exception handling / linkage problem: tolua, tolua++, and lua 5.1

["Thomas Breuel" <tmbdev@...>]

I'm trying to get tolua++ and lua 5.1 to work together with each other and with exception handling (it's for our open source OCRopus project, www.ocropus.org).

The problem is that when I compile lua 
5.1 with exception handling (by compiling it with g++), lua ends up using C++ linkage/name mangling.  Tolua++, on the other hand, always uses C linkage, even when compiled with C++. 

Tolua 5.1b seems to work the same way.

So, is there some way of getting an unpatched tolua(++) to work with an  unpatched lua 5.1 and exception handling?  Would it be possible to update tolua and/or lua so that unpatched versions install cleanly in /usr/local and support exception handling?

Thanks,
Thomas.
