2025 update: This is now possible.
I've built a Pure-Go race detector that works with CGO_ENABLED=0:
https://github.com/kolkov/racedetector
Works in:
- Alpine/scratch Docker containers
- AWS Lambda / Cloud Functions
- Cross-compilation scenarios
- Any CGO_ENABLED=0 environment
Usage:
go install github.com/kolkov/racedetector/cmd/racedetector@latest
racedetector build -o myapp main.go
It's a standalone tool (not runtime integration yet), but it detects
races without any CGO dependency. FastTrack algorithm, 15-22% overhead,
pure Go.
Feedback welcome: https://github.com/kolkov/racedetector/discussions
Best regards!

I'm building my service without CGO, so ideally, I'd like to run my tests
with the same settings, and I really like race detection. Is there any way
to use the race detector with CGO_ENABLED=0?
