Thanks, I figured as much. I just thought I remember being told at one point that gdb's thread support on FreeBSD had improved. Given a choice between adding thread support to GDB myself and developing my application on NT, which by the way has very good thread debugging support on MSVC6.0. I think I would rather just spend a weekend adding support to GDB. -Kip On Wed, 15 Sep 1999, f.johan.beisser wrote: > > sorry folks, i passed this on to someone who should know.. > > jan > > ---------- Forwarded message ---------- > Date: Wed, 15 Sep 1999 17:07:33 -0400 (EDT) > From: Chris Doherty <cdoherty@wopr.skidmore.EDU> > To: f.johan.beisser <jan@caustic.org> > Subject: Re: does gdb on 3.3RC have thread support?
