Greetings everyone,Hi Pascal, All,
Btw, thanx alot for your help AND patience.
I have now constructed my min grammar file which goes like :
a = 'a';
b = 'b';
s = a s [second]:a |
I generated all my classes and I implemented them in a main class …
However when I try to run the program I obtain the following error
from the lexer.java class :
"The file \"lexer.dat\" is either missing or corrupted."
To make sure that the lexer.dat file is not missing I have put it in
C: and change the code to :
However I still obtain the same error msg (The error occurs as soon as
lexer tries to read the lexer.dat file in int length = s.readInt();
As always your help is really appreciated
As mentioned by the SableCC error message, i think that your problem is
related to corruption of the file lexer.dat.
You do not need to move this file.
What you can do is :
first, re-build SableCC(ant clean; ant jar).
then, generate the classes for your grammar by running SableCC. Before
that, make sure to remove old generated files if necessary.
I hope this can help you,
