Hi, I want to know that how can i configure nptl on my linux 2.6.10 kernel.I am confused little bit because when I give the command:->getconf GNU_LIBPTHREAD_VERSION it is returning the value nptl-0.61 but when i am giving the command:-> /lib/libc.so.6 where it is giving following output:->linuxthreads-0.10 by Xavier Leroy instead of Native POSIX Threads Library by Ulrich Drepper et al I am using the gcc version 3.3.3 and Thread Model:-POSIX But when I am giving:->/lib/tls/libc.so.6 it is giving:->Native POSIX Threads Library by Ulrich Drepper et al So tell me whether it is working or not.
