ruby-dev

　やまねです。
　遅まきながら（1週間遅れですが）進捗があったのでご報告させて頂きます。
　hppa での Linux カーネルの NPTL サポートの問題に当たったようです。

　お騒がせしました。


　今回の build 問題は解決の見込みですが、引き続き ruby development での
　hppa サポートについてご検討頂ければ幸いです。

Following Michael's steps, I successfully built ruby1.9 on mkhppa3, one
of Thibaut Varene's boxes, using the following kernel:
Linux mkhppa3 2.6.22.19 #1 SMP Tue Oct 14 14:22:05 CEST 2008 parisc64
GNU/Linux

Before that, I tried to build using lenny's 2.6.26. I ran into several
WARN_ON()s and hard locks, and never managed to build ruby1.9 on hppa
using lenny's kernel. This kernel is clearly not ready for a release,
but it's not my call to make...

After the build, ruby's test suite mostly passed (some thread tests just
blocked, so there's still a problem with threading on hppa). So I had to
disable it in debian/rules. I think that the status is "good enough" for
lenny/hppa. And this should allow to build the other missing packages
too.

Dato, is it fine if I upload those binaries to unstable? How should I
proceed to make them migrate to testing? I think they will magically
appear in testing since the source is already in testing, but I'm not
sure now.

Thanks a lot to Michael for hinting about 2.6.22.19 :-)
