Just an idea (I hope this hasn't been said before in the mega thread but at least I didn't get it this way): - fix all ports to respect PTHREAD_LIBS _ON THE LINKING STAGE_ (so no global search & replace, for it shouldn't be used in compile command line= s) - keep '-pthread' as a compiler option, which maps to a NOOP for compiling and '-lpthread' (aka libkse) for linking - set PTHREAD_LIBS to the default value of -pthread - allow PTHREAD_LIBS to be set to something other, e.g. '-lthr', in /etc/make.conf (or the make command line) What is the problem with this approach? You get both a 'standard' -pthread knob, _and_ the ability to select your threads library using ports. Third party apps that use -pthread will work. The only case in which some work has to be done by a FreeBSD user is when they want to link a non-ported third-party app with a library other than libpthread (libkse). --Stijn --=20 "Linux has many different distributions, meaning that you can probably find one that is exactly what you want (I even found one that looked like a Unix system)." -- Mike Meyer, from a posting at questions@freebsd.org --XOIedfhf+7KOe/yw Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (FreeBSD) iD8DBQE/cTM/Y3r/tLQmfWcRAjXTAJ90joiJrbS+t2lOnzXqCh0raCaC3gCfQscN kq+ntX2jVxm6LqwY846kBEg= =SCsI -----END PGP SIGNATURE----- --XOIedfhf+7KOe/yw--
