How to include GTK header files

How to include GTK header files#

This is using clangd with the gcc compiler.

Error: ('gtk/gtk.h' file not found)#

#include <gtk/gtk.h>

int main (void) {
  return 0;
}

Solution#

In order to fix this, there has to be a clang.cfg with the location of the associated libraries.

Command

pkg-config --cflags gtk4

Output

-I/opt/gtk/include/gtk-4.0 -I/usr/include/pango-1.0 -I/usr/include/harfbuzz -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/cairo -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/freetype2 -I/usr/include/graphene-1.0 -I/usr/lib/graphene-1.0/include -mfpmath=sse -msse -msse2 -I/usr/include/libmount -I/usr/include/blkid -I/usr/include/fribidi -I/usr/include/sysprof-6 -pthread -I/usr/include/libpng16 -I/usr/include/pixman-1

Then using VIM commands format the string to this (filename: clang.cfg):

CompileFlags:
  Add: [
    "-I/opt/gtk/include/gtk-4.0",
    "-I/usr/include/pango-1.0",
    "-I/usr/include/harfbuzz",
    "-I/usr/include/gdk-pixbuf-2.0",
    "-I/usr/include/cairo",
    "-I/usr/include/glib-2.0",
    "-I/usr/lib/glib-2.0/include",
    "-I/usr/include/freetype2",
    "-I/usr/include/graphene-1.0",
    "-I/usr/lib/graphene-1.0/include",
    "-mfpmath=sse",
    "-msse",
    "-msse2",
    "-I/usr/include/libmount",
    "-I/usr/include/blkid",
    "-I/usr/include/fribidi",
    "-I/usr/include/sysprof-6",
    "-pthread",
    "-I/usr/include/libpng16",
    "-I/usr/include/pixman-1"
  ]
