Re: Compile on x86, run on ARM?

[Asko Kauppi <askok@...>]

yes. :)

Which is weird since if you're having problems with x86 it's not the  
endian issue, then.

You might want to check the code actually giving that error; Lua  
source is fairly simple to grasp, unlike many other open source  
projects I've seen. Perhaps it's due to having only 3 major  
developers, who are quite feature cautious.
