Failed to fetch libgcc8: incompatible OS X version

[prtouatisid (S. Touati)]

Hello, I am trying to solve this problem since many weeks, without success. I did "port selfupdate ; port upgrade outdated". The error message is: ---> Attempting to fetch libgcc8-8.3.0_5.darwin_19.x86_64.tbz2 from ​http://nue.de.packages.macports.org/libgcc8 ---> Attempting to fetch libgcc8-8.3.0_5.darwin_19.x86_64.tbz2 from ​http://lil.fr.packages.macports.org/libgcc8 ---> Attempting to fetch libgcc8-8.3.0_5.darwin_19.x86_64.tbz2 from ​https://packages.macports.org/libgcc8 ---> Fetching distfiles for libgcc8 Error: gcc8 8.3.0 is (currently) not supported on Darwin 19 Error: See ​https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90835 for more details Error: Until the issue is addressed in Xcode, please instead install gcc9 / libgcc9 Error: Failed to fetch libgcc8: incompatible OS X version Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_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.

My OS versions is macOS Catalina v10.15.1

I installed gcc9 and , and uninstalled gcc8 and libgcc8, but the problem with gcc8 still appears when I execute "port upgrade outdated". I also reinstalled xcode, and the command line tools, without success.

Maybe I am doing something wrong. I enclose the log file. Any help ?

Thanks
