ARSharedWorld fails to package at the build command for iOS with the following messages.
Packaging (iOS): [1/4] sh /Volumes/Storage/Workspaces/Release/Samples/AR/ARSharedWorld4.23/Binaries/IOS/ARSharedWorld Packaging (iOS): Undefined symbols for architecture arm64: Packaging (iOS): "_glDeleteFramebuffers", referenced from: Packaging (iOS): -[FIOSView DestroyFramebuffer] in Module.ApplicationCore.cpp.o Packaging (iOS): "_glDeleteRenderbuffers", referenced from: Packaging (iOS): -[FIOSView DestroyFramebuffer] in Module.ApplicationCore.cpp.o Packaging (iOS): "_glGenRenderbuffers", referenced from: Packaging (iOS): -[FIOSView CreateFramebuffer:] in Module.ApplicationCore.cpp.o Packaging (iOS): "_glBindRenderbuffer", referenced from: Packaging (iOS): -[FIOSView CreateFramebuffer:] in Module.ApplicationCore.cpp.o Packaging (iOS): -[FIOSView UpdateRenderWidth:andHeight:] in Module.ApplicationCore.cpp.o Packaging (iOS): "_glGetRenderbufferParameteriv", referenced from: Packaging (iOS): -[FIOSView CreateFramebuffer:] in Module.ApplicationCore.cpp.o Packaging (iOS): "_OBJC_CLASS_$_EAGLContext", referenced from: Packaging (iOS): objc-class-ref in Module.ApplicationCore.cpp.o Packaging (iOS): "_glGenFramebuffers", referenced from: Packaging (iOS): -[FIOSView CreateFramebuffer:] in Module.ApplicationCore.cpp.o Packaging (iOS): "_kEAGLDrawablePropertyRetainedBacking", referenced from: Packaging (iOS): -[FIOSView initInternal:] in Module.ApplicationCore.cpp.o Packaging (iOS): "_glFramebufferRenderbuffer", referenced from: Packaging (iOS): -[FIOSView CreateFramebuffer:] in Module.ApplicationCore.cpp.o Packaging (iOS): -[FIOSView UpdateRenderWidth:andHeight:] in Module.ApplicationCore.cpp.o Packaging (iOS): "_glGetError", referenced from: Packaging (iOS): -[FIOSView CreateFramebuffer:] in Module.ApplicationCore.cpp.o Packaging (iOS): -[FIOSView UpdateRenderWidth:andHeight:] in Module.ApplicationCore.cpp.o Packaging (iOS): "_glCheckFramebufferStatus", referenced from: Packaging (iOS): -[FIOSView CreateFramebuffer:] in Module.ApplicationCore.cpp.o Packaging (iOS): -[FIOSView UpdateRenderWidth:andHeight:] in Module.ApplicationCore.cpp.o Packaging (iOS): "_glBindFramebuffer", referenced from: Packaging (iOS): -[FIOSView CreateFramebuffer:] in Module.ApplicationCore.cpp.o Packaging (iOS): -[FIOSView UpdateRenderWidth:andHeight:] in Module.ApplicationCore.cpp.o Packaging (iOS): "_kEAGLColorFormatRGBA8", referenced from: Packaging (iOS): -[FIOSView initInternal:] in Module.ApplicationCore.cpp.o Packaging (iOS): "_kEAGLDrawablePropertyColorFormat", referenced from: Packaging (iOS): -[FIOSView initInternal:] in Module.ApplicationCore.cpp.o Packaging (iOS): ld: symbol(s) not found for architecture arm64
These messages are then followed by a generic clang error:
UATHelper: Packaging (iOS): clang: error: linker command failed with exit code 1 (use -v to see invocation) PackagingResults: Error: linker command failed with exit code 1 (use -v to see invocation) UATHelper: Packaging (iOS): Took 23.745284s to run mono, ExitCode=5
This issue did not occur in //UE4/Release-4.22.3 Live binary, so this appears to be a regression in 4.23.
Results: Package fails at the build command with a clang error
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-77520 in the post.
