GLFW cannot create a window: "GLX: Failed to create context: GLXBadFBConfig" - c++

Question

I'm trying to create a glfw window in my Debian Stretch system.
The code for initialize glfw:
// Initialize GLFW
void initGLFW()
{
if (!glfwInit())
{
exit(EXIT_FAILURE);
}
glfwSetErrorCallback(errorCallback);
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 4);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 0);
glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_FALSE);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);
glfwWindowHint(GLFW_OPENGL_DEBUG_CONTEXT, GL_TRUE);
window = glfwCreateWindow(WINDOW_WIDTH, WINDOW_HEIGHT, "GLSL4.3 + GLM + VBO + VAO", NULL, NULL);
if (!window)
{
fprintf(stderr, "Failed to open GLFW window.\n");
glfwTerminate();
//system("pause");
exit(EXIT_FAILURE);
}
}
When I run the executable I get the messages above. Why?
GLX: Failed to create context: GLXBadFBConfig
Failed to open GLFW window.
Running with LIBGL_DEBUG=verbose I get this
libGL: Can't open configuration file /home/rafael/.drirc: No such file or directory.
libGL: pci id for fd 5: 8086:0a16, driver i965

The initGLFW function is the first function called from main.

You are trying to create an OpenGL 4.0 Core profile context:
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 4);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 0);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
Your driver/OpenGL implementation only supports up to 3.3:
OpenGL core profile version string: 3.3 (Core Profile) Mesa 11.2.2
Max core profile version: 3.3
Mesa 11.2.2 could support OpenGL 4.1 but only on certain drivers (from the release notes of 11.0.0):
OpenGL 4.1 on radeonsi, nvc0
Mesa 12.0.0 seems to support OpenGL 4.3 on i965:
OpenGL 4.3 on nvc0, radeonsi, i965 (Gen8+)
The fix would be to update your graphics card, Mesa3D or to create a 3.3 context instead:
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
