Hi, I’m using GLFW for a small 3D app, which worked like a charm under Windows. I’m currently trying to make it work on an Arch Linux setup, which uses Gnome on Wayland.
As far as GLFW is concerned this is the code I use to create a window:
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3); glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 0); GLFWwindow* window = glfwCreateWindow(1280, 720, "Test", NULL, NULL);
I tested my code with both the
glfw-wayland (3.3.2) package on the Arch repo, and version 3.4.0 of GLFW fetched directly from GitHub and compiled with Wayland flags.
In both cases, when I build and run my code, a black surface of the requested size surrounded by a white-greyish border appears on my screen, but it’s not a window. It’s got no controls, it’s not grabbable, and my error callback also prints an error message which is different depending on the GLFW being used.
When using the Arch package (3.3.2), I get the following:
GLFW error: 0x10008, "Wayland: Focusing a window requires user interaction"
But when I use the GitHub version (3.4.0), I get this:
GLFW error: 0x1000c, "Wayland: The platform does not support setting the input focus"
Am I missing some steps that would be essential to Wayland, or is the Wayland part of GLFW still not to the point it can display windows?
Using an OpenGL 3.0 context was also the only way I got as far as I did. As per
glxinfo, I should be able to open an OpenGL 4.2 core context:
deqyra@Arch:/ $ glxinfo | grep version server glx version string: 1.4 client glx version string: 1.4 GLX version: 1.4 Max core profile version: 4.2 Max compat profile version: 3.0 Max GLES1 profile version: 1.1 Max GLES profile version: 3.0 OpenGL core profile version string: 4.2 (Core Profile) Mesa 20.0.7 OpenGL core profile shading language version string: 4.20 OpenGL version string: 3.0 Mesa 20.0.7 OpenGL shading language version string: 1.30 OpenGL ES profile version string: OpenGL ES 3.0 Mesa 20.0.7 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00
However, using the following calls:
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 4); glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 2); glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE); GLFWwindow* window = glfwCreateWindow(1280, 720, "Test", NULL, NULL);
I get the following error:
GLFW error: 0x10007, "EGL: Failed to create context: Arguments are inconsistent"
The same happened for all OpenGL core contexts between versions 3.2 and 4.2. I know that whenever Wayland is detected, an EGL context is automatically created no matter which hints are provided, but does it make it impossible to open an OpenGL core context?
Thanks in advance.
