Hello everyone,
I’m trying to build the Swift project for the first time and I’m running
into a linker error related to MetalKit. I’ve followed the instructions on
the Swift Github but the process fails. I’ve run out things I can think of
to try, I hope someone can point me in the right direction.
I’m running Xcode 9.1 Beta 2 (9B46) on Mac OS 10.12.6 (ci-swift.org also
uses this version).
I’ve tried several things at no avail:
- Install the Xcode beta next to the release version and use xcode-select
- Run the build script without options
- Removed the build folder and try again several times again with different
options (—reconfigure, -x)
- Removed both Xcode’s and only install the beta version as Xcode.app,
tried to build several times again
- Removed my whole swift-source folder, cloned everything again, install
Xcode beta again and try to build
When I build the project with -x an Xcode project is generated and I can
build some targets, but not everything.
I’ve also searched this mailing list and couldn’t find anything I haven’t
tried yet.Does anybody have any idea what I could to do to fix this?
These are the errors I’m seeing when building with ninja and xcodebuild:
