1. wxEuphoria v0.10.0 - wxeud.e:758
I installed (or tried to install) wxEuphoria v0.10.0 for Ubuntu.
I'm running Ubuntu Feisty.
I installed all the wxWidgets 2.8 stuff in the Synaptic Package Manager.
I even re-booted in case that would make a difference.
This is what happened when I tried to run hello_world.exw.
exu hello_world.exw
..../wxeud.e:758 in function next_event()
A machine-level exception occurred during execution of this statement
... called from /home/jstory/euphoria/include/wxEuphoria/wxeud.e:772
What did I do wrong?

That shouldn't happen. Just what you wanted to hear, right? That error
usually means that it couldn't open the shared library, but I added some
code to check for that case and abort, so it shouldn't have gotten that
far if that were the problem.
Those lines seem off. Are you running the v0.10.0 release (i.e., not the
beta or alpha) or did you modify the file at all? Also, what are the values
for
* wxWidgets (the atom that holds the handle to the shared library)
* wx_event_type (the c_var that stores the values for the events)
The other thing you could check is to run ldd on the shared library, to
see if it might be having problems linking. The default binary build
might not work if you don't have the same versions of everything, and
would require a rebuild on your machine.

I think you need to compile wxWidgets to get those libraries.

Well, those are all of the wxWidgets libraries that I link to. Maybe
the synaptically-installed files are named something else. Try running
"wx-config". This should give you some information on where your
wxWidgets libraries are installed.
You could also try ./configure && make for libwxeu.so after that.

I don't know how to use wx-config.
Typing it and pressing return just gives me a bunch of info
about wx-config that I'm not smart enough to understand.

After all this stuff is figured out, the next step will be to automate the
installation of wxEuphoria together with dependencies, like with apt-get.
Otherwise most people (especially non-Euphoria people) trying to get a
wxEuphoria-based program to work will quickly give up.

Could you please post the output. It might help me understand and make
it work better. Specifically, try:
$ wx-config --list
and

One thing I note is the wxWCharBuffer. It looks like it's a unicode
version of wxWidgets, which kinda makes sense, except that wxEuphoria doesn't
use unicode. Based on that, I suspect that the names of the shared
libraries are different, so that there's not any conflict. I'll have to
look into this, to see how difficult it will be to build everything with
unicode, which should make it compatible with the distro default.

Yeah, although I think it's pretty obvious now that it's the unicode thing
that's the real problem. I do have a solution in the pipeline that I think
will work for just about everyone. I'm looking into making a build of
euphoria (interpreter and translator + runtime) that statically links
with wxWidgets/wxEuphoria. It'd make for a monstrous executable (3-7MB),
but it would contain all of the wxWidgets stuff, so that the external
dependencies would be minimized, to basically libc++ and gtk2.
I've got a ways to go before there's something useful, and I'm right in the
middle of moving and being very busy at work...

Jerry,
I tried building with unicode, and connecting to the stock Feisty libs.
It seems to work. I've posted the binary for you (or anyone else who's
interested) to test. If this works, I'll make a real distribution of this:
http://wxeuphoria.sf.net/libwxeu.so.tar.gz
Note that it doesn't really "do" unicode in euphroria, although that's
possible, and probably not too difficult. I suspect that this will happen
in a not too distant future release, but I'd like to get some feedback
on that first.
Anyway, try that out, and see if it works for you. BTW, you can't simply
build on your machine, because there were a couple of changes that needed
to be made in the source.

I put that in /usr/local/bin
Then I did
sudo ldconfig /usr/local/lib
(whatever that is supposed to do)
Still didn't work.
I rebooted. Still didn't work.
Same error message as before.

OK, so it's finding the libraries. The fact that you're getting the error
you're getting, however, leads me to believe that you're not running the
most current version of wxeud.e.
The following should be near the top of wxeud.e. If it isn't, then you
aren't using the latest. This code makes sure that if it can't link to
the shared library, it prints an error message and aborts. If you *are*
using the latest, then we have some more work to do. I guess, let's
figure out if *anything* is being properly defined through define_c_*.
atom wxWidgets
if platform() = LINUX then
wxWidgets = open_dll( "libwxeu.so" )
else
wxWidgets = open_dll( "libwxeu.dll" )
end if
if wxWidgets = 0 then
puts(2, "Could not open wxEuphoria library. Press enter to abort.\n" )
if atom(gets(0)) or 1 then
abort(1)
end if
end if

The code you posted looks like it's not the latest version. You can get it
directly from the repository from here (the 0.10.0 tag):
http://wxeuphoria.svn.sourceforge.net/viewvc/*checkout*/wxeuphoria/wxeu/tags/v0.10.0/wxeud.e?revision=120
Try that. If it doesn't work, then before it gets to the crash, put in
a few statements like:
? wxWidgets
? wx_event_type
Let's try to see where the problem is.

OK, so for some reason, open_dll is failing. IIRC, when you ran ldd
on libwxeu.so, it was able to find all of the libraries. Try running
ld-linux.so. In RHEL, it's in /lib. Check the man page for ld.so for
more details.
It can give more information on why it's failing to load. First try without
an absolute path, so see if it finds it. If it doesn't, then the problem
may be that ldconfig didn't run properly. Then try an absolute path, to
see if it loads.
Based on your previous results with ldd, however, I suspect it's a
configuration issue that we need to fix.

I seem to not have ld-linux.so but I have ld-linux.so.2

You have invoked `ld.so', the helper program for shared library executables.

Yep, that's the one. Sometimes there's a symlink. I think it depends on

Maybe we can get back to solving the problem with wxEuphoria v.10.0
for Ubuntu. Is there something you want me to do with
/lib/ld-linux.so.2 ?

Yes, run it with libwxeu.so as the argument. It should try to load the
shared library, and if it fails, it should give a better error message
than "failed to load."

Try specifying the full path:
$ /lib/ld-linux.so.2 /usr/local/lib/libwxeu.so
If that works, then the problem would seem to be that ldconfig wasn't
run properly. If it doesn't then we'll go from there.

I installed some libtiff stuff using the Synaptic Package Manager
but I get the same result.
What do I gotta do about libtiff?

Sorry for jumping in but I guess I know something about this. Ubuntu 7.04 use
libtiff4 which
is the only version available by Synaptics repo's. You need libtiff3 but might
be ok if you make a symlink
to libtiff4. I don't know if the libs are compatible but it's worth a try.

Curiouser and curiouser. I can't see why it would be looking for
libtiff.so.3. Previously, from running ldd, you got:
~$ ldd /usr/local/lib/libwxeu.so
...
libtiff.so.4 => /usr/lib/libtiff.so.4 (0xb6b27000)
...
So it shouldn't be needing that version. I think the v0.9 version of wxeu
would have linked to libtiff3, but the version I sent to you was also built
on Ubuntu 7.04, using the 'stock' wxWidgets libaries.
In any case, this dependency is generated in the wxWidgets libraries, not
wxEuphoria (which just depends upon those). In v0.9, IIRC, the wxWidgets code
was statically linked inside of libwxeu.so, and due to the specifics of the
box where it was built, some utility libraries (like libtiff) were meant to
come from the system, vs using the code supplied with wxWidgets (when
compiling wxWidgets, you have the option of using the system libs, or
using the ones they supply, which is what I should have done back then,
because it would have been more portable). Part of this learning curve
has been me getting more familiar with *nix and the GNU and wxWidgets
build system.
So, in summary: Can you run ldd against libwxeu.so again?

OK, this is clearly a different result than you got on 12 June. Based on
the names of the wxWidgets libraries, it looks like it's looking for the
ANSI versions of the libraries, not the Unicode version (which have a 'u'
in the fileanme after the gtk2), which is what gets installed through
Synaptic. Somehow, you're looking at the official released library, and
not the one that I later built to use the default Feisty libs
(http://wxeuphoria.sf.net/libwxeu.so.tar.gz).
If you do a search (from the web interface, just click on the subject above)
for this thread, and go down to your ldd output from 12 June, you'll see
that the names are different, and that it's looking for libtiff.so.4.
This version of the library must have been built with Ubuntu 6.10 (as
I believe the alpha and beta versions were)--also, you seemed to have the
beta version of wxeud.e, so I think this is a reasonable conclusion.
Make sure that the library is up to date (it should have been created on
11 June). It might be easier to just purge all wxEuphoria stuff and start
from scratch. Just make sure that you get the newer binary, *not* the
version that's on the download page.

I agree, looking at these results. Run:

Still didn't work.

Ok, let's try ld-linux.so.2 on that library to see what we get.

I suppose we need to figure out what that symbol is, and why it's not there.
I have no idea where that might be coming from. I haven't been able to
sit down with my linux box, so I haven't had a chance to track it down yet.
I'll try to take a look tonight.

How can we go about tracking down that symbol?
I did a Google search on it. No success.
Does the name _Z14NewStringConstPKc use Microsoft Hungarian notation?
Is it possible to figure out stuff about it from the name?

No, it's one of mine. I use some of the Euphoria backend to do stuff in
C++, which makes the Euphoria code simpler, since I create all of the C++
objects in C++. The stuff around the name is just g++ name mangling.
The catch was that the unicode version of some wxWidgets string handling
routines needed a "const * char" rather than a "* char" like Euphoria uses,
so I copied the NewString routine and changed it to return a const.
Somehow, it managed to build, and I managed to 'test' it by using the old
shared library (i.e., I didn't test it at all). I had a few minutes a
couple of days ago, and I found that out. I tried a clean build, and
realized that where I'd used literal strings in the code, I hadn't used
the wxWidgets-provided portable macro that converts your data to either
unicode or ansi, based on your compilation options.
So I still need to go through the code and fix all those places. I'll
really try to get that done in the next day or two. Seriously. I
really mean it this time....

OK, I think I've got it working now. Try:

Install it (either /usr/local/lib or /usr/lib) and run ldconfig on that

I can't figure out why it segfaults. But it still works when loaded by

Make sure you get a core file and try GDB? I'm not experienced at that kind of
thing but I know that it can be done.
You may have to turn core files on with "ulimit -c" and setting a value other
than zero.
http://www.unknownroad.com/rtfm/gdbtut/gdbadvanced.html#CORE
And other pages brought to you by Google.
Hope that helps!
