// These are internal fltk symbols that are necessary or useful for
// calling Xlib.  You should include this file if (and ONLY if) you
// need to call Xlib directly.  These symbols may not exist on non-X
// systems.

There are macros further on that use XCreatePixmap in their definition:

#   define fl_create_offscreen(w,h) \
  XCreatePixmap(fl_display, \
              (Fl_Surface_Device::surface()->class_name() ==
Fl_Display_Device::class_id ? \
              fl_window : fl_xid(Fl::first_window()) ) , \
              w, h, fl_visual->depth)

So I'd say that fltk apps that use this header really do need to specify
-lX11 in their own LDFLAGS as they will need these symbols directly.

So it's an flrig bug.

It's easy to work around:

$ LDFLAGS="-lX11" ./configure && make
[...]
$ ldd src/flrig
	linux-vdso.so.1 =>  (0x00007fffccb82000)
	libX11.so.6 => /lib64/libX11.so.6 (0x0000003c77600000)
[...]

I couldn't see where to report bugs on w1hkj.com...

Regards,
Bryn.

So why does this bug not show itself on Suse, and any of the Debian based builds?

So it seems to be down to the fact that flrig includes &lt;FL/x.H&gt;:

$ fgrep 'FL/x.H' rig.cxx
#include &lt;FL/x.H&gt;
#include &lt;FL/x.H&gt;
