I have a fresh checkout and I'm suddenly seeing a bunch of configuration & build errors. This is on a mac (10.14.2, Xcode 10.0, Xcode 10.2 beta 3, cmake 3.13.4).
When configuring, it appears that LLVM_LIBRARY_DIR contains variables which don't get expanded.
CMake Error at stdlib/public/SwiftShims/CMakeLists.txt:106 (message):
Clang headers were not found in any of the following locations:
/(snip)/swift-sources/build/Xcode-DebugAssert/llvm-macosx-x86_64/$(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME)/lib/clang/7.0.0;/$(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME)/lib/clang/7.0.0;/Debug/lib/clang/7.0.0
Call Stack (most recent call first):
stdlib/public/SwiftShims/CMakeLists.txt:111 (find_llvm_clang_headers)
After editing the CMake file with the absolute path, configuration proceeds but building fails because it tries to output in to a bunch of '.swiftmodule' folders which apparently don't get created:
/swift-sources/build/Xcode-DebugAssert/swift-macosx-x86_64/Debug/lib/swift/macosx/SwiftPrivate.swiftmodule/x86_64.swiftinterface
(This goes for Swift.swiftmodule, SwiftOnoneSupport.swiftmodule, Darwin.swiftmodule, ObjectiveC.swiftmodule, etc. I started creating them, which allowed building to proceed, but there seem to be quite a lot of them).
Is anybody else seeing these kinds of issues, or is my configuration just borked in some way?
Thanks.
