***********************************

The above code is not complete. If i compile this file ( syn_yacc.y)

by "yacc" then it is compiling . But if i compile it

using "bison -y" then it is giving following error

 

syn_yaccL7.y:103: type clash (`' `ival') on default action
syn_yaccL7.y:104: type clash (`' `ival') on default action
syn_yaccL7.y:105: type clash (`' `ival') on default action
syn_yaccL7.y:106: type clash (`' `ival') on default action
syn_yaccL7.y:107: type clash (`' `ival') on default action
syn_yaccL7.y:108: type clash (`' `ival') on default action
syn_yaccL7.y:109: type clash (`' `ival') on default action
syn_yaccL7.y:275: symbol syntax is used, but is not defined as a token and has no rules

Note: Nowhere the "syntax" is used except the following positions shown

in the file

 

Can you give me the solution?????

 

thanks in advance
