Questions from a greenhorn about build problems

[Rainer Koenig <Rainer.Koenig@ts.fujitsu.com>]

Hi all,

I'm using yoctoproject since one week now and got the latest
yocto-1.1/edison-6.0 git tree. I have been able to build core-image-sato
for the Beagleboard xM rev. A and the image works fine.

Now my next goal is to build an image for the TI 8148 EVM board. Since
Yocto is based on OE-core I thought it was a good idea to get the
meta-texasinstruments layer that is listed in the OE wiki:
http://www.openembedded.org/wiki/LayerIndex

So I cloned my git tree for meta-texasinstruments from
git://git.angstrom-distribution.org/meta-texasinstruments

and looked a bit around in that. conf/machine shows a conf for
c6a814x-evm so I replaced the machine "beagleboard" with "c6a814x-evm"
in my local conf.

I started `bitbake -k core-image-sato` and after builing around 4100 of
the 4221 recipes I got an error on a kernel tree from the arago-project
and from the u-boot compilation. I guess the second error occurs because
of the first error, so I had a better look at the first error.

The buildstats for this packet show, that fetch failed. I tried to fetch
the SRC_URL by hand and it worked without any problem. Note: I'm behind
a firewall, so to clone git://... I need to go over a SOCKS proxy.
Therefore I created an /etc/gitconfig that works fine and the downloads
show, that lots of git-repos from the yocto recipes worked without any
probem, but now those from the meta-texasinstruments layer seem not to
work. I tried a bit around with bitbake -b -D and saw long commandlines
with lots of export before.

It exports a GIT_CONFIG which points to
poky/tmp/sysroots/x86_64linux/usr/etc/gitconfig.

First I replaced this gitconfig with my own gitconfig from /etc, but
that didn't work. Looking at the file structure there it seems that
../sysroots/x86_64linux/ is chroot'ed somehow so I put gitconfig under
that chroot's /etc and now it seems that fetch is working.

So stupid question: Is there a documentation that explains how that
build process is working on the machine/script level and why are the
recipes from yocto behaving different than to the ones that I imported
with the meta-texasinstruments layer?

Best regards
Rainer
