[Buildroot] nptl depends on uclibc

[Buildroot] nptl depends on uclibc

[Daniele Salvatore Albano - Lavoro]

  Hi,

i'm trying to setup a development system using ct-ng with eglibc but, 
while configuring stuff, i've seen that only linuxthreads and 
linuxthreads old are usable and not nptl.

Looking at configuration file i've seen that there is a depends on 
uclibc snapshot.

Is this correct? NPTL should be default, or, however, should be 
selectable when using eglibc and when using glibc.

Thank you,

Best Regards,
Daniele

default not yet. When uclibc releases with nptl then it can.

thats a fair point.

This is a known issue. There is currently no way to tell buildroot that an
external toolchain is using NPTL.

There has been a discussion about in in the recent past, but I can't recall
what was the outcome...

Basically, buildroot should not have to know what threading implementation
is being used, as it has no partical user-visible impact. There are currently
only two packages that have dependency on NPTL: openvpn and ltp. For others,
you should be able to safely use an NPTL toolchain without telling buildroot.

I'll look into that during the WE, hopefully.

Yann E. MORIN.
