c++ - Enabling OpenGL 4.1 under OS X 10.10 with GLEW, GLFW and g++ compilation -


i have 2014 rmbp, updated latest version of os x should guarantee me compatibility opengl 4.1. have put minimal working example:

#include <iostream>  #include "gl/glew.h" #include <glfw/glfw3.h>  using namespace std;  int main(){     int windowwidth = 800;     int windowheight = 800;     string windowtitle = "title";      glfwdefaultwindowhints();     glfwwindowhint(glfw_opengl_forward_compat, gl_true);     glfwwindowhint(glfw_opengl_profile, glfw_opengl_core_profile);     glfwwindowhint(glfw_context_version_major, 4);     glfwwindowhint(glfw_context_version_minor, 1);      if( !glfwinit() )     {         cerr << "failed initialize glfw.\n";         return 1;     } else {         clog << "initialized glfw." << endl;     }      glfwwindow* pwindow = glfwcreatewindow(windowwidth, windowheight, windowtitle.c_str(), 0, null);      glfwsetwindowpos(pwindow, 700, 200);     glfwmakecontextcurrent(pwindow);     if( pwindow == null )     {         cerr << "failed open glfw window.\n";         glfwterminate();         return 1;     }      std::cout << "gl version: " << glgetstring(gl_version) << "\n";     std::cout << "glsl version: " << glgetstring(gl_shading_language_version) << "\n";     std::cout << "vendor: " << glgetstring(gl_vendor) << std::endl;     std::cout << "renderer: " << glgetstring(gl_renderer) << std::endl;      while (!glfwwindowshouldclose(pwindow))     {         glfwpollevents();     }     glfwdestroywindow(pwindow);     return 0; }

this opens window works fine, it's outputting following: gl version: 2.1 intel-10.0.86 glsl version: 1.20 vendor: intel inc. renderer: intel iris opengl engine

which wrong! should getting 4.1 compatibility. downloaded examples @ https://github.com/tomdalling/opengl-series , under xcode, go 4.1 know computer capable of it.

this larger project; did try importing project xcode, merging tom dalling's project, won't work, gl 2.1.

i'm compiling above code 

g++ main.cpp -o gltest -lglfw -framework cocoa -framework opengl -framework iokit -framework corevideo \

... maybe i'm missing option. thank help!

reading window creation hints at glfw site, you'll find:

these hints set default values each time library initialized glfwinit

and tom dalling's (working) code calls glfwinit before hinting version while yours afterwards.

so suspect may have it.
