Hello,
I'm new to Swift repository.
I made some changes for diagnostic, and I tried to build toolchain to use the updated Swift toolchain in Xcode.
However, if I run the command bellow, I came across the architecture related error: Undefined symbols for architecture x86_64
I run the command on M1 and M3 Max macs, but both of them are in the same situation.
Also, if I tried a clean build, removing --macos-only flag or --sccache flag, or discarding changes, the situation didn't changed.
If anyone knows of a solution, I would like to know.
Best regards,
Yu Takahashi
Environment
- Branch: main (swiftlang/swift)
- Chip: M1 / M3 Max
- OS: macOS 15.5
- Storage: Enough space
Command: ./utils/build-toolchain $BUNDLE_PREFIX --macos-only --sccache
