HI,

i use the nRF connect SDK v2.0.0 direction fiding RX example in WIN10 VScode with nRF52833dk.

i want  write something like 'fopen' , but the header 'stdio.h'  cannot found.

i have comfirmed it is exist.

error task

the same path header files, but they can use.

when i open the stdio.h , it has error 'toolchain.h'

i found the file in 'llvm-vs-code-extensions.vscode-clangd'. 

path  :C:\Users\user\AppData\Roaming\Code\User\globalStorage\llvm-vs-code-extensions.vscode-clangd\install\15.0.3\clangd_15.0.3\lib\clang\15.0.3\include

stdio.h error task

how can i fix it?  thanks.

Hi

I think the toolchain.h file you're looking for is located in ...\zephyr\include\zephyr. Try to also add CONFIG_NEWLIB_LIBC to your prj.conf fileto enable the use of non-minimal C functionality.

Best regards,

Simon
