Bug 5728 – Feature Request: Enable posix threads for db-3/db-4

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Nicholas Wourms 2002-07-29 10:32:41 UTC]

Since linux has a wonderful pthreads library, why not enable posix mutexes for 
enhanced performance?  This would be obtained by adding the line "--enable-
posixmutexes" to the ebuild.

Jon ?

Sure, why not?
Try it, build a complete system, and give it a go.
If it works, let us know. ;-)

Well so far, I'm experiencing some "bugs" during the configury stage.  The
symbols necessary are defined in the pthread library and header, but the
autoconf macro isn't linking against -lpthread eventhough it recognized that I
have -lpthread.  Therefore, it is currently generating a false negative for
posixmutexes.  Fortunately, I had to hack the various db packages recently for
the Cygwin port, so I'm intimately familiar with the configure scripts for db. 
I'll report back when I have this resolved.

This can only be done with NGPT, or maybe NPTL if out, marking a later.
