Hi, Indeed, gcc8 is not supported on 10.5 or older, and likely will never be.
What is requiring you to use libgcc8 ? You should instead be using libgcc7 on that platform. Note this is what the libgcc port is there for, to set up this dependency correctly. https://github.com/macports/macports-ports/blob/master/lang/libgcc/Portfile Chris > On 24 Sep 2019, at 11:40 pm, Riccardo Mottola via macports-users > <[email protected]> wrote: > > Hi, > > I don't know if it is related to the 2.6 upgrade or it is "just" an upgrade, > but on Leopard 10.5, I get the following: > > ---> Cleaning curl > ---> Removing work directory for curl > ---> Computing dependencies for libgcc8. > ---> Fetching archive for libgcc8 > ---> libgcc8-8.3.0_5.darwin_9.x86_64.tbz2 doesn't seem to exist in > /opt/local/var/macports/incoming/verified > ---> Attempting to fetch libgcc8-8.3.0_5.darwin_9.x86_64.tbz2 from > http://lil.fr.packages.macports.org/libgcc8 > > % Total % Received % Xferd Average Speed Time Time Time Current > Dload Upload Total Spent Left Speed > 0 0 0 0 0 0 0 0 --:--:-- 0:00:04 --:--:-- > 0---> Attempting to fetch libgcc8-8.3.0_5.darwin_9.x86_64.tbz2 from > http://nue.de.packages.macports.org/libgcc8 > > % Total % Received % Xferd Average Speed Time Time Time Current > Dload Upload Total Spent Left Speed > 0 0 0 0 0 0 0 0 --:--:-- 0:00:04 --:--:-- > 0---> Attempting to fetch libgcc8-8.3.0_5.darwin_9.x86_64.tbz2 from > http://fco.it.packages.macports.org/mirrors/macports-packages/libgcc8 > > % Total % Received % Xferd Average Speed Time Time Time Current > Dload Upload Total Spent Left Speed > 0 0 0 0 0 0 0 0 --:--:-- 0:00:04 --:--:-- > 0---> Fetching distfiles for libgcc8 > Error: gcc8 8.3.0 is not supported on Darwin 9 > Error: Failed to fetch libgcc8: incompatible OS X version > Error: See > /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_gcc8/libgcc8/main.log > for details. > Error: Problem while installing libgcc8 > Error: Follow https://guide.macports.org/#project.tickets to report a bug. > > > now... it means I can't have (yet) gcc8... > Maybe we can make the dependency of libgcc less stringgend... or Ken is > already doing some magic for gcc 8 support? > > In my experience, gcc 8 is an evolution of gcc6 which is a "good" compiler, > but gcc8 broke quite some things (like...
