How to enable NPTL? (Wombat) 0.7

I have installed and updated (pacman -Syu) Arch 0.7 and when I do
/lib/libc.so.6
I get

Am I not supposed to see NPTL in here?

Eh? I think you'd have to recompile it with NPTL support instead of linuxthreads...

(IIRC, glibc can't be compiled with both.)

Re: How to enable NPTL? (Wombat) 0.7

the nptl ones go in /lib/tls

if you d o /lib/tls/libc.so.6 you should see that this is displayed:

Besides that, running /lib/libc.so.6 doesn't do anything useful. Detecting if you have something by running that lib is stupid. The GNU people introduced the getconf program for that a very long while ago:

[root@server ~]# getconf GNU_LIBPTHREAD_VERSION
NPTL 2.3.3

[root@server ~]# LD_ASSUME_KERNEL=2.4.20 getconf GNU_LIBPTHREAD_VERSION
linuxthreads-0.10
