Hello, I have a problem with a sematic action when I use int_p. I have the following declaration: array_declaration = confix_p(LEFT_BRACKET, int_p[new_int] ,RIGHT_BRACKET); and new_int is defined in the following way: typedef function< void( int ) > Int_action; Int_action new_int ( bind( &SemanticActions::new_int, &self.actions_, _1 ) ); in this case I get allways (VS2005) the error message: Error 1 error C2064: term does not evaluate to a function taking 2 arguments C:\Programme\boost\boost_1_34_1\boost\spirit\core\scanner\scanner.hpp 146 if I use instead of the Int_action a action typedef function< void( const char*, const char* ) > Str_action; I have no errors during compiling. What I make wrong? Best regards Hansjörg
