[antlr-interest] Re: error : 'CharScanner.hpp:114: undefined reference' ... ???

[rhalin]

checked on the config, and its finding it.  For reference, I 
installed antlr on a copy of slackware 9.0, it's only been up and 
running for a week, no preexisting version of antlr that I'm aware 
of, and no upgrades on the gcc or anything like that, went right from 
installing antlr to trying to compile my project, but no luck.  I'll 
keep poking around, see if I can come at something, thanks for the 
help!
