    replied to flex and C++
    in C
    The problem was that C++ needed a FlexLexer object, and then execute the yylex() function through it.

    Like this:
    Code:
    int main() {
        FlexLexer* lexer = new yyFlexLexer();
        while (lexer->yylex() != 0)
                ;
        return 0;
}

    Solved, thanks.

      flex and C++

      I was trying to get a simple program to work with flex and C++. I can't figure out what's wrong though. With C it works, and I can execute yyflex() with no problems and the analyzer gets executed. With C++ on the other hand...
      Take a look:

      Code
      Code:
      %option noyywrap yylineno c++
%{
        #include <iostream>
%}
%%
"<"[A-Za-z]*">" { std::cout << YYText();
      ...
