glbinding sfml version

Use c++ glbinding to initialize and query opengl version.

glbinding leverages C++11 features like enum classes, lambdas, and variadic templates, instead of relying on macros; all OpenGL symbols are real functions and variables. It provides type-safe parameters, per-feature API headers, lazy function resolution, multi-context and multi-thread support, global and local function callbacks, meta information about the generated OpenGL binding and the OpenGL runtime, as well as tools and examples for quick-starting your projects. Based on the OpenGL API specification (gl.xml) glbinding is generated using scripts and templates that can be easily adapted to fit custom needs.

cpp

cpp/c++ 

const glbinding::Version version = glbinding::aux::ContextInfo::version();

example 

#include <SFML/Window.hpp>
#include <glbinding-aux/ContextInfo.h>	// glbinding::aux::ContextInfo
#include <glbinding/glbinding.h>	// glbinding::initialize
#include <glbinding/getProcAddress.h>	// glbinding::getProcAddress
#include <iostream>
#include <glbinding/Version.h>	// glbinding::Version
#include <string>
#include <memory>

using std::string_literals::operator""s;

int main(int argc, char * argv[])
{
	std::unique_ptr<sf::Window> win_uniq;
	if (argc == 2 && "true"s == argv[1])
		win_uniq = std::make_unique<sf::Window>(sf::VideoMode{2560, 1440, 32}, "SFML Window");

	glbinding::initialize(glbinding::getProcAddress, false);
	const glbinding::Version version = glbinding::aux::ContextInfo::version();
	std::cout
		<< "Version: " << version.toString() << '\n'
		<< (int)version.majorVersion() << ' '
		<< (int)version.minorVersion() << ' '
		<< std::endl
		<< std::endl
	;
	std::cout << std::boolalpha
		<< (version >= glbinding::Version{4, 6}) << ' '
		<< (version.majorVersion() >= 4) << ' '
		<< (version.minorVersion() >= 6) << ' '
		<< std::endl << std::endl;
}
