Building swift-3.1-branch from source

Development Compiler
1

Hi, I'm trying to build a toolchain from swift-3.1-branch on Linux.

I cloned GitHub - apple/swift: The Swift Programming Language 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
swift-3.1-branch".

Then I ran:

./swift/utils/build-script --preset=buildbot_linux
install_destdir=/home/ipartrid/swift-3.1
installable_package=/home/ipartrid/swift-3.1.tar.gz

But this fails with:

Traceback (most recent call last):
  File "./swift/utils/build-script", line 27, in <module>
    from SwiftBuildSupport import (
  File "/home/ipartrid/swift-source/swift/utils/SwiftBuildSupport.py",
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.

Many thanks,

You can use ./swift/utils/update-checkout --scheme swift-3.1-branch which will switch the branches to the right place for you. Some of the git repositories aren't necessarily the same; using the update-checkout script to select the right ones will be more successful. You can also use --reset-to-remote if you've made local changes that you want to throw away or want to ensure that it does the right thing from a clean update.

Thanks Alex, I wasn't aware of --scheme.

Unfortunately the same problem is present after using that though:

$ git clone GitHub - apple/swift: The Swift Programming Language # fine
$ ./swift/utils/update-checkout --clone # fine
$ ./swift/utils/update-checkout --scheme swift-3.1-branch # fine
$ ./swift/utils/build-script --preset=buildbot_linux
install_destdir=/home/ipartrid/swift-3.1

I had to remove swift/utils/swift_build_support/__init__.pyc if it is there
(it got generated when I use the checkout script from the master branch).
Wonder if that might help you.

What version of clang are you using? I’ve had the same problem with clang 3.9 when building on Ubuntu 16.04 on RasPi: https://twitter.com/ffried/status/833985445516165121
Using clang 3.8 worked fine.
