I have no problem with this sample in MSW and Mandriva Linux. What
wxLua are you using, did you compile it yourself? What wxWidgets
version and from where? What Lua version and are you sure you're
compiling wxLua using the lua-devel package from Debian sid or are you
compiling wxLua with it's own Lua (in modules/lua) and then running it
with the system installed Lua?
The fact that the wxBitmapComboBox is created and does show if not
added to the sizer, but crashes when added to the sizer makes me think
that you have mismatched libraries. You can get very strange and
nearly undebuggable errors in these cases. Try running ldd on the
wxLua libs to make sure that the libs it links to are appropriate,
especially liblua.so being in /lib/, /usr/lib/, or somewhere like that
to confirm that you're using the system Lua.
Hope this helps,
John
