One of my goals is to give a better choice of binaries.  And you're right,
there should be some additional information.  I'll work on that.  If anyone
has recompiled on some distro, I'd be happy to put it up on the site.

In the mean time, I believe the immediate thing to try would be to run

 $ ldd /usr/lib/wxeu.so

That should identify the problem.  On some systems, adding a symlink for
an older library might work, though it's not really the best solution.

I had the same problem, on Fedora Core 5 (could not be opened) when i tried to
run the bench_draw.exw demo and some other programs. I tried the latest wxeu.so,
and it starts to load, but then i get the error:

   /home/ryanj/euphoria/include/wxEuphoria.e:1028 
   A machine-level exception occurred during execution of this statement

which is the line:

wxPRINT_POSTSCRIPT = peek4s( define_c_var( wxWin,
   "wxPRINT_POSTSCRIPT" )),

So, if i comment out that line, it gets stuck at the next statement:

   /home/ryanj/euphoria/include/wxEuphoria.e:1031
   A machine-level exception occurred during execution of this statement

Which is:

wxPRINT_WINDOWS = peek4s( define_c_var( wxWin, "wxPRINT_WINDOWS"
   )),

If i comment out that line too, it makes it as far as wxMain(), but still
crashes:

   /home/ryanj/euphoria/include/cplusplus.e:12 in procedure call_func()
   A machine-level exception occurred during execution of this statement

... called from /home/ryanj/euphoria/include/cplusplus.e:38 in function
   call_member()

... called from /home/ryanj/euphoria/include/wxEuphoria.e:8750 in procedure
   wxMain()

   ... called from ./bench_draw.exw:168

--> See ex.err

I also noticed it flash something just before crashing:

Gtk-WARNING **: libgdk_pixbuf.so.2: cannot open shared object file: No such
   file or directory

I don't know what's going on there...any ideas?

Fedora, Ubuntu, Red Hat, oh my!

Stop using some flavor of Linux that is ultimately going to be incompatible
with other Linuxes and get a real OS: FreeBSD.
