1. gtklib
Two questions:
1. If I make a program using gtklib, is it supposed to work on both Linux
and Windows?
2. When I try to run the examples on Windows (changing the extender from
exu to exw), they don't work. I get an error message:
gtklib.e: 40 in procedure gtk_init()
c_proc/c_func: bad routine number (-1)
called from gtklib.e: 620
What's with that?

It works on my machine, but only if you have the correct DLLs loaded. You
can find the current versions for Windows at:
http://user.sgic.fi/~tml/gimp/win32/
It's been a *long* time since I've tried the code. There's a chance that the
GTK library structures have changed since then (this is a know problem with
dynamic linking, and with GTK in particular).
I suspect that it will work, but you'll need to change the version number of
the DLL - it's probably several versions past 1.3.

The error message tells you that the call to c_proc failed because it had a
"bad routine number" of -1. If you check the dump, you'll see that gtk_init_
has a value of -1.
gtk_init_ is set a couple of lines above, with a call to link_c_proc, which
is basically a thin wrapper around define_c_proc. A value of -1 means that
define_c_proc wasn't able to find the routine "init_gtk" in the dll.
If you look further, I'll bet that the value of GTK and GDK are zero. The
documentation notes that they have a value of zero if Windows can't find the
DLL.
So basically, you tried to link routines in DLLs that weren't there, but
because my code doesn't have good error checking, you didn't get an error
until you finally tried to link to a function.
Download the current DLLs, place them in the same directory as the code, and
change the name of the DLLs from "1-3" to whatever they currently are, and
it should work.
I hope this helps!

3. gtklib
Mostly for Irv Mullins, but for anyone who has any experience of the
library.
What assumptions do you make re the requirements to run the library.
I seem to have gtk 1.2.8 installed (SuSE Linux system) - are there any
other requirements?
I can get the graphapp euphoria library to work.
Chris.

Hi Chris:
You'll need libgtk and libgdk, plus the little eugtk.so supplied with the
package. I don't think the version matters a lot, I'm not using any
bleeding-edge stuff here.
So far, I've had no problem running this in Mandrake 7.1, 8.0, 8.1, RedHat
7.1, SuSE 6.4, or TurboLinux (something or other).
Anyway, if you want to test to see if you can actually run any gtk programs,
copy the following code and save it as gtkwin.c:
/* Basic GTK+ app */
#include <gtk/gtk.h>
gint main (gint argc, gchar *argv[])
{
GtkWidget * TheWindow;
gtk_init( &argc, &argv);
TheWindow = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_widget_show(TheWindow);
gtk_main();
return 0;
}
Next, compile it using
gcc gtkwin.c -o gtkwin `gtk-config --cflags --libs`
(Note: Those are back-tic's)
If it compiles, the needed libraries must be there.
If not, let me know what the error messages are.
Regards,
Irv

Tried the compile with back ticks (as I should have done) - it compiled
without any errors, so all the requisite parts of the gtk library appear to
be there (can't test the window it produces, but I suspect it will produce
one, since my (obviously) idiot compile method produced one. I will confirm
it produces the test window tomorrow (sorry I'm at home at the moment, just
compiled it using a dial in)
I did try to run the gtk demos from an xterm (well konsole actually, looks
nicer), but they just did nothing (actually used mc, with pause after run set
on to make sure I don't miss anything exciting) - they didn't produce any
errors or anything. KDE 2 incidentally.
By the way, my curiosity is now piqued - what does `gtk-config --cflags
--libs' do ?
I think my monitors dying. Better go. Sorry to be so much trouble.
Chris.

I think I know what the problem is. libgtk has multiple dependencies
(about a dozen) and each of those has its own dependencies.
No doubt you are missing some library files that are needed.
Rather than trying to track them all down, which could take days,
why not just reload Mandrake. Choose "expert" mode, and select
"Development Station" (something like that) as well as any others
you want. (Web server, etc). Be sure to choose both Gnome and KDE
as your GUI's of choice. That should load everything you need, as
Elias pointed out.

It's a program that returns a list of the libraries and where they're located.
Much easier than typing in:
-I/usr/include/gtk-1.2 -I/usr/include/glib-1.2 -I/usr/lib/glib/include
-I/usr/X11R6/include
-L/usr/lib -L/usr/X11R6/lib -lgtk -lgdk -rdynamic -lgmodule
-lglib -ldl -lXi -lXext -lX11 -lm
