[gentoo-user] Once again - Can't build Blender

[frank]

Hi,
I've posted this former

After the start of the blender bulid (after the sources are unpacked) I
have to (from another shell):

cp /var/tmp/portage/blender-2.41-r1/work/blender/extern/bFTGL/include/*
 /var/tmp/portage/blender-2.41-r1/work/build/linux2/source/blender/ftfont/intern

The build goes well but then:

/usr/lib/gcc/i686-pc-linux-gnu/4.1.1/../../../../i686-pc-linux-gnu/bin/ld: warning: libdirectfb-0.9.so.24, needed by /usr/lib/libSDL.so, not found (try using -rpath or -rpath-link)

  ebuild.sh, line 937:   Called src_compile
  blender-2.41-r1.ebuild, line 105:   Called die

So my quick'n dirty trick copying include files doesn't work
anymore. :-(((((

Why did I rebuild Blender??? Easy! After an ``emgerge -u world'' Blender
didn't find libraries.

Any hint?
Thanks
F.

PS: Blender was the reason to return to Gentoo.

Well, I always say this, but have you tried revdep-rebuild?  That thing
solves most of these types of problems...

Try rebuilding "libsdl" with directfb USE-flag disabled, or re-emerge
'directfb' and then 'libsdl' (with 'directfb' enabled).
Take note - IIRC directfb is build against current linux-sources.

With your last emerge world, did you notice this message when DirectFB 
was emerged?

 * Each DirectFB update in the 0.9.xx series
 * breaks DirectFB related applications.
 * Please run "revdep-rebuild" which can be
 * found by emerging the package 'gentoolkit'.

revdep-rebuild usually finds these breakages, in your case Blender 
depends on libsdl which is looking for libraries that aren't there. I'd 
suspect that a remerge of libsdl will fix it all.

Incidentally, have you considered why you have DirectFB at all? It's a 
layer on top of a frame buffer and has no use in X at all. It's also 
causing endless trouble for me with emerges, but in my case I need it. 
If you have no use for it, remove 'directfb' from your USE followed 
by 'emerge -N world' then 'emerge --depclean' and revdep-rebuild.
