  • SR-145 Need a way to add include paths in modulemap

Issue Description:

When trying to include gtk.h from a module, swift complains it can't find gdk.h

<module-includes>:1:10: note: in file included from <module-includes>:1:
#include "/usr/include/gtk-3.0/gtk/gtk.h"
         ^
/usr/include/gtk-3.0/gtk/gtk.h:30:10: error: 'gdk/gdk.h' file not found
#include <gdk/gdk.h>
         ^
main.swift:1:8: error: could not build Objective-C module 'CGtk'
import CGtk

gtk.h sits in /usr/include/gtk-3.0/gtk/gtk.h and gdk.h is in /usr/include/gtk-3.0/gdk/gdk.h

I've tried with package manager and directly using swiftc, I've created a module for gdk, nothing works and it swift still cannot find gdk/gdk.h

In fact the problem here is GDK needs its own module.

You can work around this by adding GDK to the same module map:

module CGTK [system] {
    header "/usr/include/gtk-3.0/gtk/gtk.h"
    link "gtk-3"
    export *
}

module CGDK [system] {
    header "/usr/include/gdk-3.0/gdk/gdk.h"
    link "gdk-3"
    export *
}

As specified in the documentation, module map dependencies must be specified all the way down.

It's possible that SE-0063 can also help here.
