Mac Mojave + opengl

Question

Mac OS 10.14 Mojave was just released, and since June, we've known that OpenGL was to be deprecated in the OS. "OpenGL applications will continue to run, but you should switch to Metal," to paraphrase. However, there doesn't seem to be any documentation indicating whether you can still compile with OpenGL or if Apple prevents that or omits the proper development libraries. I am currently developing an OpenGL-based graphics program and cannot risk updating if compilation will no longer work. Has anyone tested this?

EDIT: Does anyone else share Esenthel's experience?

Answer 1

I can compile, however after updating to latest Mojave and Xcode, my OpenGL applications simply don't work.

In one case I get a hang during a system GL call, in another case just a black screen. And some errors in the output same as here: https://stackoverflow.com/questions/52507950/unable-to-load-info-plist-error-xcode-10-under-macos-10-14-mojave#=

I recommend that you don't update.

I think there's something broken in Xcode 10 OpenGL libraries.

Edit: It appears that later Mac OS and Xcode updates have fixed the problems.

Answer 2

GLFW work around. Similar to other answers, but you do not need to resize your window in the draw loop, just call glfwPollEvents() first.

window = glfwCreateWindow(width-1, height, "Hello World", NULL, NULL);
glfwPollEvents();
glfwSetWindowSize(window, width, height);

Also, glfwHideWindow() then glfwShowWindow() seems to work. Similarly glfwSetWindowPos() is an alternative. Though setting the window size seems faster than hide/showing the window, and I don't want to move the window position.
