People can rightly expect linking C++ code to work under both BSD-like systems as well as GNUish systems as well as, for example, Solaris/CC where -lstdc++ is spelled "-lCstd -lCrun". Libtool promises to keep the normal user from being exposed to these differences. > is it _always_ needed? what about -lsupc++? Ahh, very good question. Here we have an issue: it should be possible to _override_ the decision of libtool to add -lstdc++ on OpenBSD in all cases. But those cases, in my opinion, would be the exception rather than the rule: they are usually the cause when your package makes use of some system-specifics anyway. (Maybe there is even a way to detect whether supc++ is preferable over stdc++; I don't know of one, though, and in this case guessing is probably worse than allowing an override.) Can we agree on this somehow? What other issues, if any, are you experiencing? Cheers, Ralf _______________________________________________ http://lists.gnu.org/mailman/listinfo/libtool
