It appears that the boost-1.34.1 package is building multiple library variants; specifically, both thread-safe and non-thread-safe versions of each library get built and installed. This is a departure from the boost 1.33.1 package, where only the thread-safe variants of the libraries were built and installed. Is this change deliberate? Do we really need the non-thread-safe variants? This change has some unfortunate consequences. First of all, since there is no non-thread-safe variant of libboost_thread, there is no more libboost_thread.so. So someone trying to link with that library (which existed in the boost 1.33.1 package) will fail. But this isn't the worst of it. Someone linking with, for instance, -lboost_regex will now get a variant of the library that *is not* thread-safe--where with boost-1.33.1 the same -l flag links to a library that *is* thread-safe. -- Braden McDaniel e-mail: <braden@xxxxxxxxxxxxx> <http://endoframe.com> Jabber: <braden@xxxxxxxxxx> -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
