Build keeps failing

[lawrencebensaid]

Hi all,

I'm a bit stuck. For a while I've been trying to get Swift to build for my ESP32 C6, but it keeps getting stuck in one of the last stages. I followed all the steps as described in esp32-led-strip-sdk/README.md.

Can someone point me in the right direction?

Versions:

$ idf.py --version
ESP-IDF v5.2.2-500-g2cd9da52fe

$ swift --version 
swift-driver version: 1.113 Apple Swift version 6.0 (swiftlang-6.0.0.7.6 clang-1600.0.24.1)
Target: arm64-apple-macosx15.0

Build logs:

Any suggestions of help would be greatly appreciated 🙏🏼
Thanks!

The error message includes:

/Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc ...

which means you are using Swift from the Xcode installation, but that won't work, you need to use a downloaded toolchain from swift.org. Did you maybe forget to export TOOLCHAINS=... before running idf.py set-target?

[rauhul]

Closing this as stale, I believe Kuba's diagnosis is correct and moving to a nightly toolchain will resolve this issue. We now have CI that covers building this example which can also be used as a reference.
