Bug 261670 – portage-2.2_rc23: usepkgonly fails with multilib packages

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Francisco J. Vazquez 2009-03-08 11:28:22 UTC]

I don't know if this is a bug or the intended behaviour, but I cannot emerge binary packages that use -m32 (grub, wine) with --usepkgonly. I get this error:

franjva@quad00 ~ $ sudo emerge -1K grub
Calculating dependencies... done!

!!! All ebuilds that could satisfy "sys-boot/grub" have been masked.
!!! One of the following masked packages is required to complete your request:
- sys-boot/grub-0.97-r9 (masked by: CHOST: i686-pc-linux-gnu)

For more information, see the MASKED PACKAGES section in the emerge
man page or refer to the Gentoo Handbook.


Reproducible: Always

Steps to Reproduce:
1. emerge --buildpkg grub
2. emerge -K grub
3.

Actual Results:  
2nd emerge fails with the aforementioned error

Expected Results:  
2nd emerge uses the binary package built in the previous emerge

franjva@quad00 ~ $ emerge --info

Reassigning to portage team, CCing maintainer.

[Comment 2 Zac Medico 2009-03-09 20:02:47 UTC]

It should work if you set this in make.conf:

ACCEPT_CHOSTS="x86_64-pc-linux-gnu i686-pc-linux-gnu"

I suppose we might want to add this setting to the amd64 profiles. However, in a way it defeats the purpose of ACCEPT_CHOSTS because it's conceivable that you wouldn't want to accept CHOST=i686-pc-linux-gnu from some packages...

[Comment 3 Zac Medico 2009-03-09 21:01:13 UTC]

I'm told that the multilib_toolchain_setup function in multilib.eclass is what's responsible for changing the CHOST.

[Comment 4 solar (RETIRED) 2009-03-09 21:27:24 UTC]

This looks like the commit that broke it.
http://sources.gentoo.org/viewcvs.py/gentoo-x86/eclass/multilib.eclass?r1=1.71&r2=1.72

It should restore the environment before the pkgmgr saves the env.

[Comment 5 Zac Medico 2009-03-09 23:33:06 UTC]

In svn r12810 I've added a QA Notice that is triggered if CHOST at install time differs from the initial CHOST setting.

This warning is included in portage-2.2_rc24.

I can make portage store the original CHOST, regardless of what the ebuild has done. Is that how we want to handle this?

[Comment 8 SpanKY 2009-03-12 06:54:25 UTC]

if anything, the package is more truthful about what's going on.  these are packages which are not native to the default CHOST.  they're native to the CHOST that the multilib function changed it to.

until portage gets properly multilib support (which is probably never anyways), then feel free to simply ignore the CHOST after the emerge has started.

note that i have no clue what this bug is about in the first place ... or what this "ACCEPT_CHOST" business is for ...

Ok, we'll just ignore it then. It's fixed in svn r13088 to revert the CHOST to the initial value.

[Comment 10 Zac Medico 2009-03-12 10:07:34 UTC]

This is fixed in 2.2_rc25 which is in package.mask. I'll close this bug when
it's also released in 2.1.6.8.

[Comment 11 Zac Medico 2009-03-13 20:44:19 UTC]

This is released in 2.1.6.8.
