Nevertheless, all of these +programs could still be built -- and most of them would indeed be useful -- +without actual support of these hardware devices, kdebase for instance. However, +as the libraries are presently not available for Hurd, the programs can't be +easily built in Debian GNU/Hurd due to missing dependencies. + +This could be avoided by providing dummy libraries, which the programs could +link against, but which wouldn't actually do any hardware access: instead, they +would simply return appropriate error codes, reporting that no devices were +found. + +There are two possible approaches for providing such stub libraries: Either +implement replacement libraries providing the same API as the real ones; or +implement dummy backends for the Hurd in the proper libraries. Which approach +to prefer probably depends on the structure of the various libraries. + +The goal of this project is to create working dummy libraries/backends for the +mentioned devices, and get them into Debian GNU/Hurd. It shouldn't require any +special previous knowledge, though some experience with build systems would be +helpful. Finishing this task will probably require learning a bit about the +hardware devices in question, and about Debian packaging. + +Possible mentors: Samuel Thibault (youpi) + +Exercise: Get one of the libraries to compile on Debian GNU/Hurd. It doesn't +need to report reasonable error codes yet -- just make it build at all for now. |
