I can try. Unfortunately this means that we would be deviating from
a normal Lua static library, which Debian will not appreciate.
Why should Debian not appreciate Enigma using C++ exceptions in Lua on
Windows compilations?
If the changes limit to the header includes like
extern "C" {
#include "lualib.h"
#include "tolua++.h"
}
we should be able to limit the Lua C++ compilation to Windows/MinGW.
Well of course, there is more to it then that.
First of all Such a change is difficult to limit to MinGW.
I have a basic patch. It comments out the 'extern "C"' c lines,
and explicitly compiles the lib-src/lua directory as C++ code.
I had to disable building tools, as tolua++'s executable
would not compile cleanly as c++. And it would not link cleanly to
a C++ liblua.
Even with these changes I'm still getting linking errors. But it is likely a
trivial problem
as it seems to be all calls to liblua code that are causing this.
I'll play with it some more and see if I can get it working.
I can certainly work on this patch. Are you aware of any catch-alls that
might be
in the unwind path of a lua exception?
luaconf.h:
/* C++ exceptions */
#define LUAI_THROW(L,c) throw(c)
#define LUAI_TRY(L,c,a) try { a } catch(...) \
{ if ((c)->status == 0) (c)->status = -1; }
#define luai_jmpbuf int /* dummy variable */
Oh... Yikes. I was aksing about Enigma accidentally cathing lua's exceptions
in a catch all.
This looks like Lua may end up accidentally catching enigma's exceptions.
That line would definately need to be edited.
