fatal error: type_traits: No such file or directory

[w2016561536]

When i tried to compile for esp32s3, the c++ headers file <type_traits> could not be found. However cmath, cstdio, cstring could be found normally.

Compiler version: esp-13.2.0_20230928
OS: Ubuntu 22.04.3 LTS on 5.15.133.1-microsoft-standard-WSL2

Compile command:

I think the issue is that there is -nostdinc++ on the command line, so <type_traits> doesn't get found.

If you remove -nostdinc++, the header should get found correctly: https://godbolt.org/z/dKTfTTqvK
