Invoking SwiftPM from open source toolchain crashes because symbols are defined both in system stdlib and toolchain stdlib

[ahoppen]

Running any SwiftPM command from an open source toolchain crashes because there are symbols defined both in the system stdlib and the stdlib shipped as part of the toolchain.

This affects both main and 5.7 snapshot toolchains. Things must have broken sometime between 2/22 and 4/4. swift-DEVELOPMENT-SNAPSHOT-2022-02-22-a.xctoolchain still works while swift-DEVELOPMENT-SNAPSHOT-2022-04-04-a.xctoolchain doesn’t (I don’t have any intermediate toolchains installed to check)

Steps to reproduce

mkdir mypackage
$ cd mypackage
$ swift package init

@ahoppen could this be a problem specific to your setup? we have tests that validate the nightly toolchains including that SwiftPM is functional, and I would be surprised if we did not hear about this before.

cc @shahmishal @abertelrud in case they have insight

[ahoppen]

I don’t think this is specific to my setup. It was brought to my attention by @kimdv and he’s seeing the same issue.

I'm seeing a very similar issue when trying to build swift-format using SwiftPM with an open source toolchain. I've tried the following open source toolchains, and gotten the same results in both:

• swift-DEVELOPMENT-SNAPSHOT-2022-05-04-a.xctoolchain

yea odd, it must be some search path that exists on your machines but no on mine

[tomerd]

interesting to see what @shahmishal sees on the CI & smoke tests that should catch this

[adam-fowler]

I reported the same here swiftlang/swift#58658

[WowbaggersLiquidLunch]

I see the same error messages when trying to use the open-source toolchain in CLion on macOS.

I'm running into the same issue, building main branches from scratch. Some more info:

• I'm using Xcode 13 beta 4 as recommended
• macOS version 12.3.1
• I tried compiling with both --use-os-runtime and without
• Removing the copy of the libraries in the .xctoolchain path (expectedly) fixes the issue

Other than that the build machine is very vanilla. There are a small number of homebrew packages installed, several versions of Xcode (13.3, 13.3.1), and that is basically it.

[tomerd]

this was worked around in 5.7 via #4323 which should be in the recent version of 5.7 (but not main). the plan is to fix properly in main

Yep, swift-5.7-DEVELOPMENT-SNAPSHOT-2022-05-10-a seems to work for me.

[ahoppen]

Also verified that swift-5.7-DEVELOPMENT-SNAPSHOT-2022-05-10-a works for me.

[kimdv]

swift-5.7-DEVELOPMENT-SNAPSHOT-2022-05-10-a works also for me.
