virt-viewer @7.0 Failed to build libgcc11: command execution failed

[soundpassion]

Hi all,

I must say at the beginning that i'm not a guru in these kind of things so please be patient if I ask no sense questions. I'm trying to install virt-viewer port ​https://ports.macports.org/port/virt-viewer/ on macOS Monterey 12.0.1 on a mac mini M1. I followed the guide on this link https://www.macports.org/install.php before to execute the installation command for virt-viewer port.

I got an error during the installation of virt-viewer port on libgcc11 build execution, I already checked "Problem Hotlist" and did port clean).

Error: Failed to build libgcc11: command execution failed Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_gcc11/libgcc11/main.log for details. Error: Follow ​https://guide.macports.org/#project.tickets if you believe there is a bug. Error: Processing of port virt-viewer failed

Looking into the main.log file I see:

and looking into config.log I see

I read old threads on the web regarding gcc and Clang but they were referring to old OSX versions so I'm not sure that was the same case.. Anyway this is the output of gcc --version command:

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/4.2.1

Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

I attach both main.log and config.log files.

Thank you in advance for your support.

Best regards
