No executable will use linuxthreads without being run with special environment variables. If there are many binaries and scripts and it's hard to tell what might be going on, you can take a running application and look at its /proc/PID/maps to see which libraries are being mapped. On FC4 the linuxthreads libraries are in /lib/obsolete/linuxthreads/, so that's pretty easy to spot. On earlier versions it's in different places. But if you are concerned about FC5 compatibility, the first thing to do anyway is make sure you are happy with upgrading to FC4. -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/fedora-devel-list
