[gentoo-user] emerge swt failed: cannot find -lGL

[Iain Buchanan]

Hi all,

I was just performing a routing update recently, and swt failed with
this error:

now, I've had "cannot find -l<blah> before, and a revdep-rebuild or
something usually fixes it.  In this case however, I couldn't get around
it.

I have been swapping between xorg's x11-drm radeon driver, and ATI's
fglrx driver recently - but I've used eselect correctly - I'm now using
the x11-drm driver.

I don't know what to look at next - any hints?
thanks,

I worked around it by doing this:
$ cd /usr/lib
$ sudo ln -s /usr/lib/opengl/ati/lib/libGL.so

but I don't know that this is the right thing to do - how do I tell if
it actually works like this?

$ sudo eselect opengl set ati
Switching to ati OpenGL interface... done

$ readlink /usr/lib/libGL.so
/usr/lib/opengl/ati/lib/libGL.so

looks fine.

$ sudo eselect opengl set xorg-x11
Switching to xorg-x11 OpenGL interface... done

$ readlink /usr/lib/libGL.so
$ <nothing returned>

looks wrong!

I did a bit of snooping, and found that libGL.so comes from mesa, so I
re-merged mesa (media-libs/mesa-6.5.1-r1) and it seems to be working
again:

$ readlink /usr/lib/libGL.so
/usr/lib/opengl/xorg-x11/lib/libGL.so

now, can googleearth work with mesa? it seems to lock-up at the splash
screen...

thanks!
