Hostname on esp32

[lorenzo-pirchio]

Hi,
I'm developing a xmpp client for esp32 using rust.
But I have problems with the dependencies, especially with this crate.
When I compile the project I get this error generated by the linker:
note: [ldproxy] Running ldproxy
Error: Linker C:/.embuild/espressif/tools/xtensa-esp32s3-elf/esp-2021r2-patch5-8.4.0/xtensa-esp32s3-elf/bin/xtensa-esp32s3-elf-gcc.exe failed: exit code: 1
STDERR OUTPUT:

I'm trying to add esp-idf-sys::gethostname instead of libc::gethostname but I have been having a lot of difficulties due to lack of documentation
