The default threading package when building in the ports system is PTHREAD_LIBS. You can't make -pthread select that. PTHREAD_LIBS can be overridden in /etc/make.conf or the environment. If you want to argue between which you'd prefer, PTHREAD_LIBS or -pthread, that's fine, but PTHREAD_LIBS is what we currently have and what I'm going by. > It is insane to have FreeBSD be different than all other systems for > this trivial reason.

Allowing -pthread to be a noop doesn't necessarily solve the problem right now. Ports check for -pthread and use it without also using PTHREAD_LIBS, so they would still be broke. Ports that are libraries that use -pthread won't break when -pthread is NOOP'd, but non-threaded applications that use those libraries may fail to link. -- Dan Eischen _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"
