Public bug reported:
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 named like linux-image-2.6.32-25-generic I should get
linux-image-2.6.32-25-47349f-generic.
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
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.
To reproduce:
* 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
commit 47309c6a6af8cce3586c735788fc978bbcd7249f
...
$ echo $SHELL
/bin/bash
$ 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
