@williamtcdns trying the above west command, the sample builds fine for me, can you share more information about your environment?

[nashif]

are you build with gcc or the xtensa toolchain?

[williamtcdns]

We use patches that allows us to build with recent xtensa toolchain which uses clang.

Does your toolchain built with wide character support?

[dcpleung]

Note that I have built with xt-clang (RI-2022.10) where picolibc was built from source, and there was no errors related to wint_t.

Does your toolchain built with wide character support?

How can I tell whether toolchain was built with wide character support ?

I am using RJ-2024.3

[dcpleung]

I am not sure. You will need to look at the configurations that are used to build that toolchain.
