i wrote my own main.cpp file
in order to compile and link it with
all my antlr project:

#include
#include "l.hpp"
#include "p.hpp"

void main ()
{

using namespace std;
basic_istream x();
L lexer(x);

P parser(lexer);
parser.startRule();
}


however this code doesn't compile well:
C:antlrantlr-2.7.1libcppsrcmain.cpp(13) : error C2664: '__thiscall L::L(class std::basic_istream > &)' : cannot convert parameter 1 from 'class std::basic_istream > (void)'
to 'class std::basic_istream > &'
Context does not allow for disambiguation of overloaded function

what is wrong with this code?
how can it be fixed?
can you supply a diferent and mybe better example as you did with the main.java?
please, i need an answer urgently
i would appreciate it very much if you
answer.
sincerely
