macOS: glfwGetRequiredInstanceExtensions failed

[niklaut]

I'm following the install instruction on macOS 13.6 on an ARM64 MBA M2. I installed the Homebrew and Vulkan SDK successfully. Cloned the scopehal-apps and set the exports correctly (also verified the paths).

cmake ../ -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_PREFIX_PATH="/opt/homebrew;/opt/homebrew/opt/libomp"
make -j12

experiences multiple errors during build:

But it does produce a ngscopeclient binary, which then fails with the same error.

$ ./src/ngscopeclient/ngscopeclient
    ERROR: glfwGetRequiredInstanceExtensions failed

I tried googling this error, but my complete lack of graphics understanding (I work on microcontrollers) makes this difficult to fix. For example: I tried export VK_ICD_FILENAMES=$VULKAN_SDK/etc/vulkan/icd.d/MoltenVK_icd.json from here, but that did nothing.

Is this because of my own config? Maybe a conflicting homebrew install?

[azonenberg]

The errors during build are due to a long-standing (but low priority) bug in which some unit tests try to initialize Vulkan during compilation during what's supposed to just be a pass to enumerate what test cases are available. But for some reason this init (which normally just wastes a bit of time) is failing.

The failure with ngscopeclient and the tests is the same, MoltenVK isn't initializing right. Try running ngscopeclient with --debug to dump more information that might help us narrow down the problem.

Hm ok, interesting. If I check the "System Global Installation" checkbox in the Vulkan SDK installer and then not export any paths, the build succeeds. Or maybe the reboot fixed it? Well… it's running now, thank you!
