Seems like pthreads in uClibc not fully supported...

pthread_condattr_setclock() seems to be available in the NTPL branch of uClibc. Mike: could you please comment on this? Is this branch going to be used as a basis for the next release of uClibc? Is it possible to get something based on it into Portage?
no, it wont be
No idea about how could this be solved then :(
(In reply to Pacho Ramos from comment #3) > No idea about how could this be solved then :( Whoah, why is this bug still open? It has been a while since all pthread_* has been in uclibc. Take a look at http://git.uclibc.org/uClibc/log/libpthread/nptl/pthread_condattr_setclock.c for just pthread_condattr_setclock()
(In reply to Anthony Basile from comment #4) to be fair, that only applies when uclibc is built with USE=nptl we probably should change the defaults for at least x86 ... i only recently unmasked that USE flag for all of uclibc ...
