Linux pthreads for AMD64

[Johnson Mpeirwe]

Thanks, I meant non-NPTL threads which were working very well with MySQL 5.1 on a 32bit FreeBSD 6.2 installation. I was looking for a FreeBSD thread library that I can try other than libthr.

Regards,
Johnson

After running into performance issues (MySQL is painfully slow) when compiled with FreeBSD's native libthr, I have tried recompiling with the libpthread library but failed as follows:

    Do you mean NPTL threading or non-NPTL (linuxthreads) threading?
If you meant the latter, that should be dead and gone by now (it has
been dead for quite some time in glibc at least...).
