[Soc-coordination] Report 1 - Clang for build services

[Alexander Pashaliyski]

I contacted the Alioth admin team via the web site, requesting to use their server for my project "Clang for build services". I got approved and I created a git repository where I'm now uploading my work.

I have a fully functional buildd infrastructure installed on my development environment. In order to get it running, I made several patches. I wrote almost complete documentation on setting up buildd and wanna-build. I have some minor things to refine.

I started to modify the source of sbuild and I have some progress. Currently I have hard-coded clang as a compiler and sbuild uses it for building (except the packages that have gcc hard-coded). Everything works fine so far. I add the name of the used compiler to the control file and the name of the deb package. I'm also testing the build process with some packages that I've selected - several written in each of C, C++, Objective-C and Fortran. Next I'm going to write a function that cheks for hard-coded compiler and takes appropriate actions if there's such.

Here's the wanna-build database at the middle of the building process:

wannadb=# select package,distribution,version,state,previous_state,state_change from amd64.packages;
  package    | distribution |         version          |    state    | previous_state |        state_change

These are the files that buildd have created at the same moment:

To get everything working so far I've made changes to wanna-build, sbuild, buildd, reprepro and dpkg.

This is a link to the repository that I use to upload changes to sbuild and buildd:
