I tried to follow Jeff's suggestion - installed fresh new gtkada2.8
from adacore, then installed fresh Win_IO 3.0 from its source.
Sorry to say, result is very much as I recalled from nearly a year
ago:
test_plot_window compiles and links OK, but the elaboration of
Plot_Window_Type:=Plot_Window("Test Plot Window","Degrees","Value");
at the very beginning of that test program results in:
(test_plot_window.exe:4076): GLib-GObject-WARNING **: gsignal.c:1268:
parameter 2 of type `<unknown>' for signal
"GtkPlotCanvas::select_item" is not a value type
(test_plot_window.exe:4076): GLib-GObject-WARNING **: gsignal.c:1268:
parameter 1 of type `<unknown>' for signal "GtkPlotCanvas::move_item"
is not a value type
(test_plot_window.exe:4076): GLib-GObject-WARNING **: gsignal.c:1268:
parameter 1 of type `<unknown>' for signal
"GtkPlotCanvas::resize_item" is not a value type
(test_plot_window.exe:4076): GLib-GObject-WARNING **: gsignal.c:1268:
parameter 1 of type `<unknown>' for signal
"GtkPlotCanvas::delete_item" is not a value type
(test_plot_window.exe:4076): GLib-GObject-WARNING **: cannot retrieve
class for invalid (unclassed) type `<unknown>'
raised PROGRAM_ERROR : EXCEPTION_ACCESS_VIOLATION
-------------------------------------------------
(Some) other parts of the library appear to work properly.
I'd welcome some advice on this...
John
