Error when executing ./Glitter on debian #23

jokoon commented 8 years ago

Everything builds fine, I installed lXi6, and other package ending with -dev (I think it's the right thing, but I don't know which to install exactly).

I get

Failed to Create OpenGL Context

Polytonic commented 8 years ago
  1. What graphics card do you have?
  2. Have you installed your graphics card drivers?
  3. Is your graphics card OpenGL 4+ compatible?
jokoon commented 8 years ago

Intel HD Graphics 5500.

I installed debian 7, not sure if the graphic drivers were installed automatically, but I guess they did.

Don't tell me this is not compatible, this laptop is brand new.

And why should it be opengl 4+ compatible, opengl core is 3.3.

Polytonic commented 8 years ago

Glitter is configured for OpenGL 4.0 out of the box. If your card is not GL 4+ compatible, please change lines 16 and 17 in main.cpp to use OpenGL 3.3.

glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);

Some versions of the Linux Mesa driver are not GL 4 compatible if I remember correctly.

jokoon commented 8 years ago

I actually had the same problem with the learnopengl tutorials which uses 3.3.

I solved it by installing a backport driver. (jessie-backports, apt-get install -t jessie-backports)

Sorry to open such an issue for something which is unrelated.
