Hello, I've been trying to solve this problem for two days now. I've been following the guide on the gentoo wiki ( http://gentoo-wiki.com/TinyGentoo )but as soon as I try to run env-update I get the following error:

Gentoo gentoo_uclibc # chroot /mnt/gentoo_uclibc/ /bin/bash
I have no name!@Gentoo / $ env-update
Traceback (most recent call last):
File "/usr/sbin/env-update", line 27, in ?
import portage
File "/usr/lib/portage/pym/portage.py", line 75, in ?
from portage_data import ostype, lchown, userland, secpass, uid, wheelgid, \
File "/usr/lib/portage/pym/portage_data.py", line 85, in ?
if secpass < 1 and portage_gid in os.getgroups():
OSError: [Errno 38] Function not implemented

The same goes for when I try to run emerge:

I have no name!@Gentoo / $ emerge
Traceback (most recent call last):
File "/usr/bin/emerge", line 28, in ?
import portage
File "/usr/lib/portage/pym/portage.py", line 75, in ?
from portage_data import ostype, lchown, userland, secpass, uid, wheelgid, \
File "/usr/lib/portage/pym/portage_data.py", line 85, in ?
if secpass < 1 and portage_gid in os.getgroups():
OSError: [Errno 38] Function not implemented

I've been googling and searching for answers on the forums, but nothing could help me out.
Thanks in advance

My guess is that somehow python got built not to handle a specific feature that's in full libc and not available in uclibc. (and for this reason I'll never build a "full" x86 system (one that is able to run any app regardless of how much diskspace is available) with uclibc).

You could go and hack portage/python script to remove that os.getgroups call to get around this problem temporarily?

it looks like uclibc should support getgroups, may be able to get it to build uclibc with this function...

Hacking the script worked, thanks.
Can't believe it actually worked O.o so it'll probably give me trouble later on ^^

It probably won't, for this specific case because it's merely a security check.
But I'm assuming this machine was only for one user anyway so probably safe keep the hack...

Just go to /usr/lib/portage/pym/portage_data.py and remove that line (around line 83 or wherever it's bombing out on you) that say:

Code:
        if secpass < 1 and portage_gid in os.getgroups():


This will force security to pass regardless of your group ID. Security hole, yes. But it gets by the problem...
