If I remember correctly the problem is that the build files DO specify

How do I tell if this is the case? I  have built the wxGL library, so I
don't know. I have also defined #define wxUSE_GLCANVAS       1 in "setup.h".
I have not touched any files in the wxLua source archive. I have set the
environment variable WXWIN to my wxWidgets install root directory. Am I
missing anything else?

If this is the case then

I am trying to determine how I am going to maintain this issue. If I edit
the files in wxLua, that means I can't external to the sources, once you
move to using SVN. Plus I don't want to maintain this for the lifetime of my
project.

Can you tell me what the bare minimum things are to use wxLua in my
application? Can you tell me what the bare minimum things required for using
wxLua as a Lua module? I think it starts to get into this in the
installation document, but I am still trying to build the entire package,
because usually makefiles are easy to build from.

<A personal sidebar discussion> (These are only thoughts not criticisms)
I am just asking, is BakeFile the way that you prefer to build wxLua. If
not, is the person that set them up going to return? I started using
BakeFile a couple of years ago and found it extremely complicated. So much
so that I can't even attempt to fix these issues I am having, in the place
where I believe the problem comes from, the BakeFiles. I do not mean any
disrespect and only ask to see if I can help figure out a bulletproof way of
building wxLua. It is so crucial for a package such as wxLua to be easy to
build because it is going to have the ability to be embedded in a users
application.
Your thoughts and remarks?
