I am trying to use both Bison and Flex in C++ mode so I can utilise features like vectors. I am using Visual Studio 2019 and the pre-compiled win_flex_bison3-latest.zip as found here to make my custom build rules (version 3.7.4).

I have attempted to enable C++ input by adding %require "3.7.4" and %language "c++" to the prologue. When I then try to rebuild my solution it results in some 109 errors.

Bison Input

%require "3.7.4"
%language "c++"
%define api.value.type variant

%{
#include <stdlib.h>
#include <stdio.h>
#include <vector>
extern "C" int yylex();
void yyerror(const char*);
extern int yy_flex_debug;
float *stmts;
void print(float *start, float *end);
%}

// Assign tokens to member of union
%token <ival> INTEGER
%token <fval> FLOAT
%type <fval> expr 
%type <std::vector<float>> stmt_list;
// Associativity
%left '-' '+'
%left '*' '/'

%%

// Formal grammar
program:	
			stmt_list '\n'			{
										for (std::vector<float>::iterator it = $1.begin; it != $1.end(); ++it){
											printf("Result: %g\n", *p);
										}
									}
			| program stmt_list '\n'	{
										for (std::vector<float>::iterator it = $2.begin; it != $2.end(); ++it) {
											printf("Result: %g\n", *p);
										}
									}
			;

stmt_list:
			expr ';'				{
										$$ = {$1};
									}
			| stmt_list expr ';'	{
										$$ = $1;
										$$.push_back($2);
									}
			| error ';'				{
										$$ = {};	// Empty vector
									}
			| stmt_list error ';'	{ $$ = $1; }	// Do nothing 
			;

/*stmt:
			expr ';'			{ $$ = $1; }
			| error ';'
			;
*/
expr:
			INTEGER		{ $$ = $1; }
			| FLOAT			{ $$ = $1; }
			| expr '-' expr	{ $$ = $1 - $3; }
			| expr '+' expr { $$ = $1 + $3; }
			| expr '*' expr { $$ = $1 * $3; }
			| expr '/' expr { $$ = $1 / $3; }
			| '(' expr ')'	{ $$ = $2; }
			;

%%

void yyerror(const char* msg){
	fprintf(stderr, "ERROR: %s\n", msg);
}

void print(float *start, float *end){
	for (float* p = start; p < end; p++) {
		printf("Result: %g\n", *p);
	}
}

int main(void){
	// Explicitly disable lex tracing
	yy_flex_debug = 1;
	yydebug = 0;
	yyparse();
	return 0;

I'm unsure if I'm doing something wrong or if this is a bug, I tried to follow the bison manual as closely as possible.

For the warnings see #29

The 1st error is that C++ flex source code requires FlexLexer.h to be available in include paths (add include path to FlexLexer.h or copy it to folder where C++ compiler can find it).
See #69 (comment)

1>C:\repos\Calculator\Calculator\calculator.flex.cpp(368,10): fatal error C1083: Cannot open include file: 'FlexLexer.h': No such file or directory
