From 3251fe210a91d13ab2a6c5b7ecb283aa8e019020 Mon Sep 17 00:00:00 2001 From: Paul Eggleton Date: Sun, 14 Jun 2020 21:28:45 -0700 Subject: protobuf-c: disable parallelism to avoid race condition Unfortunately 489d3b4b932ee8016d792341f8ea5836a9522cd4 did not completely fix the problem - if you try cleaning and rebuilding protobuf-c-native it doesn't take long to reproduce the issue on a 32-core machine. I spent some time trying to debug this but failed, there is still a race between generating t.test-full.pb.h and compiling cxx_generate_packed_data.c despite BUILT_SOURCES and explicit dependencies. I even tried converting the multiple target rules to use grouped targets (&:), that didn't fix it either. Disabling parallelism as a workaround only costs ~20s and it turns out that upstream is switching to Meson soon anyway: https://github.com/protobuf-c/protobuf-c/pull/340 Signed-off-by: Paul Eggleton Signed-off-by: Khem Raj --- meta-oe/recipes-devtools/protobuf/protobuf-c_1.3.3.bb | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'meta-oe/recipes-devtools/protobuf') diff --git a/meta-oe/recipes-devtools/protobuf/protobuf-c_1.3.3.bb b/meta-oe/recipes-devtools/protobuf/protobuf-c_1.3.3.bb index bb8aecded3..6fef0bed2c 100644 --- a/meta-oe/recipes-devtools/protobuf/protobuf-c_1.3.3.bb +++ b/meta-oe/recipes-devtools/protobuf/protobuf-c_1.3.3.bb @@ -22,6 +22,11 @@ S = "${WORKDIR}/git" inherit autotools pkgconfig +# After several fix attempts there is still a race between generating +# t.test-full.pb.h and compiling cxx_generate_packed_data.c despite +# BUILT_SOURCES and explicit dependencies. +PARALLEL_MAKE = "" + PACKAGE_BEFORE_PN = "${PN}-compiler" FILES_${PN}-compiler = "${bindir}" -- cgit 1.2.3-korg
