[reneeotten (Renee Otten)]

please attach the full log main.log mentioned in the error messageto this ticket. From ​the status page it appears thhe port builds on all systems, where are you trying to install it?

[ryandesign (Ryan Carsten Schmidt)]

Per the ticket description, on x86_64-apple-darwin21.

The original release of gcc8 predates macOS Monterey by several years. Try the gcc-devel port instead for now, until the next stable version of gcc is released.

[cooljeanius (Eric Gallager)]

Also seeing this on Big Sur, so it's not just a Monterey issue
