From: Changqing Li <[email protected]> Go packages and binaries are stamped with build IDs that record both the action ID, which is a hash of the inputs to the action that produced the packages or binary, and the content ID, which is a hash of the action output, namely the archive or binary itself, Refer [1].
And action ID include hash of modroot, which will include build path, so this make go package not reproducible. Refer [2], keying off module path instead of module root directory is a TODO. [snip of log] HASH[moduleIndex]: "go1.25.3" HASH[moduleIndex]: "modroot /build-a/tmp/work/x86-64-v3-wrs-linux/buildah/1.41.5/recipe-sysroot-native/usr/lib/go/src/cmd\n" HASH[moduleIndex]: "package go1.25.3 go index v2 /build-a/tmp/work/x86-64-v3-wrs-linux/buildah/1.41.5/recipe-sysroot-native/usr/lib/go/src/cmd/buildid\n" HASH[moduleIndex]: "file buildid.go 2025-10-13 16:08:43 +0000 UTC 1704\n" HASH[moduleIndex]: "file doc.go 2025-10-13 16:08:43 +0000 UTC 558\n" HASH[moduleIndex]: 007b9fe2edd5b3232f5c98ae6c46e80a435141cb627ba5418c5314c0cbf4df7b Report this issue to upstream, refer [3] Workaround the reproducible by setting buildid to empty, refer [4] Refer: [1] https://github.com/golang/go/blob/master/src/cmd/go/internal/work/buildid.go#L26 [2] https://github.com/golang/go/blob/master/src/cmd/go/internal/modindex/read.go#L70 [3] https://github.com/golang/go/issues/77086 [4] https://github.com/golang/go/issues/34186 Signed-off-by: Changqing Li <[email protected]> --- meta/classes-recipe/go.bbclass | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/meta/classes-recipe/go.bbclass b/meta/classes-recipe/go.bbclass index b540471ba2..1c43b36fc0 100644 --- a/meta/classes-recipe/go.bbclass +++ b/meta/classes-recipe/go.bbclass @@ -51,11 +51,12 @@ GO_RPATH:class-native = "${@'-r ${STAGING_LIBDIR_NATIVE}/go/pkg/${TARGET_GOTUPLE GO_RPATH_LINK:class-native = "${@'-Wl,-rpath-link=${STAGING_LIBDIR_NATIVE}/go/pkg/${TARGET_GOTUPLE}_dynlink' if d.getVar('GO_DYNLINK') else ''}" GO_EXTLDFLAGS ?= "${HOST_CC_ARCH}${TOOLCHAIN_OPTIONS} ${GO_RPATH_LINK} ${LDFLAGS}" GO_LINKMODE ?= "" +GO_BUILDID ?= "-buildid=" GO_EXTRA_LDFLAGS ?= "" GO_LINUXLOADER ?= "-I ${@get_linuxloader(d)}" # Use system loader.
