multilib-overlay

Wow, you guys just made my day!
This is exactly what I was looking for today, after having horrible issues with current emul packages.

Trying your overlay atm.

First I had to bump libxcb, libX11 etc to 1.2, as I use those from x11 overlay and want the 32bit ones to match (major changes between libxcb 1.1.90 and 1.2), as well as libXext and libXrandr.

Now, crossing fingers, and go!

Comments/Issues:

mesa failed here right away, as it doesn't find the needed 32bit xlibs. I uninstalled the old emul xlibs before testing this of course.

same for pretty much every other x-modular package in this overlay.

E.g. libXmu, when compiling the 32bit part

Code:

/usr/lib64/libXt.so: could not read symbols: File in wrong format
collect2: ld returned 1 exit status

because it just depends in libXt which I do have installed, but still without lib32 useflag.

Whenever USE="lib32" is requested for a package, it's library dependencies need USE="lib32" enabled too. I smell a big EAPI2 and [lib32?] mess is needed here.

Even worse: mesa needs expat, so for -lib32 depending on expat is OK. Now with lib32 enabled, we have to depend on expat[lib32?] or older/current emul-linux-x86-baselibs.

Code:

multilib? ( lib32? || ( dev-libs/expat[lib32?] app-emulation/emul-linux-x86-baselibs ) )
!lib32? ( dev-libs/expat )

Ugh.

Example patch to the mesa ebuild (use EAPI 2 and usedeps, still ignoring the expat issue):

maybe you want to join #gentoo-multilib-overlay on irc.freenode.net

last post in march, how is this project progressing?
is it usable for stable users?

thanks in advance

The eclass approach in the overlay is working well.
But this approach will never go into the portage tree.

Furthermore i do not know if it is possible to simply switch back.

You can use it with a stable system, but you should be aware that this overlay is experimental and it could break your system.

In a second branch we test a approch with a modified portage.
But this one is even more experimental ;-)

join #gentoo-multilib-overlay on irc.freenode.net to get further information

Hi,

i have the following problem using the overlay with paludis:

Python Modules don't compile with the lib32 use-flag:

tbe · n00b Joined: 22 Sep 2009 Posts: 5

Problem solved: Wrong char in bashrc: looks like a ", but was no "

Another Problem:

sys-libs/pam PROVIDE='virtual/pam[?lib32]'

Because of this, pam will reinstalled every time, a package has virtual/pam[lib32] as dep.

Reason (from freenode #paludis): <ciaranm> PROVIDE can only contain simple cat/pkg names

:!:

Some ebuilds in this overlay use PROVIDE with a useflag.

This is wrong! It may break usage of your package manager!

dev-python/numpy fails for me with an access violation (compiling with -lib32). Anyone else experiencing this problem?

Lately, over 50% of packages I try to compile from this overlay are failing. For example, just now media-libs/schroedinger:

@Bogo: the error with media-libs/schroedinger-1.0.7 is a bug in the portage tree not in the overlay
And as drescherjm suggested --keep-going is a nice feature of portage :wink:

Please report your build errors. Else we can not get rid of them.

The best place to report errors and get quick help is the irc chanel: #gentoo-multilib-overlay

Bad example then, but I've had lots of packages fail that are trying to compile from the multilib overlay.

I don't use lib32 as a global flag.

I've noticed that even if I do not use lib32 for a certain package, if that package exists in multilib, it will use that one over the main tree. When those packages fail, I've just rm -rf'd that entry in multilib and the compile will go fine. I specifically remember gegl a few weeks ago, but that has since been fixed.

I'll give --keep-going a shot.

what i read online is that -march needs to be specified for atomic operations to work.
note: turned out i forgot to set my -march flag in my CFLAGS. so much for installing 5 gentoo installations at the same time

with the multilib overlay, I got poor 3D performance for 32bit apps. Counter-Strike and Warcraft III are unplayable, while they used to work before. A 32bit compiled glxgears only has ~100 fps while a 64bit glxgears has more than 300 fps. I have ebuilds for the following multilib packages created myself, because they are not in the multilib overlay yet:
