nodejs22 @22.12.0_0: error: invalid value 'gnu++20' in '-std=gnu++20'

[axoide (cborg)]

After running the command "sudo port upgrade outdated", nodejs port update failed.

-nR upgade --force, clean, uninstall and re-install nodejs22 did not solve the problem. Here is the error message in the terminal:

Error: Failed to build nodejs22: command execution failed

The error in the log is:

This is surprising. MacPorts has chosen MacPorts clang 17 and according to CompilerSelection MacPorts clang 16 and later (and Apple clang 15 and later) support C++20.

The port says compiler.cxx_standard 2017. If it now requires C++20 that line should change to 2020 but that won't fix this problem.

The log shows that it is using MacPorts clang 17 as the C compiler but Xcode clang as the C++ compiler. Fixing that should fix the problem.

I have a different issue. I don't understand why it's looking for cstring with a C compiler.

(I'm on Sonoma 14.7.1, with mac ports 2.10.5)

[akimd (Akim Demaille)]

I fully reinstalled Xcode, and it fixed all my issues (with boost176, nodejs22, mysql8).

@akimd, your problem was ProblemHotlist#clts16, unrelated to this ticket.

[akimd (Akim Demaille)]

Ah, good to know. Thanks Ryan!
