Hi Hazen: As far as I can tell from
git log --follow examples/c/extXdrawable_demo.c Jonathan Woithe implemented that example a decade ago, you did the actual commit, and we have been (minimally) maintaining it ever since. This example is really dated because it contains calls to the GTK+ API that were already deprecated for GTK+ version 2 and non-existent for GTK+ version 3. And it is not a good idea to mix this GTK+ version 2 example with a PLplot core library that can depend directly (in the non-dynamic drivers case) on GTK+ version 3 which has long been the standard version of GTK+. So I have effectively disabled the build of examples/c/extXdrawable_demo.c in my recent commit 9893349d1. I did take a look at porting this example to GTK+ version 3 following the precepts in <https://developer.gnome.org/gtk3/stable/gtk-migrating-2-to-3.html>. For example, after PLplot was built, I built the example directly using cd examples/c gcc ../../../plplot.git/examples/c/extXdrawable_demo.c -DUSINGDLL -I/home/software/plplot/HEAD/plplot.git/include -I/home/software/plplot/HEAD/build_dir/include -I/home/software/plplot/HEAD/plplot.git/lib/qsastime -I/home/software/plplot/HEAD/build_dir/lib/qsastime -O3 -fvisibility=hidden -Wuninitialized $(pkg-config --cflags --libs gtk+-x11-2.0) ../../src/libplplot.so |& less If you try the -DGTK_DISABLE_SINGLE_INCLUDES flag that is recommended in the above URL that works, but as soon as you try the additional recommended -DGDK_DISABLE_DEPRECATED -DGTK_DISABLE_DEPRECATED flags a whole host of issues show up, i.e., porting this example is not going to be trivial. Therefore I abandoned that idea for myself, but I encourage you to take a look at porting this example because I believe your GTK+ skills/experience are a lot more extensive than mine.
