I'm trying to run the example on: http://jflex.de/manual.html#Example I've copied the example and only changed the file/class name.
Running jflex seems to work fine.
$ jflex -v -d output/ grammer/scanner.flex
Reading "grammer/scanner.flex"
Constructing NFA : 148 states in NFA
Converting NFA to DFA :
.........................................
45 states before minimization, 26 states in minimized DFA
As a next step I try to compile the output. No matter what I do, I get these errors.
$ javac -cp .*:dependancies/java-cup-11b.jar output/scanner.java
output/scanner.java:788: error: cannot find symbol

I'm I forgetting something?
