Problem with using cxx generator for SableCC

[Tabiul Mahmood]

I am trying to play around with SableCC and was using the indrek alternative output package to generate c++ output. For the grammar, I simply copied and pasted the grammar from this site http://improve.dk/writing-a-calculator-in-csharp-using-sablecc/

This is my shell script to make the project

find ./ -name "*.o" | xargs rm -f
java -jar sablecc-3-beta.3.altgen.20041114/lib/sablecc.jar -d src -t cxx grammar/simplecalc.sablecc
g++ -Isrc/SimpleCalc -c src/list.cpp src/node.cpp src/typeinfo.cpp src/analysis.cpp src/lexer.cpp src/parser.cpp src/main.cpp

This is main.cpp

#include<iostream>
#include<string>
#include "lexer.h"
#include "node.h"
#include "parser.h"
using namespace SimpleCalc;
int main(){
 return 0;

}

Upon running the shell script I am getting the below error

In file included from src/main.cpp:10:0:
src/SimpleCalc/lexer.h:63:11: error: ‘Token’ does not name a type

These are the files that are generated

• src/analysis.cpp  
  
• src/lexer.cpp  
  
• src/list.cpp  
  
• src/node.cpp  
  
• src/parser.cpp  
  
• src/SimpleCalc  
  
• src/typeinfo.cpp
  
• src/SimpleCalc/analysis.h  
  
• src/SimpleCalc/lexer.h

• src/SimpleCalc/node.h  
  
• src/SimpleCalc/parser.h  
  
• src/SimpleCalc/prod.h  
  
• src/SimpleCalc/token.h
  

The file main.cpp is located in the src folder

I am not sure what I am doing wrong. Appreciate if anybody could guide me

I have managed to fix the issue. Below should be sequence of include in the main.cpp

#include "node.h"
#include "token.h"
#include "lexer.h"
#include "prod.h"
#include "parser.h"
