Can you check if you have the LIBCLANG_PATH environment variable set, that variable must be set by sourcing the environment file, see https://esp-rs.github.io/book/installation/index.html#3-set-up-the-environment-variables

[Horryportier]

LIBCLANG_PATH is set to $HOME/.rustup/toolchains/esp/xtensa-esp32-elf-clang/esp-16.0.0-20230516/esp-clang/lib

[SergioGasquez]

LIBCLANG_PATH is set to $HOME/.rustup/toolchains/esp/xtensa-esp32-elf-clang/esp-16.0.0-20230516/esp-clang/lib

Are you building the project in the same terminal where you source the export file or print the LIBCLANG_PATH? Also, check the content of that folder just in case is empty (?)

[Horryportier]

found out $HOME/.rustup/toolchains/esp/xtensa-esp32-elf-clang/esp-16.0.0-20230516 is empty

Try reinstalling the environment with espup, do you remember having any issues during the installation?

[Horryportier]

i think i might had to stop command in the middle one time for some reason

[SergioGasquez]

I will be closing the issue, feel free to reopen the issue if you encounter any issue after reinstalling.

See https://github.com/esp-rs/esp-idf-template/issues/139. It should be fixed by adding a patch for esp-idf-svc .
