However I cannot compile the Lexer.java file without the error: package java_cup.runtime does not exist I don't understand what the problem is, as I followed a tutorial which said that as long as the java-cup-11a.jar file is in the root folder then there shouldn't be any classpath problems. I have spent hours trying to fix this and would appreciate any help. jflex share|improve this question asked Mar 8 '13 at 16:02 user2149056 62 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote I suspect you have just copied a jflex file as the basis for your tutorial experiement and it has a %cup directive near the top. This directive instructs JFlex to generate java code to link the lexer to a CUP generated parser, and you aren't providing the expected CUP jar files to the java compiler. If you are producing a standalone scanner (which, if you are just starting a tutorial, you probably should be), you need to use the %standalone directive instead. share|improve this answer answered Mar 11 '13 at 4:47 Recurse 2,5171325 add a comment| up vote 0 down vote import java_cup.runtime.*; Just put that at the top of your .jflex file share|improve this answer answered Mar 11 '14 at 18:15 Oscar Robinson 302214 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

Join them; it only takes a minute: Sign up JFlex with CUP compile errors up vote 1 down vote favorite I am trying to run an example provided by CUP: Parsing directly to XML. I stored the 'Minijava http://stackoverflow.com/questions/36731648/jflex-with-cup-compile-errors Grammar' in a file named minijava.cup and the scanner into a file named xml.flex. I ran JFlex to obtain Lexer.java from the xml.flex file. After that I obtained Parser.java and sym.java after running the command specified on the CUP example: java -jar java-cup-11b.jar -locations -interface -parser Parser -xmlactions minijava.cup My directory looks like this: input.xml java-cup-11b.jar java-cup-11b-runtime.jar jflex-1.6.1.jar Lexer.java minyjava.cup Parser.java sym.java xml.flex I am trying to compile the Lexer.java file by using the following command: javac -cp java-cup-11b-runtime.jar Lexer.java but I get 47 errrors in the format "..cannot find symbol...". The first ones specify that classes sym and minijava.Constants can't be found. Lexer.java:17: error: cannot find symbol public class Lexer implements java_cup.runtime.Scanner, sym, minijava.Constants{ ^ symbol: class sym Lexer.java:17: error: package minijava does not exist public class Lexer implements java_cup.runtime.Scanner, sym, minijava.Constants { ^ Lexer.java:679: error: cannot find symbol {return symbolFactory.newSymbol("EOF", EOF, new Location(yyline+ 1,yycolumn+1,yychar), new Location(yyline+1,yycolumn+1,yychar+1));
