== Switching to Libc++ on older systems by default == Wiki page for the setup: [wiki:LibcxxOnOlderSystems Libc++ on older systems] Tickets to be addressed: * [[TicketQuery(id=50448|55471|53634|56041)]] See also: * [[TicketQuery(id=52000|49903)]] cxx_stdlib might need to be one additional criteria to respect when selecting an archive site here: * https://github.com/macports/macports-ports/blob/master/_resources/port1.0/fetch/archive_sites.tcl * https://github.com/macports/macports-base/blob/995dde8476c48580db4f6eedfde09e90dc5e8c99/src/package1.0/portarchivefetch.tcl#L66 Then the archive site would no longer be used if anyone changes the default in macports.conf. === Call with Joshua * Make cxx_stdlib to be respected in selection of archive_sites (that would prevent users from downloading binaries rev-upgrade will mark as broken anyway) * #56053 * Offer two separate sets of binary archives for the migration. That would provide a smoother transition, but could also be avoided to reduce effort spent. * Move existing binary archives to a subdirectory (or new binaries in a subdirectory) * List both archive_sites in the ports_tree for the older systems (base will select the one that matches configuration) * Josh to file a ticket to remind us to finish up what we need to improve bootstrapping for C++11 on older systems in time for 2.5.0 #56041
