same on Windows.

But did you get the LGEO parts to work using l3p?
I use them without problems, setting the right flags with l3p.

About l3p not being open-source, well - it's his brainchild, so I
guess he can decide what he wants to do with it.

Yes, with l3p it works just fine.

Do the unofficial parts from
http://www.philohome.com/leoupd/leoupd.htm work for you? I'd need to
do instructions for Mindstorms, so I really need them, but it seems
like importing the file does nothing. I did restart leocad, but it's
no good.

I never tried those...
I'm at work now, but I'll try to test it later tonight (probably
tomorrow for you).

I just tried importing Philo's update and it worked for me. Are you sure you have write permission to the directory where you installed the pieces library?

Are you compiling your own exe? From what version?

Leocad wants to write to /usr/local/share/leocad/? No, my normal user
doesn't have write access there. Is it possible to configure leocad to
use a pieces library from $HOME/.leocad or something like that?

>   Are you compiling your own exe? From what version?

My own binary, yes, but not exe as I'm on linux. I used the svn trunk.

That's probably the problem then, I need to add some error messages.

You can set the environment variable LEOCAD_LIB=<path> or add a -l <path> to the command line to use the library from a different directory.

My own binary, yes, but not exe as I'm on linux. I used the svn trunk.

I knew you were on Linux, just a habit to say exe :)

Seems like permissions were the problem, yes. With -l importing new
pieces works fine. Thanks!

Hopefully this (outdated) update will soon be useless for NXT parts: 
there is a pending BIG update of LDraw official parts (due next week or 
so) that contains all NXT parts!
