Good Morning.

My profile should be amd64 multilib:
profiles = /var/paludis/repositories/gentoo/profiles/default/linux/amd64/10.0/desktop/gnome

Also I have multilib useflag set, however:

These are the actions I will take, in order:

r media-libs/glu:0::gentoo 9.0.0 to ::installed replacing 9.0.0
(-multilib) -static-libs build_options: symbols=split -optional_tests -trace work=tidyup
Reasons: target, virtual/glu-9.0:0::installed


Why is multilib disabled and how can I enable it please? Would love to have OpenGL for 32bit.

Thank you and best regards

are,

Your profile is a multilib profile. The (-multilib) USE flag on media-libs/glu means that multilib support is forced off for the glu package.
If will be off for a reason e.g. its broken in some way.

If you really really want to turn on the multilib there, read up on why its forced off in the first place.
Then read
Code:
man portage
to discover how to force USE flags if you still want to try it.

Code:

  20 Sep 2012; Chí-Thanh Christopher Nguyễn <chithanh@gentoo.org>
  +features/multilib/package.use.mask, base/package.use.force,
  base/package.use.mask:
  Move media-libs/glu multilib mask to multilib profile, bug #435622.

  19 Sep 2012; Matt Turner <mattst88@gentoo.org> package.mask:
  Remove mask on glu and mesa now that the multilib USE flag has been forced
  off and masked.


I do not understand all that.

are,

The problem is documented in bug #435622.

The rest of the comments relate to changes to the way that the multilib version of glu is masked.

The bug says
bugs:
media-libs/glu-9.0.0[multlilib] fails to compile without app-emulation/emul-linux-x86-opengl

So, can you
Code:
emerge -1 app-emulation/emul-linux-x86-opengl
or does that fail too?

Neddy, first of all, thank you for kind help!

This is exactly, where all that mess begins. What would I like to achieve: 32bit OpenGL for wine 32bit binary blobs.

Problem 1) When I use app-emulation/emul-linux-x86-opengl::gentoo there is the error on missing 32bit libstdc. So I tried to work around using FireBurn Overlay.

then Problem 2) arrives, which is on missing 32bit libGLU. So I tried to work around using a multilib libGLU.

are,

I don't think there is an easy answer or the devs would have fixed the problem, not said you cant have 32 bit OpenGl.

Is dual boot, with a x86 install an option?
A 32 bit chroot may work but I can see issues with your native install and chroot fighting over the graphics card.

Hi

If you're still using the FireBurn overlay update it and re-emerge glu

This is just a quick hack removing the check on the multilib flag - as I can't seem to force override it from my overlay - and also removing the block on emul-linux-x86-opengl

Let me know if you have any issues

You, Sir, are my Hero! It works!
Now I only wonder why it takes an overlay to get multilib mesa/wine -- but damn, I am glad that it is there!

Thank you so much!
