Hi Parav.. > Can you tell me how can I enable this support or how > can I use the NPTL library in my linux kernel 2.6.10? It should be automatically picked by your runtime linker, unless: 1. You set the environment variable to be something like: LD_ASSUME_KERNEL=2.4.9 It will force the linker to use the old linuxthreads OR 2. You explicitly rename or delete (watch out, don't do this!) the directory which contains NPTL enabled dynamic shared library. In Redhat 9, this directory is /lib/tls > Any flags to put in Makefile or something else? No need to put any flags... Anyway, about the extra thread, I am 99.99% sure that is the manager thread. IMHO, it would be a good idea to use strace/ltrace to find out what really happens.. Pay attention to syscall like clone(), fork(), vfork... regards, Mulyadi. -- Kernelnewbies: Help each other learn about the Linux kernel.
