RE: [Ltib] Building xorg-server; missing dependencies?

[Alexandre Paradis]

Actually, I patched around this problem.  It's too deep for me to find a
solution for it. Perhaps someone else more knowledgeable than me will
run into the same and find a way to fix it.

For people who might run into this, I managed to get Enlightenment and
all dependent packages to build successfully by sym linking /usr/X11R6
to /home/alex/savannah/ltib/rootfs/usr/  (ln -s
/home/alex/savannah/ltib/rootfs/usr/ /usr/X11R6)


Tested working on the board itself.

Thanks for all your help Stuart.

Hi Alex,

Unfortunately I don't have gentoo so can't investigate.

The symlink on your rootfs are expected, so I'm glad you put them back.
It doesn prove (as I'd expect) the actual libraries on the rootfs are
good.

As I said in the earlier email, the key is to figure out where the
absolute refs get set during configure:

 /usr/lib/libX11.so /usr/lib/libXext.so 

these are what's actually screwing up the build.  You need to look at
the build area to see if you can find out where these are set and work
back from there.

One thing you could try possibly is to clone this LTIB run on another
distro (after a distclean) just to see if this is a factor or not.

Regards, Stuart
