Hello Jonathan,

thank you for your fast reply! The reason why I didn't get build-errors is because I passed '-d' (don't check build-dependencies) to debuild. But exactly that might be the problem.

I want to repackage rkhunter to include a patch for our local repository. The build-machine is Ubuntu Trusty and the Target is Ubuntu Precise (the issue has been fixed in Trusty). So I tried sbuild and pbuilder but I don't seem to get the setup right.

I will try to get more into packaging and will report when succeeding. In short this error could relate to config-package-dev (with pbuilder-dist-simple):
dh: unable to load addon config-package: Can't locate Debian/Debhelper/Sequence/config_package.pm in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.14.2 /usr/local/share/perl/5.14.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.14 /usr/share/perl/5.14 /usr/local/lib/site_perl .) at (eval 3) line 2.

My pbuilder-environment doesn't seem to work for the intended purpose, while building the source package as is works fine.

Cheers
Sascha

Hi Sascha,

Per dh_configpackage(1), the transform script provides the un-transformed version of the file on stdin, and expects the transformed file on stdout, so that invocation of patch won't actually do anything.  You probably want something like:

patch -N -f -r - -o - -i rkhunter.patch

That will cause patch to send the patched file to stdout, and read the .patch file directly, without using I/O redirection.  stdin would then be ignored.  However, that's probably also a bad idea, since patch will still look for the source file (to be patched) on the filesystem.  There is, as far as I can tell, no good way to get patch to use stdin as the original (to-be-patched) file.

That having been said, I'm not sure why you saw no errors in the build process - in some cursory testing, patch errored out, and thus dh_configpackage failed, and the build stopped.

If you want to use patch, the easiest way is probably with a separate transformation script (as described in the manpage), which can read the original file on stdin, write it somewhere temporary, apply the patch and generate the result on stdout.

Hello,

How would I apply a patchfile to a file in a .transform notation? What I tried:
seait-rkhunter.transform:
/usr/bin/rkhunter.seait  patch -N -f -r - < rkhunter.patch

On Ubuntu Trusty i got the sources:
apt-get source rkhunter/precise

Added config-package and rkhunter to Build-Depends in control Put
'--with=config-package' in the rules

Altered Version:
dch -l+seait

Build the package with: debuild -us -uc -i -d

The package seems to build fine. No errors are reported in the buildlog. But /usr/bin/rkhunter is not patched neither is it linked to rkhunter.seait nor is there a rkhunter.orig.

Cheers
sascha
