Android build error on Mac 10.15.4

[xing-mei]

Pulled latest bx, bimg, bgfx. Ran make android-arm or make android-arm64 and failed with the following error message:

../../../src/renderer_vk.cpp:139:1: error: unknown type name 'PFN_vkSetDebugUtilsObjectNameEXT'
...
../../../src/renderer_vk.cpp:139:1: error: unknown type name 'PFN_vkSetDebugUtilsObjectTagEXT'
...

Seeme something wrong with vulkan related macros.

My android NDK is r16b. ANDROID_NDK_ROOT, ANDROID_NDK_ARM, ANDROID_NDK_MIPS. ANDROID_NDK_X86 has been set following https://bkaradzic.github.io/bgfx/build.html. Anyone ran into the same issue?

Thanks.

Sounds like it's not using the Vulkan headers coming with bgfx, those function pointers types are definitely defined in the bundled vulkan_core.h

If you have the Vulkan SDK installed, try renaming vulkan.h temporarily so it picks up the correct headers from bgfx/3rdparty.

@pezcode thanks . I do have a vulkan.h in ndk_dir/sysroot/usr/include/vulkan/. I renamed it and problem solved, but I can't leave ndk like that since I have multiple android projects going on. Any way to enforce the search path for bgfx android build?

[pezcode]

From a quick glance $(ANDROID_NDK_ROOT)/usr/include is added as an include path by bx and then transitively added to bgfx. I'm not familiar enough with the build system but @bkaradzic might have an idea on how to improve include path ordering here.

I'll probably change directory name in 3rdparty/khronos. vulkan -> vulkan1 or something like that.
