Hi, I'm trying to build a toolchain from swift-3.1-branch on Linux.
I cloned https://github.com/apple/swift and ran
"./swift/utils/update-checkout --clone" successfully.
Then, for each subdirectory (swift, swift-corelibs-foundation, lldb,
llvm etc.) I switched to swift-3.1-branch via "git checkout
Then I ran:
But this fails with:
Traceback (most recent call last):
File "./swift/utils/build-script", line 27, in <module>
from SwiftBuildSupport import (
line 26, in <module>
from swift_build_support import diagnostics # noqa (E402)
ImportError: cannot import name diagnostics
Can anyone advise on how to build swift-3.1-branch? I'm pretty sure
my procedure above used to work, until recently.
