The update to 1.43.0 combined with otel 1.43.0-2 (which now ships exporters/prometheus) fixes this FTBFS. MR: https://salsa.debian.org/go-team/packages/golang-opentelemetry-contrib/-/merge_requests/3
I introduced these changes in the MR: - Removed bridges/prometheus from DH_GOLANG_EXCLUDES (can now build with otel 1.43.0-2) - Added golang-github-prometheus-client-golang-dev and golang-github-prometheus-otlptranslator-dev to Build-Depends - Updated otel dependency to >= 1.43.0-2 With those changes, dh-golang automatically builds and tests both bridges/prometheus and exporters/autoexport. Clean sbuild results: ok go.opentelemetry.io/contrib/bridges/prometheus 0.020s ok go.opentelemetry.io/contrib/exporters/autoexport 0.079s All 11 test suites pass, 0 failures. I am CCing: Andrew with whom I am coordinating to do the version bumps for the otel/collector/auto ecosystem uploads. Cheers, Juan
