I added several patches today to the new experimental building system, and added a script at linuxtv.org to auto-generate a tarball with the latest drivers. Basically, with the patches I made, it is compiling fine with the following kernel releases (vanilla upstream kernels): linux-2.6.32.24 linux-2.6.33.7 linux-2.6.34.7 linux-2.6.35.7 linux-2.6.36 (e. g. the latest stable releases from 2.6.32 to 2.6.36). The 2.6.32 backport also compiled fine with the experimental RHEL6 kernel I have on my machine. WARNING: I just test compilation. There are some random warnings generated with some of those kernels that may or may not indicate a problem. If you want to test the new building system, all you need to do is: $ git clone git://linuxtv.org/mchehab/new_build.git $ cd new_build $ ./build.sh This will download the newest tarball from linuxtv.org, apply the backport patches and build it. After that, you may install the new drivers with: $ make install The building system is the same as we had on the mercurial tree, but I didn't test the other targets (well, except for make release DIR=<dir> - it is also working fine). Yet, I think that the other make targets should be working properly. Patches (and a maintainer) are welcome. Have fun!
