OpenGL renderer string: AMD Radeon Pro 555X OpenGL Engine OpenGL vendor string: ATI Technologies Inc. Opengl-app$ _GLX_VENDOR_LIBRARY_NAME=mesa MESA_LOADER_DRIVER_OVERRIDE=zink GALLIUM_DRIVER=zink build/glxinfo Users/dwiniecki/src/opengl-app/local_zink/lib/libGL.1.dylib (compatibility version 4.0.0, current version 4.0.0) I added those function calls near the end of glxinfo and this was the result: opengl-app$ otool -L build/glxinfo If the GL_RENDERER string says something like “… OpenGL Engine” then MESA is using the MacOS system version of OpenGL. Hmm.Ĭan you get the runtime to log the result of glGetString(GL_VERSION) and glGetString(GL_RENDERER)? That makes it look like zink should be used. usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1311.0.0) usr/local/opt/libx11/lib/libX11.6.dylib (compatibility version 11.0.0, current version 11.0.0) tmp/zink/lib/libGL.1.dylib (compatibility version 4.0.0, current version 4.0.0) MacOS has this otool command… It says: $ otool -L build/glxgears If zink was being used I think the OpenGL version would probably be 3 or higher, but it that reports GL_VERSION = 2.1 ATI-4.6.20. I was expecting the output from glxgears with the -info option to include “zink” somewhere, but it doesn’t, so I think this might not actually be using zink, vulkan, or metal. That gcc is whatever macOS provides by default (or maybe it was installed along with Xcode, I’m not sure).

I cloned:Īnd then an example of the meson commands I’ve tried (none of which work) is: meson -prefix=/tmp/zink -Dgallium-drivers=zink -Dmoltenvk-dir=~/src/opengl-app/MoltenVK/Package/Release/MoltenVK -Dc_std=c11 build-zink I’ve tried to build Zink but haven’t succeeded yet.
#Mac os opengl how to
I read that I may still be able to use OpenGL on macOS by running it on top of Zink from the Mesa project, on top of MoltenVK, on top of Apple’s Metal graphics API.īut I’m having trouble figuring out how to set up Zink, Mesa3D, MoltenVK, etc. I’ve read this is expected on newer versions of macOS.
Awhile ago I tried and got something to run but it seemed to be broken so I assume OpenGL doesn’t work on this version of macOS. I want to play with OpenGL on macOS 11.6.
