I'm new at C and started to learn how to create GUI. For some reason the only way program run is
gcc simple.c -o simple -lgtk-3 -lgdk-3 -latk-1.0 -lgio-2.0 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lcairo-gobject -lpango-1.0 -lcairo -lgobject-2.0 -lglib-2.0 -pthread -I/usr/include/gtk-3.0 -I/usr/include/atk-1.0 -I/usr/include/at-spi2-atk/2.0 -I/usr/include/pango-1.0 -I/usr/include/gio-unix-2.0/ -I/usr/include/cairo -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -I/usr/include/harfbuzz -I/usr/include/freetype2 -I/usr/include/pixman-1 -I/usr/include/libpng12
If i just run gcc simple.cit gives me

If I do other 'traditional' ways to include lib:
gcc `pkg-config gtk+-2.0 --cflags` example.c -o example `pkg-config gtk+-2.0 --libs`
It gives me:
Package gtk+-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-2.0.pc' to the PKG_CONFIG_PATH environment variable
No package 'gtk+-2.0' found
graphical.c:1:21: fatal error: gtk/gtk.h: No such file or catalog
What is the right way to include GTK?
I just figured out what was the problem.
I had linuxbrew installed and for some reason pkg-config took path from one of it's repos even if I force it to export. I completely removed linuxbrew and now it's finally working!
