I have had no difficulty with vxWorks 5.5 running Lua 5.1. However, I
don't know anything about this VxLuaGlue thingie; I just built the
standard distribution using the vxWorks compiler. There were two Lua
headers I had to add <vxworks.h> to, but made no other changes.

I have done both console I/O with io.read() and file I/O using
file:read(). However, on those occasions in which I wanted to do
raw console I/O, I used some of my own routines instead of io.read().

Of course, now that I've spoken up, I'm out the door for a week of
vacation, so I won't see any replies for a while...
