 Posted: Wed Aug 27, 2008 5:19 am Post subject: embedded gentoo uclibc env-update [SOLVED... sort of] |
 |
|
**UPDATE**
Problem was averted by using a stage 1 install (stage1-x86-uclibc-2008.0.tar.bz2)
**END UPDATE**
Hey everyone,
I am not sure this is the thread for this post but I will shoot for now. I am installing gentoo on a tmz104 pc/104 board (x86 architecture), I know gentoo works as I was able to run a live disk on it... (ironically of all the distros I tried, debian freebsd, netbsd etc... gentoo was the only one that worked.) The problem ariises not with the board itself but instead my actual computer. I try to build the gentoo embedded environment on my computer in a folder, so i download the latest stage3 tarball which is stage3-x86-uclibc-2008 and do the following commands:
| Code: |
#tar -xvjpf stage1-x86-uclibc-2008.0.tar.bz2 -C /opt/gentoo_uclibc/
#mkdir -p /opt/gentoo_uclibc/usr/portage
#mount -o bind /proc/ /opt/gentoo_uclibc/proc
#mount -o bind /usr/portage /opt/gentoo_uclibc/usr/portage
#chroot /opt/gentoo_uclibc/ /bin/bash
I have no name!@localhost / $
|
At this point it seems confusing as I don't appear to be root after chrooting and it says "I have no name!", but the annoying part comes up with this:
| Code: |
I have no name!@localhost / $ 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 98, in ?
from portage_data import ostype, lchown, userland, secpass, uid, wheelgid, \
File "/usr/lib/portage/pym/portage_data.py", line 83, in ?
if secpass < 1 and portage_gid in os.getgroups():
OSError: [Errno 38] Function not implemented
|
I cannot seem to wrap my head around this one as I get stuck with env-update, emerge etc... BUT if I do a normal stage 3 x86 for a regular gentoo install instead of a uclibc stage on the same computer, it works fine... So my question is why env-update failing?
For reference I used these sources for information:
http://www.bulah.com/embedded-guide.html
http://gentoo-wiki.com/TinyGentoo
Any help would be greatly appreciated!

Within the uclibc chroot, what's your UID (echo $UID or just run `whoami`)?
If it's something like "4294967295", then you've probably run into the same issue I and at least one other gentoo user encountered before, see here.
If this is the case, then it's actually a kernel configuration issue, you need to enable CONFIG_UID16, which is "Enable 16-bit UID system calls" under "General setup -> Configure standard kernel features (for small systems)" in menuconfig.
That's what we get for over "optimizing" our kernels. 
fwiw, I believe more recent versions of uclibc no longer require this, however it'll probably be a while before we see it in portage.
anyways, HTH

Well I am getting the 4294967295 value when I type echo $UID.
Now is that "Enable 16-bit UID system calls" needs to be enabled on the host kernel?
Remember I cannot even run env-update or emerge... |

Yes, in the host kernel.

Well i compiled in the "Enable 16-bit UID system calls" into the kernel and that seemed to fix things! Thanks for the help! I really appreciate it!
Although I was wondering if any of the documentation should be updated to include compiling "Enable 16-bit UID system calls" into the host kernel? |

Huh well i ran into a problem, seems that when I try and run:
After a couple of packages I run into a problem with sys-devel/patch-2.5.9r1, here is the build log:
| Code: |
>>> Unpacking source...
>>> Unpacking patch-2.5.9.tar.gz to /var/tmp/portage/sys-devel/patch-2.5.9-r1/work
Child died with signal 11
Error exit delayed from previous errors

* Call stack:

* environment, line 2376: Called unpack 'src_unpack'
* ebuild.sh, line 348: Called die
* The specific snippet of code:
* tar zoxf "${srcdir}${x}" ${tar_opts} || die "$myfail"
* The die message:
* failure unpacking patch-2.5.9.tar.gz
*
* If you need support, post the topmost build error, and the call stack if relevant.

Any suggestions? |

It seems the ebuilds are not unpacking properly:
| Code: | | tar -zoxf package.tar.gz |
I used a standard portage snapshot, is there a special one for uclibc stages? |

| Well fixed the problem... sort of using a stage 1 uclibc install stage, perhaps the stage 3 has problems? Looks like I have an embedded system of about 4.6MB. Again thanks for the help! |
