So, I have engine built from master branch this night and Vulkan SDK 1.0.30.0 installed.
And then I receive following error when I package my project:
UATHelper: Packaging (Android (ASTC)): UnrealBuildTool: C:\Users\A858\Documents\GitHub\UnrealEngine-master\Engine\Source\Runtime\VulkanRHI\Private/VulkanShaders.cpp:1708: error: undefined reference to 'GValidationCvar'
UATHelper: Packaging (Android (ASTC)): UnrealBuildTool: clang++.exe: error: linker command failed with exit code 1 (use -v to see invocation)
UATHelper: Packaging (Android (ASTC)): UnrealBuildTool: ERROR: UBT ERROR: Failed to produce item: C:\Users\A858\Documents\Unreal Projects\EVR_1 4.15\Binaries\Android\EVR_1-Android-Shipping-armv7-es2.so
