Problems with build-script –xcode

Development Compiler
1

Hi, I’m encountering an error with the main branch and the swift-DEVELOPMENT-SNAPSHOT-2024-10-30-a tag when running the following command:

utils/build-script --swift-darwin-supported-archs "$(uname -m)" --xcode --clean

The error message is as follows:

CMake Error at cmake/modules/SwiftXcodeSupport.cmake:21 (message):
  No import configuration of clang-resource-headers specified?!
Call Stack (most recent call first):
  cmake/modules/SwiftXcodeSupport.cmake:88 (check_imported_target_has_imported_configuration)
  cmake/modules/SwiftSharedCMakeConfig.cmake:213 (fix_imported_targets_for_xcode)
  cmake/modules/SwiftSharedCMakeConfig.cmake:255 (swift_common_standalone_build_config_clang)
  CMakeLists.txt:915 (swift_common_standalone_build_config)

There are no issues when I run this alternative command:

utils/build-script --skip-build-benchmarks \
  --skip-ios --skip-watchos --skip-tvos --swift-darwin-supported-archs "$(uname -m)" \
  --sccache --release-debuginfo --swift-disable-dead-stripping \
  --bootstrapping=hosttools --clean

This problem doesn’t occur when using the swift-DEVELOPMENT-SNAPSHOT-2024-10-27-a tag.

My Environment:

  • Macbook Pro Apple M2 Pro
  • macOS Sequoia 15.1
  • CMAKE 3.24.2

Please let me know if any additional information would be helpful.

Thank you in advance for your help.

Hmm, the check requiring imported targets to have a specific imported configuration seems overly aggressive. The clang-resource-headers doesn't specify which configurations it needs to be included with.

Could you try copying this diff:

and running pbpaste | git apply from within the Swift compiler repo.
Please verify that it configures (I expect that it will) and gives you the expected Xcode experience. Thanks.

Thank you for the reply.

I tried it and got the below error.

FYI we have recently introduced a new way to generate an Xcode project for the Swift repo: A new way to work on the Swift project in Xcode. Feel free to give it a try!

Thank you!

It works well. It's very fast and convenient.

BTW, the below command works.

utils/generate-xcode <build dir>

but, the below one didn't work.

./swift-xcodegen <path to Ninja build directory>

Where do we run the command?

The README could probably be a bit clearer there, but ./swift-xcodegen is assuming you're in the utils/swift-xcodegen folder. utils/generate-xcode directly runs it though, so it's better to use that instead.

I see. Thanks!

Updating the README in [xcodegen] Update README by hamishknight · Pull Request #77428 · swiftlang/swift · GitHub, hopefully that improves things.
