[chuck-users] 1.2.0.3 compilation problem

That is great to hear.  Switching to callback mechanism as default in 
1.2.0.1 seems to greatly help real-time stability across the board.

The requirements haven't (intentionally) changed since 1.2.0.1.  These 
compilations errors seem to be related to the new blocking commenting 
function.  After a quick google search, it looks like the error may be 
caused by inconsistent support of unput() macro in various portions of 
the lex file under linux.  So let's try:

1. download and replace chuck.lex and rebuild:

     http://chuck.cs.princeton.edu/release/files/snapshot/

did the error go away?

2. if not, try upgrading flex on your system and rebuild

if neither of the above works, then we shall look for another solution.

Best,
Ge!
