 I have tried to build gtkglext +quartz without success.
 I attach the main.log file. I have encountered this when trying to build
 gwyddion in an isolated installation of macports. (/opt/gwyddion)

 The error is in gdkglshapes I think. By accesing the work path of the
 build and running make I obtain:

 {{{
 gdkglshapes.c:552:12: error: redefinition of 'index' as different kind of
 symbol
 static int index[20][3] =
 }}}

 My os and xcode version:\\
 xcode version 9.2\\
 macOS 10.12.6

Comment:

 It seems that gtkglext's use of a variable named `index` is conflicting
 with a function named `index` that is provided by the operating system. I
 am surprised that the operating system would provide a function with such
 a generic name, and that this problem was not observed before, but I can
 confirm the problem on my Sierra system.
