David, Thanks for the reply. I updated both gimp and gmic from git, recompiled, and now I see the original error…aargh.
gmic_gimp_gtk.cpp: In function ‘void create_dialog_gui(bool)’:
gmic_gimp_gtk.cpp:4087:57: error: ‘GIMP_STOCK_RESET’ was not declared in this scope
** GIMP_STOCK_RESET,GTK_RESPONSE_NONE);**
