Make problem

[Alexis Vanacker]

Hello,

We are having problems when trying to "make" our grammar (with
java1.5). After running bnfc -m java1.5 CPP.cf, we run make, but the
Yylex.java file is empty! So the Test.java (or the lab4.java) file
cannot use it. Is there a way to fix this? What are the probable
causes?

There is a workaround which is to remove all the files previously created. Or maybe just remove the old Yylex.java file. And maybe make vclean does it.

We had tried this actually and it doesn't work... Thanks anyway.

I think I had the same problem. Try removing any "" (empty tokens) in
the grammar...
