I don't have a Mac right now, are you saying that you have both gcc and
clang installed? That's what it seems like from the email with the compiler
logs, but now you say they're the same, but maybe with different default
flags? Or do you just mean that they're the same in that they both don't
work.

wxLua doesn't use anything in c++11, the errors you get are for other
things.
This is a hack to get at the base class in a simple and quick way, maybe an
easy fix.

Can you try compiling with this change? If it works I can commit the
changes to SVN.
static int wxluabaseclass_vtable_offsets_wxSimpleHtmlListBox[] = {
int(((long
int)(wxHtmlWindowInterface*)(wxSimpleHtmlListBox*)&wxluatype_TNONE) -
((long int)(wxSimpleHtmlListBox*)&wxluatype_TNONE)) };

What compiler is this one? GCC?
This means that wxWidgets doesn't have the body of this function linked in.
Strange, what does running 'nm -a wx-XXX.dylib | grep
GetHTMLBackgroundColour' on the wxWidgets libs say? I'm picking this
function since it's non-templated, but you can try it on any of them.
"non-virtual thunk to wxHtmlWindow::GetHTMLBackgroundColour() const",
referenced from:
vtable for wxLuaHtmlWindow in wxhtml_wxlhtml.cpp.o

I'm tempted to say that maybe the problem is that you're not linking to the
wxhtml lib. In CMakeCache.txt, does wxWidgets_COMPONENTS have "html" in the
list? You can also see the full linker command by looking at the "link.txt"
files in the cmake build dir you made.
This is an old thread, but maybe that's the problem.

You can change the wxLua optimizations easily by editing CMakeCache.txt in
the build dir and changing CMAKE_CXX_FLAGS_RELEASE (or whatever your build
is) to -O? to match what wxWidgets used. Then just rerun 'cmake
../path/to/wxLua', then make clean, and make again. If this works... I
don't know how we'd automatically figure out how to use the same
-----------------------------------
By the way, you might want to use the wxLua SVN trunk as it has some
updates and is very stable.
