Build fails for 3.1.1


(Carl Peto) #1

Hi all, I wonder if anyone can help? I'm trying to build Swift 3.1.1 from source code on a Mac and getting errors.

I've tried it with Xcode 9, Xcode 8.3.3, Xcode 8.2.1 and the latest attempt was with Xcode 7.2.1.

(In each case, I moved all other Xcode versions aside in the Applications folder and put the appropriate Xcode there instead.)

I checked out tag swift-3.1.1-RELEASE in a folder called swift in my test area then used the update-checkout as follows to check out related projects and dependencies:

utils/update-checkout --clone --tag swift-3.1.1-RELEASE

Finally, I used the build script as so:

utils/build-script -R --clean

I think it's capable of building swift/swiftc itself but is failing to build the standard library.

Here are the build errors when building with Xcode 7.2.1...

(see the bottom of the post for the build errors with Xcode 8)

...I can't easily change mac OS version (I'm on macOS 10.12.6) apart from upgrading to High Sierra or Mojave beta, but it sounds like that's not the issue anyway?

Can anyone help?

Summary


It looks like the Swift source code for 3.1.1 is probably supposed to be built against some version of Xcode 8 but the versions I've tried are not working.

Can anyone shed any light?


(Jordan Rose) #2

Hi, Carl. Swapping out your Xcode.app doesn't automatically change the configuration Swift is using to build—maybe it should, but it currently just uses what it has cached. Try utils/build-script -R --clean --reconfigure.

I believe Swift 3.1 should go with Xcode 8.3 and its associated SDKs.


(Carl Peto) #3

Thank you very much for your reply, that sounds good. Does anyone know which version of 8.3? There are four options, 8.3, 8.3.1, 8.3.2 and 8.3.3 (which is the one I tried and will now try again!)


(Jordan Rose) #4

Ah, the newest one should be fine.


(Carl Peto) #5

Cool. Trying your suggestion now, using Xcode 8.3.3. Crossing fingers. Cautiously optimistic. :) (p.s. I've been trying to compile this since WWDC but I'm finally on holiday so actually have a decent amount of time to spend on the problem while not exhausted working for da man!)


(Carl Peto) #6

OK I think it might have worked?

Dumb question, but does this look right?? These are the last messages printed out before it returned to the command line.

[1170/1170] Running utility command for swift-benchmark-macosx-x86_64

That's all!

I was sort of expecting to see a "completed" message and I wasn't expecting so many warnings!

But I don't see an "error" or "failed" message so I guess it's worked? (Running a quick compile of a super simple swift file seems to compile to sensible LLVM IR and on to roughly sane looking assembly language.)


(Carl Peto) #7

Answering my own question here...

The "fix" is once it looked like compilation was working, I ran again with tests enabled and got (nearly) a full pass... (I think the only failing test was because I've got some misconfiguration of my shell due to old programs in the PATH variable, I corrected that and it seems to have worked).

So here is my "definitive (ish) guide" to compiling swift 3.1.1 on your random macOS box.

  1. Create a directory to house all the source code. In my case it was simply /Code/swift. You might find ~/Documents/Code/swift or something similar easier and more normal.

  2. Go into that directory and clone the swift source code.
    git clone https://github.com/apple/swift.git

  3. Go into the newly cloned directory...
    cd swift

  4. Switch to/checkout the swift 3.1.1 release tag...
    git checkout swift-3.1.1-RELEASE

  5. Run the update checkout script...
    utils/update-checkout --clone --tag swift-3.1.1-RELEASE
    (If British, make tea while this runs.)

  6. If your current version of Xcode in your Applications folder is not Xcode 8.3, 8.3.1, 8.3.2 or 8.3.3, then move it aside/rename it.

  7. Download Xcode 8.3.3 or another Xcode 8.3 variant from https://developer.apple.com/downloads/

  8. Install that as /Applications/Xcode. The path must match. It must be an Xcode 8.3 version and it must be in /Applications.

  9. Go back to your source directory and run the build script...
    utils/build-script -R --clean --reconfigure

You should see it end with something like "[1170/1170] Running utility command for swift-benchmark-macosx-x86_64". You may get loads of warnings but nothing should say "error", "failed" or "fatal".

If, like me, the documentation fails to compile, you can try this patch (YMMV)...

   CACHE STRING "Paper size for generated documentation")
  1. Once it looks like it has compiled successfully, try running the test suite:
    utils/build-script -R -t

And you should get all tests passed. You now have a build swift compiler in somewhere like "build/Ninja-ReleaseAssert/swift-macosx-x86_64". Try writing a simple program and see if it works!

I hope this helps someone else one day. And thanks again to @jrose!


(Jordan Rose) #8

Glad it worked out! A tweak to steps 6 and 8: build-script will honor (and cache) the Xcode currently chosen by xcode-select, so you can temporarily switch that to point to your Xcode 8.3, build the 3.1 compiler, then go back to your normal Xcode.


(Ben Rimmington) #9

Setting the DEVELOPER_DIR environment variable also seems to work.

(export DEVELOPER_DIR=/Applications/Xcode-beta.app/Contents/Developer \
 && time ./swift/utils/build-script --clean --reconfigure)

(Carl Peto) #10

Awesome tip!
