Hi everybody,
I have a problem with my parser. I spent some hours trying to fix it, but I still don't understand what happens: My parser is uses lex to read strings and bison to work on them. The bison-file parser.y is like that: #define YYSTYPE char * The lex file is supposed to read strings and write them to yylval. First, I include the header, which I think should tell the scanner that yylval is a char-pointer #include "parser.h" Then I try to use it: yylval = strdup(yytext) The compiler (gcc) states that yylval is an integer: Warning: assignment makes integer from pointer without a cast My next thougth was that yylval is integer by default, and I added (which I found in a tutorial): Extern char *yylval Now, the compiler answers: Conflicting types for 'yylval' Previous declaration of 'yylval' Maybe somebody knows (or sees) what happens, Kind regards, Martin Bock _______________________________________________ help-bison@gnu.org http://lists.gnu.org/mailman/listinfo/help-bison
