Here is a GLFW package compatible Windows and Linux.
No flag have to be set to make it compatible with your operating system.
Default POSIX/LINUX implementation use X11. If you want to use Wayland or Mesa instead use flag MESA or WAYLAND
UPDATE : The package present in this post is up to date (at least until UppHub have been released)
A simple example code :
#include <Core/Core.h>
#include <GLFW/glfw.h>
const unsigned int SCR_WIDTH = 800;
const unsigned int SCR_HEIGHT = 600;
CONSOLE_APP_MAIN{
// glfw: initialize and configure
glfwInit();
//Major and Minor stand (in this case) for OpenGL 3.2
//Make sure your OpenGL implemntation is compatible with the version exaplained here
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 2);
//If you OpenGL version is higher than 3.2 :
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
//else if it's below :
//glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_ANY_PROFILE);
#ifdef __APPLE__
glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
#endif
// glfw window creation
GLFWwindow* window = glfwCreateWindow(SCR_WIDTH, SCR_HEIGHT, "Ultimate++", NULL, NULL);
if (window == NULL)
{
Upp::Cout() << "Failed to create GLFW window\n";
glfwTerminate();
Upp::Exit(-1);
}
glfwMakeContextCurrent(window);
// Glew: load all OpenGL function pointers
glewExperimental=true;
if (glewInit() != GLEW_OK){
Upp::Cout() << "Failed to initialize GLEW\n";
Upp::Exit(-1);
}
//the game loop
glViewport(0,0, SCR_WIDTH, SCR_HEIGHT);
while (!glfwWindowShouldClose(window)){
glfwSwapBuffers(window);
glfwPollEvents();
}
glfwTerminate();
}
EDIT: at the moment LINUX version have been tested on X11. Some Memory leaks have been reported. (probably due to a AMD driver bug)
EDIT2: Cocoa (MacOS) and Wayland and Mesa have not been tested yet.

Hello Xemuth,
Nice work! I hope it will mature well.
I have tested it on ArchLinux (Setup:)
Linux 5.9.8,
GCC 10.2.0, x86_64
CLANG 11.0.0 x86_64,
Gnome 3.38, WAYLAND/xwayland,
GL_VERSION: 4.5 (Compatibility Profile) Mesa 20.2.2
GL_RENDERER: AMD OLAND (DRM 2.50.0, 5.9.8-arch1-1, LLVM 11.0.0)
GL_VENDOR: X.Org
IT compiled just fine. A blank window with "Ultimate++" title is created. And on exit, heap leaks are reported (as expected, I presume?)
Best regards,
Oblivion

Hello Xemuth,
I am glad it is working! I am also happy UppHub will have this awesome package for the premiere. Good job!
Also, please replace "int main()" with CONSOLE_APP_MAIN thanks to Core we are in U++ world
return -1 can be replaced with Upp::Exit(). Also, you could consider adding description to GLFW package - what it is. It is very helpful information when you don't know anything about package and wants to try.
I tested it on my machine with Radeon GPU on Manjaro (X11) and in the window I saw only blinking artifacts . This might be the library problem or something else. I will probably do not have time to dig more.
Small remark:
Upp::Cout() << "Failed to create GLFW window" << Upp::EOL;
Could be replace with
Upp::Cout() << "Failed to create GLFW window\n";
Oblivion the leak problem is related to leak in AMD drivers we (Mirek and I) fought with it in the past for GLCtrl but without success.

The quick example I provided was taken from web. I had change the original post to make it U++

Yes, the next update (which will include Wayland and Mesa) will have a description

The example I provided only open a Window, acquire an OpenGL context and loop infinlty. the window is supposed to be fully black. In your case it probably come from lib. do you have a dedicated GPU ? or is it an integrated one ? do you know your OpenGL version ? (if you have Mesa, you can type commande glxinfo, see OpenGL version string)

I have dig up an old machine and put Lubuntu in it (so I'm running X11) with an intel CPU (pentium 4 + integrated intel GPU) and leak still happen. Maybe I'm naive but my system dont have amd driver, so the problem is may be related to my lib.
@Oblivion how have you retrieve system information you provided on this post ? is it a simple command ? (have not found it on web )
