Well I don't have more than one version of Lua or wxWidgets installed. I
installed them directly form the apt repository in Ubuntu. I checked ldd and
did not find any .so that linked to anything outside the systems version of
Lua. Could it be a difference because wxLua is bound to 2.8.10 and the
version I am building is using 2.8.11?
I also tried using the local only versions and it still segmentation faults.
So I did find out that if I use 'wxlua' to run the scripts everything works
fine. So it seems to be erroring out using the wxLua Lua module (wx.so) from
strait lua. Does that help at all? In fact, it is not the line of requiring
that seg faults, it is the first time you call into the library and display
a GUI element (like a wxMessageBox). Now if I pass the wrong parameters to a
function in wxLua it will give me the normal wxLua error message. It does
not actually seg fault on that. Does this help?
