I am trying to use MacPorts on my new air which is necessarily running Big Sur 11.2.3. I have Xcode 12.4 and the Command Line Tools installed. I have installed via the installer and via source but I always get:
Warning: The macOS 11.2 SDK does not appear to be installed. Ports may not build correctly. Warning: You can install it as part of the Xcode Command Line Tools package by running `xcode-select --install'. I have taken tried installing manually via Command_Line_Tools_for_Xcode_12.4.dmg but hasn’t fixed it. Despite the error, I have been able to install a number of things but gcc9 fails with: ---> Computing dependencies for gcc9 The following dependencies will be installed: cctools gcc_select gettext gmp isl ld64 ld64-xcode libgcc libgcc10 libgcc9 libiconv libmpc mpfr ncurses xz zlib . . . ---> Fetching distfiles for libgcc10 Error: gcc10 10.3.0 is not supported on Darwin 20 arm Error: Failed to fetch libgcc10: incompatible OS X version Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_gcc10/libgcc10/main.log for details. Error: Follow https://guide.macports.org/#project.tickets to report a bug. Error: Processing of port gcc9 failed Seems odd to me that gcc9 needs libgcc10. Not sure if these two are related but anyone have any idea what the problem might be? Many thanks Andrew
