From 4c0daa80c0df0abae600e56bf3df0b91f318d1bb Mon Sep 17 00:00:00 2001 From: jusherma Date: Wed, 4 Aug 2021 00:56:29 -0700 Subject: [PATCH] [build] Always use -j1 for libsnmp to avoid race condition (#8324) I have been seeing intermittent (~40%) build failures with the same error described in PR https://github.com/Azure/sonic-buildimage/pull/6592, even with that fix present ``` /usr/bin/ld: mibgroup/ip-forward-mib/ipCidrRouteTable/.libs/ipCidrRouteTable_interface.o: file not recognized: file truncated ... libtool: error: 'mibgroup/ip-forward-mib/inetCidrRouteTable/inetCidrRouteTable_interface.lo' is not a valid libtool object make[5]: *** [Makefile:1020: libnetsnmpmibs.la] Error 1 make[5]: *** Waiting for unfinished jobs.... ``` #### How I did it Use `-j1` for the libsnmp build regardless of the value of `$(MULTIARCH_QEMU_ENVIRON)` #### How to verify it Performed 10 builds of the libsnmp target (`target/debs/buster/libsnmp-base_5.7.3+dfsg-5_all.deb`) with and without this change. Without the change, hit the error 40% of the time. With the change did not see the error at all Signed-off-by: Justin Sherman --- src/snmpd/Makefile | 4 ---- 1 file changed, 4 deletions(-) diff --git a/src/snmpd/Makefile b/src/snmpd/Makefile index af225cfe61..50d0303540 100644 --- a/src/snmpd/Makefile +++ b/src/snmpd/Makefile @@ -29,11 +29,7 @@ $(addprefix $(DEST)/, $(MAIN_TARGET)): $(DEST)/% : stg init stg import -s ../patch-$(SNMPD_VERSION)/series -ifeq ($(MULTIARCH_QEMU_ENVIRON), y) dpkg-buildpackage -rfakeroot -b -d -us -uc -j1 --admindir $(SONIC_DPKG_ADMINDIR) -else - dpkg-buildpackage -rfakeroot -b -d -us -uc -j$(SONIC_CONFIG_MAKE_JOBS) --admindir $(SONIC_DPKG_ADMINDIR) -endif popd mv $(DERIVED_TARGETS) $* $(DEST)/
