[gentoo-embedded] GNAP extensions

[gentoo-embedded] GNAP extensions

[Petr Podrabsky]

Hello guys,

I have some questions about GNAP. I have GNAP, catalyst 2.0 versions,
squashfs-tools 3.0, gcc 4.1.1. A default portage snapshot from gnap
package is very small (1,7MB). I can see there are missing some
packages that I need (hostap-driver, and so on…). Ok. In this case I
have to define extensions in myspecs01 dir:

--extensions-conf:
# List of extensions to build
extensions: less hostap-driver hostap-utils quagga

# hostap-driver extension
hostap-driver/packlist: hostap-driver
#hostap-driver/cleanup: /usr/share

# hostp-utils extension
hostap-utils/packlist: hostap-utils
#hostap-utils/cleanup: /usr/share

# less extension
less/packlist: less
less/cleanup: /usr/share

# quagga extension
quagga/packlist: quagga
quagga/cleanup: /usr/share /etc/quagga/samples /usr/include /usr/lib/perl5
--end of file extensions.conf

Then I tried to do extensions like this:
#gnap_make -t extensions -e less -e hostap-driver -e hostap-utils -e
quagga -p portage-20061006.tar.bz2 -o router05 -e myspecs01 -v
20061006C

Gnap_make ends with error:
.....
app-misc/pax-utils
    selected: 0.1.10

How I can solve this portage problem?
Is there any problem I use for GNAP nearly latest portage snapshot
(portage-20061006.tar.bz2 = ~37MB) ?
Should I use some "better" and smaller portage for GNAP?
Where should I find „better" portage snapshot (not big like 37MB)
where hostap-driver, hostap-utils,quagga are included?

Can I do gnap_make –t all with latest portage like this:
gnap_make –t all –p portage-20061017.tar.bz2

Thanks for any info.

Petr

Hi,
my way to do extensions is constructing custom portage by inserting extra 
ebuilds to the standard GNAP portage. All you need is to compress your 
Portage.

Remember that your ebuild may have dependiences so you may have include them 
as well.

As general Portage rules apply, the error is clear. You can use for instance:

ebuild /path/to/quagga digest 

to recreate quagga manifests. Of course you need to do it inside Portage 
tree :-)

Hi Petr,

When using portage overlays the original packages are not removed, so if the 
package is both in the overlay and in the snapshot your resulting package 
directory will contain both the contents from the snapshot and the content 
from the overlay.

If all the files from the snapshot are not in the overlay the generated 
Manifest file will be invalid as some files from the snapshot will remain.

To workaround this you have to copy the contents of the portage snapshot to 
your overlay and do an ebuild packagename digest.

That wasn't too clear but I hope it helps otherwise just ask again.

You should be able to do that. This also solves the overlay problems above.

Ok. My next steps were like this:
1) I added to original gnap-portagesnapshot my wireless apps
(hostap-driver, hostap-utils, wireless-tools, quagga)
2) I had to add metadata for these apps (I am not familiar with portage)  :-)
3) Gnap_make ended with error libpcap was missing.
4) I added libpcap do portage and to matedata
5) Gnap_make went further. But next error appeared:

I have kernel.conf with my actual kernel config. How can I go on?

You can add the following line between the two other boot/kernel lines:

boot/kernel/gentoo/packages: net-wireless/hostap-driver

Yes, It helped a lot. Gnap_make ended before end. 38 packages from 39
were done. I am on way to clean some manifest to get rid of not used
ebuilds. Thanks.

I had to change kernel to 2.6.16-hardened-r11 (default kernel has
problem with squashfs-tools). I copied from latest portage hardened
kernel to portage/sys-kernel/hardened/  and added
linux-2.6.16-hardened-r11 to metadata as well.  Now I have in my
portagesnapshot kernel 2.6.16-hardened-r11. Kernel 2.6.16-hardened-r11
is linked to /usr/src/linux. livecd-stage1 ends with error:

.....

I have no idea where I shloud correct it.

Sounds like the previous problem. Did you readd hostap-driver to 
packages.conf?

It should not be listed in packages.conf but only in livecd.conf like I 
described in the last message.

Did you try to clean out the temp files in /var/tmp/catalyst and building all 
stages?
