[ODROID-C1] kernel compilation fails

[chjordan]

Hi,

I have an external xfs drive, and the ODROID-C1 kernel does not provide xfs support. So for a long time, I've cloned the PKGBUILDs repo and added in xfs support and compiled without issue. However, recently, this doesn't work anymore - vanilla or with xfs support added.

Running makepkg -si on the most recent commit eventually fails with:
$this->bbcode_second_pass_code('', '

==> ERROR: A failure occurred in build().

')

Running makepkg -ei after this: reveals:

I'm curious why my build fails but the PKGBUILD is provided upstream, which presumably is the same one used to generate the binary in the repos. Also, I assume hard floats are being used everywhere? A grep of "float=hard" shows no instances in the unpacked kernel directory, but there's a few instances of "float=soft". At this point, I'm out of my depth.

Help is much appreciated.

1. a full log would be nice. You can use pastebin.
2. do remove src and pkg directories before trying to build each time
3. What is in /etc/makepkg.conf
copy paste output of "cat /etc/makepkg.conf" use code tags.

You can also submit a Pull Request on our github, but do it right and read https://github.com/archlinuxarm/PKGBUIL ... IBUTING.md first

Thanks for your reply. From a completely clean "git pull" (except for the .tar.gz already downloaded), the full log of "makepkg -si" is: http://pastebin.com/Vib8c7pQ

To better highlight the (probable) problem, the log of "makepkg -ei" right after the above is:

I've tried removing src and pkg between alterations - no difference. Also, all packages are up to date, gcc is from the repos, nothing funky going on.

/etc/makepkg.conf - I believe this is vanilla (at least, I don't remember making alterations). No .pacnew either.

I do have MAKEFLAGS=-j4 defined in my environment, but I think that's not the issue.

Finally, I did attempt a pull request for xfs support. In my incompetence, I chopped up the modified kernel config file, ignoring changes to container support (enabling xfs disables USER_NS). So the pull was rejected. xfs support will need to be added with some kind of patch: https://github.com/archlinuxarm/PKGBUILDs/pull/1124

[moonman]

Ah I see now. Yeah xfs needs to be backported from later kernels to support user_ns, which may not be trivial.

Did you re-use config from your previous builds or did you adjust the latest config available on our github to support xfs. The error is with backports and it seems config was adjusted in https://github.com/archlinuxarm/PKGBUIL ... 42a5996a3b

I'll try to build it with xfs.

[chjordan]

When I want to build with xfs, I just enable the ncurses option in the PKGBUILD, then enable:

CONFIG_XFS_FS=m
CONFIG_XFS_QUOTA=y
CONFIG_XFS_POSIX_ACL=y
CONFIG_XFS_RT=y

However, in my second post of this thread, everything is vanilla. So I'm wondering if it's my system or something else... Waiting for your build results

[moonman]

Tried building right on my system. No go, same error. Tried in clean chroot and it seems to have passed the point of the error. I haven't configured chroot in anyway so it is building on 1 core and without distcc - it will take a while.

But for reference: read this to build in clean chroot: https://wiki.archlinux.org/index.php/De ... ean_Chroot but use "devtools-alarm" instead of just "devtools".

EDIT: It built fine in clean chroot. To save you some time since I already built this package it is available here and headers here:

Don't know why and how it picks up soft float cflags without chroot though. The important thing is that alarm build system always builds in a clean chroot

Only just noticed the edit - thanks!

Hey, sorry to bring up this old thread but I also have an external drive I would like to get to work on my odroid c1. How do i install arch with the files you posted below? Thanks for any help in advance.

[thatonedude]

Hey, thanks for the quick reply but unfortunately that did not work for me I am still getting the error even after a fresh install and only installing the two xz files and a full update/reboot. Is there anything I am missing?

Thanks

edit: I figured out that I shouldn't do a full upgrade after downgrading the headers and got it to work thanks for all the help.
