KernelCompile - incorrect instructions for usage of AUTOBUILD
Status in “ubuntu-docs” package in Ubuntu:
Binary package hint: ubuntu-docs
This is a report about help.ubuntu.com/community/Kernel/Compile.
I didn't just dive in and change it because I wanted to check I wasn't making things worse. If you think I'm right let me know & I'll go fix the page.
I think the information on this page regarding building ubuntu kernels
from the ubuntu git repository has some errors. I may be doing some
thing wrong but here is what I observe.
I want to build a checkout somewhere between two tags
(eg revision 47309c6a6af8cce3586c735788fc978bbcd7249f.)
Setting the AUTOBUILD variable is supposed to make the build process
append a string to the ABI number. Instead of packages like linux-
image-2.6.32-25-generic, I should get linux-image-2.6.32-25-47349f-
To make this happen I have to run the build like this:
fakeroot debian/rules clean AUTOBUILD=1
fakeroot debian/rules binary-generic AUTOBUILD=1
HOWEVER, doing it as described in the page
fakeroot debian/rules clean
AUTOBUILD=1 fakeroot debian/rules binary-generic
does not work, for two reasons.
1. if AUTOBUILD is not set when you run debian/rules clean, the ABI number is not given the extra suffix when debian/control is created. So the kernel build goes ahead but the packaging step fails with an error like this:
dpkg-gencontrol: error: package linux-image-2.6.32-24-47349f-generic not in control info
2. I find that placing the AUTOBUILD=1 before the 'fakeroot' does not work, neither this way:
AUTOBUILD=1 fakeroot debian/rules ...
nor this way
export AUTOBUILD=1 ; fakeroot debian/rules ...
Doing it with AUTOBUILD=1 given after the makefile name (debian/rules) does work.
* check out the kernel git as per https://wiki.ubuntu.com/KernelTeam/KernelGitGuide
* run the 'printenv' target of debian/rules with AUTOBUILD set or not set.
Here are my results:
$ git remote -v
origin git://kernel.ubuntu.com/ubuntu/ubuntu-lucid.git (fetch)
origin git://kernel.ubuntu.com/ubuntu/ubuntu-lucid.git (push)
$ git show
$ echo $SHELL
$ fakeroot debian/rules printenv|grep abinum
abinum = 25
$ AUTOBUILD=1 fakeroot debian/rules printenv|grep abinum
abinum = 25
$ fakeroot debian/rules printenv AUTOBUILD=1 |grep abinum
abinum = 25-47349f
$ cat /etc/lsb-release
