Hi,

here is my experience with the Ubuntu 7.04 conf file on a local build server:

I didn't have to add anything to the build file, building of my custom package succeeds, but there are a few things that I think are worth mentioning:

- Dependency problems: There are the same dependency problems in my log file, like on the public build server, (for example project net-snmp), they do not seem to be a problem, and a few lines further down the offending package gets installed. Interesting.

If you know, how the package is called under Ubuntu, you want to require with "rpm-devel", we can add mappings for this. You can also try on your own, in you build service instance, by editing the project config ( osc meta prjconf -e <project> ). A Substitute: Requiered_Package_Name Ubuntu_Package_Name can solve these kind of issues. We can also do so in our instance, if someone can provide a list.

- libstdc++6-4.1-dev: There is an expansion error if I do not fix the libstdc++-dev package in the .dsc file to libstdc++6-4.1-dev.

expansion errors: have choice for libstdc++-dev needed by libboost-dev: libstdc++6-4.1-dev libstdc++5-3.3-dev have choice for libstdc++-dev needed by libsigc++-2.0-dev: libstdc++6-4.1-dev libstdc++5-3.3-dev

This is also a bit strange since I would assume that gcc 4.1 is prefered and the -dev package dependency should be resolved automatically.

No, there is no version handling at this point, so one needs define it. Also gcc41 seems not to require a specific version, this could be considered as a packaging bug. But again, a line in prjconf can solve this :), for example Prefer: libstdc++6-4.1-dev

- missing obs dependency 'deb.rpm'. Installing the build server does not automatically install the debian tools package. I think it should do. Without deb.rpm there is an error in debian builds: "dpkg-scanpackage not found".

Hm, since the obs can be used also without, a Requires is maybe too strong. But I added a Recommends for this.

Apart form these items my Ubuntu builds succeed now; the build server is really a great tool!

cool :)

cheers Chris

Example of weird dependency problem from a log file (marked up with ***):

... preinstalling ***belocs-locales-bin***... ... dpkg: locales: dependency problems, but configuring anyway as you request: locales depends on ***belocs-locales-bin*** (>= 2.4); however: Package belocs-locales-bin is not installed. installing libc6 installing base-passwd ***installing belocs-locales-bin***

Hm, I guess we do not want to enforce to install "locales", but maybe I am wrong.

Hi,

I copied the conf file from Debian.conf for my local Ubuntu builds; the build is starting, but then there are some error messages about missing packages and dependency problems.

I updated my Ubuntu conf files with the list of preinstalled packages from a build log in the public build server. It improved a bit...

Is there a way to obtain the Ubuntu 7.04/7.10 conf files that are currently used on the public build servers?

osc meta prjconf <projectname>

prompts it to stdout.

I am happy to hear about any corrections/additions to the files :)

bye adrian
