Usually this would be fixed by adding this line to the port:

compiler.thread_local_storage yes

This instructs MacPorts to select a compiler that supports thread-local storage.

Addressed with ​https://github.com/macports/macports-ports/pull/19586

In 6b221823bad0ffc9f430a615683d072cc6e9620e/macports-ports (master):

postgis3: use compiler supporting thread-local storage

Closes #67781

[nilason (Nicklas Larsson)]

We need to reopen this,

compiler.thread_local_storage yes

didn't do the trick, unfortunately.

​https://build.macports.org/builders/ports-10.10_x86_64-builder/builds/233048/steps/install-port/logs/stdio

From configure log, this is what is executing the C++ code, which fails:

C++ compiler (Wagyu): /usr/bin/clang -std=c++11 -x c++ -pipe -Os -stdlib=libc++ -arch x86_64
