Description Alan Hourihane 2005-04-14 21:12:49 UTC 
I'm getting a build failure with glibc 2.3.5, below is the error when building nptl.

With gcc-3.4.4 and glibc-2.3.6 this error still persists

Comment 3 Denis Vlasenko 2006-06-19 11:33:39 UTC 
The problem seems to be here:

nptl/sysdeps/unix/sysv/linux/i386/lowlevellock.h (fixed):

//vda: seems like bug?
//extern int __lll_lock_wait (int val, int *__futex)
//     __attribute ((regparm (2))) attribute_hidden;
extern int __lll_lock_wait (int *__futex)               //
     /* __attribute ((regparm (1))) */ attribute_hidden;      //

All other arches have __lll_lock_wait() with ONE argument (int *__futex),
and nptl/sysdeps/unix/sysv/linux/lowlevellock.c does expect that.

Why this bug is marked as a dup of a bug 333 "This is a placeholder bug; other
bugs are marked as duplicates of this bug when they are improper reports about
problems compiling glibc" - is beyond me.
Comment 4 Jakub Jelinek 2006-06-19 11:39:07 UTC 
Because it is a user error - you are trying to build NPTL on an architecture that
is not supported by NPTL.  On i?86 NPTL only supports i486, i586, i686 or newer,
not i386 (which doesn't have the minimal set of atomic instructions that is
required for NPTL.

Comment 5 Denis Vlasenko 2006-06-19 13:02:00 UTC 
Awwwwwww how stupid! THANKS! Rebuilding for i486...
