Public bug reported:
blcr does not build against the linux-rt kernel (which is at 2.6.31-10
as of up-to-date lucid installed from alpha 3), complaining that symbol
__put_task_struct has not been defined.
If I am not mistaken, this causes dkms to refuse to automatically build
other modules - please correct me if I'm wrong. I've had to invoke dkms
manually to compile the nvidia binary driver support module, and I
assume that the cause of this problem was the failure to compile blcr in
the first place.
I suppose this may be hard to fix if blcr relies on features specific to
2.6.32, given that the only alternative to make compilation work would
be to forward-port the rt patch to 2.6.32. In the past this has been
problematic -- Intrepid and Jaunty had broken linux-rt packages which
wouldn't work on more than one CPU core, besides other issues.
Would it be possible to blacklist blcr from being compiled against the
-rt kernel? Does anything in the standard desktop install of lucid
depend on having a working blcr?
