1. Irv's GTK Stuff
Irv, I'd love to use your GTK stuff if you'd tell me how to create a
eugtk.so for FreeBSD...
Otherwise, if I take your advice about not using the console, I'd have
to dev in Windows. Now, that's not so bad 'cuz I can use Win32Lib and
Judith's IDE, but I'd rather have something that ultimately will be
x-plat (or easily x-plat).
In that regard, can anybody suggest a simple x-plat graphics package
that already works for Linux/FreeBSD and Windows (and whatever other
flavor of OS you prefer/use)?
In the meantime, I'll be dev'ing for the lowest of the low platforms
'cuz then I know it'll work everywhere. For instance, my EDB Editor
(tentatively named "edbed") works in both FreeBSD and Windows 2000. What
more could a database manipulator want?

I've looked at a lot of cross-platform toolkits, and I'm convinced that
wxWindows is probably the best one you're going to run across. A couple
things that set it apart:
- It uses native controls, not emulated ones
- It runs on Windows, Linux and OS X
- It does a lot more than just widgets
- It works with every compiler out there
- It's actively being supported
For example, it handles printing, file systems, inter-process communications,
databases, and so on. Borland is going to use it for one of their upcoming
projects.
The downside of this is the wxWindows will probably make your application
fairly hefty, even with the use of something like UPX to compress the
executable size. A Windows executable will probably be a bit under 1 Meg, and
a Linux staticly linked executable under 2 Megs.

David,
I have ceased to actively read either the Open Euphoria or the Euphoria
forum, and have been spending what language efforts that I do make these
days on the Icon family of languages, mostly Unicon, though I find Converge
to be a really fascinating "idea". Where are you spending your efforts
these
days. Searching back through the forums, I noted that the last post that
you
made from your government location was at the end of 2001. I assume that
you either quit posting from there, or that you have sought employment
elsewhere. Your talents should be welcome almost anywhere.
At the beginning of December, I am returning to California for a week or
so to celebrate the wedding of my eldest daughter in San Diego. That is
where I married her Mother in 1971, after I had left the Navy. After the
ceremony, I intend to run Route 1 up the coast to SF where I matriculated
at the Navy BEEP school at Mare Island in 1969. From there, I plan to
drive east to Denver to see my other child, and then back to Ingram to
my home. I would be honored if you would allow me to buy you lunch or
a cup of coffee as I pass through your abode. If not, I will understand. I
doubt that I will drive to California again in my lifetime, but you can
never
be sure of these things.
I do hope to hear from you from time to time, as I believe that you are
capable of contributing some interesting things to our shared field through
your energy and capability.

You can compile it with the command:
gcc -Wall -shared eugtk.c -o eugtk.so `gtk-config --cflags --libs`
provided you have the gtk development files installed.
Probably you have those on your BSD cd's , but I don't know if they
were installed automatically. On Mandrake and Red Hat, those libraries
get installed if you chose to set up a 'development' platform, but aren't
installed if you choose some of the other types, such as "graphics
workstation", or whatever. You can always go back and install them later.
If you didn't get the needed files on the BSD cd's, then there's a bit more
work. You'll have to download the source from http://gtk.org, and do some
compiling. Note that there are two versions of GTK 1.x and 2.x. Get 1.x.
Also, note that the gtk-config mentioned in the compile command is a separate
program. You may have to download and compile that first. Also, note that
the 'tick' marks in that line are back-ticks (on the same key as the ~).
Let me know how this works.

It would be a lot easier to learn Python. wxPython works now, without waiting
for Rob or anyone else. I took about 10 minutes to look thru the wxWindows
shared library and decided I had no interest in trying to connect to that with
Euphoria. In addition, since wxWindows uses GTK on Linux, there's no
difference in appearance compared to programs written in plain GTK.
Some of the complex wx controls are nice, but you could write your own
as Euphoria includes if you really needed them. And a few of the wx controls,
such as the calendar, are ugly compared to the GTK originals.

If I remember correctly about my looking at Python, Python sucks... Of
all those "other" languages, I think I liked Ruby the most. However, I
won't be going elsewhere anytime soon...
Unless... of course... I need to. :/

I thought some of the Linux screenshots looked similar in appearance to
your GTK stuff. :)

Okay, looks promising... I get this output when I type in the above command:
eugtk.c: In function 'GetEUID':
eugtk.c:464: warning:implicit declaration of function 'geteuid'
i do have a eugtk.so file now... does that mean it was a success? what
about that error message?

Well, there's wxLua, wxPerl, wxBasic... even wxEuphoria.
It would be a lot easier to write wxEuphoria by adding it into the Euphoria
source than to write a DLL to link to. For example, you'd probably want
Euphoria to keep track of objects and manage their lifetime.
If I were to do it, I'd probably wrap wxWindows objects in a sequence
containing something like:
{ MagicNumber1, MagicNumber2, pointer, class, temp flag }
and then hack Euphoria's sequence destructor so that it would check to see if
the sequence was in that form, and if so, call the pointer's destructor if
the temp flag was set to true. That way, you would get reference counting on
the pointers for free.
The wrappers might looks something like this:
wxCall( wrapped pointer, function name, { args } )
If anyone is interested in this, I've got from my own projects that could be
used for this.

(I see in Euman's forum, you posted more details, so I reply here to both)
I don't know where to begin with this. One thing might be to find out whether
the problem is with the Euphoria part, or with the GTK setup. To do that,
you could try to compile and run a GTK program written in C.
Go to http://gtk.org and choose the 2.0 tutorial. Pick a couple of example
programs from that tutorial and compile them. If they work ok, then we
have to look at the libraries that Euphoria calls.
You could write a little eu program which just opens a single library, and
try each in turn until you see which one causes the error.

Thanks, Irv... I'll try tonight and let you know. What's your preferred
path of contact, preferably an IM client of some sort. :)

I've looked at wxEuphoria, although I haven't played with it yet. There were
some sort of dire warnings that I was paying attention to... 
I was under the impression that you had this Real Ugly Hack (tm) that you had
to do in order to resolve addresses in the DLL. Has this been replaced by
something elegant?

OK, I'll have a look at it.

Compiled "hello_world.c" and it worked! woo hoo!
Compiled their "scribble" program and it worked too! yiiiippeeee!

Irv, I tried running the simplest program you have: window.exu. It
errored out with this:
$exu window.exu
/usr/libexec/ld-elf.so.1: /usr/local/lib/libintl.so.5: Undefined symbol
"stpcpy"
First, am I running it right with "exu window.exu?"
Second, ....
Third, I guess I could turn my EU program into a .c file with the
EU-to-C program, then compile with gcc... right? :)

Probably not.
If I recall correctly, you're using GTK 2.2? If so, try this test and let me
