How to use compile GTK in C on Mac OS

Question

I'm getting started in c and would like to create GUI, so I tied using GTK.

I followed the tutorial they gave on https://www.gtk.org/docs/getting-started/hello-world/ , but when I get to compiling, I get this error:

--libs gtk4` -bash: pkg-config: command not found hello-world-gtk.c:2:10: fatal error: 'gtk/gtk.h' file not found #include <gtk/gtk.h>

how do I fix this!!! I downloaded it and everything, but it still doesn't work!

BTW the command used to run is: gcc main.c -o p1 pkg-config --cflags --libs gtk+-2.0

not sure if this has anything to do with it.

the main.c is in the desktop, and I made sure to cd to it, so that can't be the problem.

The error suggests that gtk.h can't be found in the typical include directory (/usr/local/include) or the current directory. Run

find /usr/local/include . -name gtk.h

to verify you actually have the gtk.h file. If you do, you may need to move it. If not, you need to download the file.
