This is definitely incorrect and breaks systems with 'modern' multilib.

And systems with SYMLINK_LIB=no (bug 506276)

It seems like this eselect module assumes there will only ever be two ABIs; mips has three.

This could use a bit of work. I'll see what I can do.

x86 has three too ;)

I'm sorry about sitting with this in my github bug staging overlay for, err years...
Comment 6 Dainius Masiliūnas 2016-02-23 23:27:45 UTC
While that solves the x32 issue, it's... still pretty ugly. For one, calling the other two options "32bit" and "64bit" is wrong to begin with; x32 is technically 32bit too. They should either be called by archs ("x86" and "amd64"), or by ABI_X86 and /usr/lib* names ("32" and "64").

In addition, instead of copying everything, maybe it could generate the list of all ABIs on the fly, to prevent the same issue happening as soon as another ABI is added (or removed)? I think that was the original idea of this bug report to begin with. And just checking whether /usr/lib is a symlink sounds rather fragile to me.

Also, I think this bug report should also block the x32 tracker bug.
Comment 7 Mike Gilbert gentoo-dev 2016-02-26 13:11:08 UTC
I have done some more extensive changes to this, I just forgot about them for a year.

After consulting with the X11 team, we agreed that the 32bit and 64bit options are rather pointless, so I removed them. Instead, all configured libdirs are updated in-sync.

The ebuild will need to be adjusted to replace LIBDIRS=( lib ) with the real list if libdirs configured in the profile at build time.
Comment 8 Dainius Masiliūnas 2016-07-29 15:15:55 UTC
So what's the plan forward now? Nuke eselect-mesa altogether?

This should be implemented in app-admin/eselect and reused by other modules. Currently the list of libdirs is hardcoded [1]:
ES_VALID_MULTILIB_DIRS="lib lib32 lib64 libx32"

Good point. I forgot eselect had a library for this.

This is a very frustrating bug. It took me a couple of days to figure out what the problem with the opengl apps is...

An update broke the opengl apps. Because of this bug, in eselect mesa I see
teres ~ 
# eselect mesa list
i915 (Intel 915, 945)
i965 (Intel GMA 965, G/Q3x, G/Q4x, HD)
r300 (Radeon R300-R500)
r600 (Radeon R600-R700, Evergreen, Northern Islands)
sw (Software renderer)
teres ~ 
# eselect mesa show
teres ~ 

The bug is around for over 4 years. Should it get fixed?

Should be fixed by
