Hi there,
CVS was up, so I was able to try the very latest wxLua version.
strange: I still get errors when trying to access it - maybe only
developer CVS is down ? John, are you able to access it ?
So
far, I have just created a very simple C++application that links to
wxLua and runs a script that creates an user interface (I just grabbed
the script at wxLua's front page).
I have just took a very quick look at the examples that come with
wxLua, but it seems that the one I created is simpler than those, so
it may be useful for other beginners, too. I've uploaded it to
http://cscience.org/~lmb/MinimalEmbeddedWXLuaApp.zip. If the current
distribution really lacks an example as simple as this one, please
feel free to review and add this one to the distribution or to the
wxLua page.
Up to this moment, I have only five notes:
1. My wxWidgets installation doesn't include wxSTC, and I had to
manually pass the '--disable-wxbindstc' flag to the 'configure'
script. It would be nice if 'configure' could test for 'wxSTC'
presence and disable it automatically if it isn't found.
configure already tests for wxSTC... didn't you get a message 'wxSTC
could not be found etc etc' ?
It does not disable it automatically if not found for choice: wxSTC is
required for both wxLuaApp and wxLuaEdit applications... if you don't
have wxSTC then you miss two nice apps ;)
2. The file 'wxluasetup.h' was not installed by 'make install'. I had
to copy manually.
this is sure a big problem - thanks for reporting it.
Fixed in CVS (wxluasetup.h was erroneously installed into
$PREFIX/src/wxbind/setup instead of $PREFIX/include/wxbind/setup)
3. I think that the 'include' directory in '#include
<wxbind/include/wxbind.h>' is a bit cumbersome (I would prefer just
something like '#include <wxbind/wxbind.h>', for example). I can live
with this, though. :-)
this was not to pollute the compiler line with a lot of include paths
(we would need one for each subfolder in modules\ ...).
4. I had to link with 'wxlua_gtk2_wxluasocket-2.6', even though I
don't use sockets. Otherwise, I get some linking errors concerning
names that I would expect to find at 'wxlua_gtk2_wxluadebug-2.6'
instead:

5. Calling the Lua 'print()' function from a script run using
'wxLuaState::RunFile()' doesn't print anything at the terminal. Is
this being redirected to somewhere?
these last two are meat for John, I think ;)
I'll now start to try doing some real work with wxLua. So far it looks great!
Regards and congratulations for the work,
Thanks!
