Re: Using Lua in a C(++) program

[Asko Kauppi <asko.kauppi@...>]

I'm not sure your c++ problem is based on Lua.
The line you reported earlier:

	/tmp/ccV9wgqi.o(.eh_frame+0x11): undefined reference to 
`__gxx_personality_v0'

comes from mingw32/gcc when it tries to compile stuff as c++ but 
doesn't find the necessary runtime libraries when linking it.. I faced 
this when my source had CAPITAL names (unintentional though it was). 
The .C suffix confuses mingw to think it's c++.

So first thing:
- Make sure all your C files are *.c and all -real- c++ files *.cpp. 
NEVER use capital c. :)

If that's not the cure:
- Lua itself should compile either as c, or c++ (there really is some 
difference, under the hood). So i don't think it's that.

- If you're still missing the c++ runtime libs, there's probably some 
link flag or something you need to set. Look with 
"__gxx_personality_v0" via Google, perhaps?

Yours,
