This is now BZ 250802. > 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. Yes. This matches upstream behavior. There has been some discussion of this upstream issue (see boost-build in January, others), but no resolution. > This is a departure from the boost 1.33.1 package, where only the > thread-safe variants of the libraries were built and installed. Yes. > Is this change deliberate? Do we really need the non-thread-safe > variants? This change is deliberate. The way boost is currently structured, both are needed. > 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. boost users expecting thread safe libraries now have to use the -mt.* versions. -benjamin -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
