Compiling U-Boot for beaglebone on Gentoo (arm7a) fails...

[mcc2]

Hi,

I am trying U-Boot from git by myself and followed this
http://dev.gentoo.org/~armin76/arm/beaglebone/install.xml
instructions.

The compilation fails with:

...seems to be the final step.

If this is only a temporary bug cause the git conatins some buggy
code...no problem.
If I did something wrong or be able to fix it I would like to know,
what goes wrong...?!?
How can I get/create this ".rel.plt" file ?

Thank you very much in advance for any help !

What the hash of your pull? If it's not the same as below, then try the version below which I recently successfully cross compiled:

Hi,

mine is:

from eix point of view it is the same version...

Seems I am out of luck...what can I do next?

Just so where closer to apples to apples, would you post the results of:

Hi jlpoole,

this is the output:

Try reverting to the version I used and then attempt to compile; the version you have may very well be broken especially since the author noted it was "testing". You'll have to read up on the basics of GIT.

Hi jlpoole,

git log -1 now produces

commit 5c0406ddff69cd0b3d5271ba5cd98b44eac39c6e

AM33XX: boot commands for booting from emmc on mmc1

Signed-off-by: Joel A Fernandes <joelagnel@ti.com>

here, but unfortunately the error remains the same...

Any idea, what to try else...?

(with the toolchain I compiled a complete Angstrom image
(rootfs,xfree,windowmanager) so dont think, it is buggy...)


Best regards,

My ineptitude with git did not allow me to modify my existing tree, so I started anew and downloaded a fresh image and configured and cross compiled it. It did not appear that the compile successfully ended; however, the u-boot was generated so I'm not arguing with success.

The session (less the entire make.log) can be viewed for the next month at: http://pastebin.com/9P3m6S19

The salient points from my session are:

[jlpoole]

The error generated from my cross compile against the Yanok commit of Thu Aug 9 02:10:14 2012 differ than the errors at the start of this post.

Question: was u-boot built? My errors seem to appear after-the-build. I'm assuming yours were before u-boot was built.

At any rate, if you do not have u-boot, then kindly replicate what I just did using the Yanok version and paste-bin, then let's ask Mark Frysinger [Vapier] what he thinks we can do to ferret out the discrepancy. The cross compiler should give us the same error messages when run against the same source; that it does not merits investigation and possibly a bug.

Hi all,

I've updated my guide for installing the beaglebone, with all the issues fixed like the u-boot build failures that like you, i also hit...

Hope it helps.
