Hi, The build script has found a valid problem, but is giving an incorrect error message.
The message: checking whether C compiler supports flag "-g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/net-snmp-5.9.5.2+dfsg=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -DNETSNMP_USE_INLINE -DNETSNMP_ENABLE_IPV6 -fno-strict-aliasing -DNETSNMP_REMOVE_U64 -Werror=declaration-after-statement -g -O2 -ffile-prefix-map=/build/reproducible-path/net-snmp-5.9.5.2+dfsg=. -fstack-protector-strong -fstack-clash-protection -Wformat -fcf-protection -DNETSNMP_USE_INLINE -Ulinux -Dlinux=linux -D_REENTRANT -D_GNU_SOURCE -DDEBIAN -fwrapv -fno-strict-aliasing -pipe -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/lib/x86_64-linux-gnu/perl/5.40/CORE -I/usr/include/libnl3 -I/usr/include/libnl3 -Wdate-time -D_FORTIFY_SOURCE=2 -I/usr/include -Wl,-z,relro -Wl,-z,now -fcf-protection -L/usr/lib/x86_64-linux-gnu -lnetsnmpmibs -lsensors -lpci -lnl-route-3 -lnl-3 -lm -lnetsnmpagent -lwrap -Wl,-E -lnetsnmp -lm -lssl -lssl -lssl -lssl -lcrypto" from Net-SNMP... no configure: error: *** incorrect CFLAGS from net-snmp-config Not quite, looking at the build log shows: configure:23483: checking whether C compiler supports flag "-g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/net-snmp-5.9.5.2+dfsg=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -DNETSNMP_USE_INLINE -DNETSNMP_ENABLE_IPV6 -fno-strict-aliasing -DNETSNMP_REMOVE_U64 -Werror=declaration-after-statement -g -O2 -ffile-prefix-map=/build/reproducible-path/net-snmp-5.9.5.2+dfsg=. -fstack-protector-strong -fstack-clash-protection -Wformat -fcf-protection -DNETSNMP_USE_INLINE -Ulinux -Dlinux=linux -D_REENTRANT -D_GNU_SOURCE -DDEBIAN -fwrapv -fno-strict-aliasing -pipe -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/lib/x86_64-linux-gnu/perl/5.40/CORE -I/usr/include/libnl3 -I/usr/include/libnl3 -Wdate-time -D_FORTIFY_SOURCE=2 -I/usr/include -Wl,-z,relro -Wl,-z,now -fcf-protection -L/usr/lib/x86_64-linux-gnu -lnetsnmpmibs -lsensors -lpci -lnl-route-3 -lnl-3 -lm -lnetsnmpagent -lwrap -Wl,-E -lnetsnmp -lm -lssl -lssl -lssl -lssl -lcrypto" from Net-SNMP configure:23502: gcc -o conftest -g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -isystem /usr/include/x86_64-linux-gnu/bsd -DLIBBSD_OVERLAY -g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/net-snmp-5.9.5.2+dfsg=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -DNETSNMP_USE_INLINE -DNETSNMP_ENABLE_IPV6 -fno-strict-aliasing -DNETSNMP_REMOVE_U64 -Werror=declaration-after-statement -g -O2 -ffile-prefix-map=/build/reproducible-path/net-snmp-5.9.5.2+dfsg=. -fstack-protector-strong -fstack-clash-protection -Wformat -fcf-protection -DNETSNMP_USE_INLINE -Ulinux -Dlinux=linux -D_REENTRANT -D_GNU_SOURCE -DDEBIAN -fwrapv -fno-strict-aliasing -pipe -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/lib/x86_64-linux-gnu/perl/5.40/CORE -I/usr/include/libnl3 -I/usr/include/libnl3 -Wdate-time -D_FORTIFY_SOURCE=2 -I/usr/include -Wdate-time -D_FORTIFY_SOURCE=2 -Wl,-z,relro -fcf-protection conftest.c -lbsd -Wl,-z,relro -Wl,-z,now -fcf-protection -L/usr/lib/x86_64-linux-gnu -lnetsnmpmibs -lsensors -lpci -lnl-route-3 -lnl-3 -lm -lnetsnmpagent -lwrap -Wl,-E -lnetsnmp -lm -lssl -lssl -lssl -lssl -lcrypto >&5 /usr/bin/ld: cannot find -lnl-route-3: No such file or directory /usr/bin/ld: cannot find -lnl-3: No such file or directory This (the missing libraries) is the actual issue. Already reported in #1124219 and fixed in net-snmp 5.9.5.2+dfsg-2 which I'll upload shortly. I think you just have to wait for that to appear and this will be fixed. - Craig
