It was caused by tls_fix patch (taken from Fedora Core) not updated at proper time - i.e. one linuxthreads/alpha change in patch didn't follow nptl/alpha change done in sources before 2.3.4 release. I hope I fixed it properly. (This patch is needed to have both LinuxThreads and NPTL libraries installed, selectable at runtime. Unpatched glibc sources support only one threads library at a time, so one would need to choose: NPTL or ability to boot system on 2.4.x kernel/run some app incompatible with TLS/NPTL.) -- Jakub Bogusz http://cyber.cs.net.pl/~qboosh/ _______________________________________________ pld-devel-en mailing list [email protected] http://lists.pld-linux.org/mailman/listinfo/pld-devel-en
