There's nothing wrong with manual detection - see how Varnish does it: http://varnish.projects.linpro.no/browser/trunk/varnish-cache/configure.ac Note that the correct idiom according to POSIX is -lpthread, so that should in theory work on all POSIX platforms. The reason why Varnish checks for -lthr explicitly is that there are FreeBSD versions where -lpthread defaults to -lkse instead of -lthr, and -lkse has proven to break rather badly under load.
