I wrote up autoconf macros for this here: http://gcc.gnu.org/onlinedocs/libstdc++/17_intro/backwards_compatibility.html See "Support for C++TR1 dialect" I'm waiting on feedback and then hope to merge these into the autoconf macro repository. > Unfortunately, > I will got a message, > that I have to use the -std=gnu++0x if I want to include this header > file. Yes, as <unordered_set> is a C++0x standard header. If you'd like to use C++98, I suggest using TR1's <tr1/unordered_set> best, benjamin -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
