cross-building dependencies and emdebuild
I do a lot of cross-building of plain debian packages, and the
emdebian tools provide almost everything needed to make that painless.
But I found a couple of problems today.
1) Minor one first:
if you do
emdebuild -a arm build-dep
(instead of)
emdebuild -a arm --build-dep
then it carefully emdebianises your sources (changelog and rules).
This is quite annoying, and could probably be considered a bug.
It would be better if it complained of invalid syntax (I don't think
the first line is valid, is it?). That's an easy fix and I really
ought to offer a patch...but my perl-foo isn't quite up to it. It
looks like the code only checks for options it doesn't understand, but
doesn't check if there is a left-over non-option paramter at the end.
2) More significant issue.
If I have a sources.list like this (i.e. stable stuff only):
deb http://ftp.uk.debian.org/debian lenny main
deb-src http://ftp.uk.debian.org/debian/ lenny main
deb http://security.debian.org/ lenny/updates main
deb-src http://security.debian.org/ lenny/updates main
and I have a package with these deps (in xcontrol file):
Build-Depends: libglib2.0-dev, libpango1.0-dev, libx11-dev,
libgtk2.0-dev, libatk1.0-dev, libaspell-dev, libun
gif4-dev, uuid-dev, libxml2-dev, gsmd-dev, lw-dev
Build-Depends-Tools: debhelper (>= 5), cmake (>= 2.4)
then I do
emdebuild -a arm -v --build-dep
it correctly works out that it needs to install libdirectfb-dev
libpango1.0-dev libgtk2.0-dev libcairo2-dev
but then fails to find any of them. (full log below) I think because it is defaulting to looking in
unstable and there seems to be no way to tell it not to, depsite there
being no mention of unstable in my apt sources lists.
if I do
apt-cross -a arm -i libpango1.0-dev
if fails to find it:
....
Installing: libdirectfb-dev libpango1.0-dev libcairo2-dev
E: Broken packages
apt methods failed for libdirectfb-dev_1.0.1-11_arm.deb, falling back to direct cache path.
Trying: path=http://www.emdebian.org/debianpool/main/d/directfb/libdirectfb-dev_1.0.1-11_arm.deb
Filename: libdirectfb-dev_1.0.1-11_arm.deb
....
but if I do
apt-cross -a arm -S lenny -i libpango1.0-dev
if works fine.
So I think all that is needed is a way to tell emdebuild which suite(s)
to use or better, for it or apt-cross to use the ones in the apt lists.
Attached is the patch that Neil did a which time ago for emdebuild to
have a -S Suite override. I guess this is already in newer versions of
emdebian-tools? In which case this problem only afflicts builds in the
stable environment using the stable tools.
It is pretty-much fatal though for any non-trivial cross-building. IN
which case I suppose the advice is to use emdebian-tools
<fx:checks>. Yes. upgrading to apt-cross 0.12.6 fixes the above
problem so that
apt-cross -a arm -i libpango1.0-dev
now works.
hmm, but apt-cross -a arm -i libgtk2.0-dev
doesn't.
and emdebuild -a arm -v --build-dep
still fails to find any packages, but
emdebuild -a arm -S lenny -v --build-dep
does now work - hooray!
why does emdebuild need to be told which repo to use? Is there a
reason why can't it work it out from the apt sources list?
