Compiler build fails (Multiple commands)

Development Compiler
1

I have just forked and cloned master and tried running the build script with the following parameters.

./utils/build-script --release-debuginfo --xcode --clean

I'm getting this error.

Build system information
error: Multiple commands produce '/Users/myuser/workspace/swift-source/build/Xcode-    RelWithDebInfoAssert/swift-macosx-x86_64/RelWithDebInfo/lib/libBlocksRuntime.dylib':

This is what I'm using:

  • M1
  • Xcode 12.3
  • cmake version 3.19.4
  • ninja 1.10.2

Any help would be welcome

That seems like a bug. Can you try adding --swift-darwin-supported-archs="$(uname -m)" and see if that fixes the issue? (Also, you may want to see the Getting Started guide in case you haven't already.)

Following the getting started guide and doing

./utils/build-script --skip-build-benchmarks --skip-ios --skip-watchos --skip-tvos --swift-darwin-supported-archs "$(uname -m)" --release-debuginfo --swift-disable-dead-stripping --test --Xcode

I'm getting this error

    ptrAuthEnabled = (triple.getSubArch() == Triple::AArch64SubArch_E);

If I clean the build folder and run

./utils/build-script --release-debuginfo --swift-darwin-supported-archs="$(uname -m)" --Xcode

I'll get this...

Should I raise a ticket for that @Varun_Gandhi ?
