im new to system programming, idk if thats the issuse. but according gcc, it can not find dbus/dbus-arch-deps.h and thats all i know. any idea about this issue?

 program
[I] tomri@artix ~ [1]> cat main.c
#include <dbus-1.0/dbus/dbus.h>

int main(void) { return 0; }

# error
[I] tomri@artix ~> gcc main.c
In file included from main.c:1:

    % pkg-config --cflags dbus-1
-I/usr/include/dbus-1.0 -I/usr/lib/dbus-1.0/include
% pkg-config  --libs dbus-1
-ldbus-1

    gcc main.c `pkg-config --cflags --libs dbus-1`

    You don’t need to link against the library yet, but you will.

    Linking might become a separate step when you have multiple files, not just main.

      thanks! this allows me compile my program with no error. why gcc couldnt do this automatically? i mean its supposed to do this right? and another important issue that clang ls (language server) showed the same error? i thought fixing this would fix that too, but that isnt the case here. without clang ls running i wont get any auto completions. thanks again
