You should be able to install the Debian 10 package on Ubuntu 19.04. Just alter the instructions from https://deb.frrouting.org/ and replace the "$(lsb_release -s -c)" with "buster": echo "deb https://deb.frrouting.org/frr buster frr-stable" | ... Cheers, -David

How to build FRR with snmp supported ?
by Simon Jones 02 Aug '19

02 Aug '19

Hi all, I'm working on FRR, and I want bgpd and zebra to support snmp like this ( http://docs.frrouting.org/en/latest/snmp.html) As I want to handle peer down/up events. So I use this script to build : .ONESHELL: SHELL = /bin/bash .SHELLFLAGS += -e MAIN_TARGET = $(FRR) DERIVED_TARGET = $(FRR_PYTHONTOOLS) $(FRR_DBG) $(addprefix $(DEST)/, $(MAIN_TARGET)): $(DEST)/% : # Build the package pushd ./frr tools/tarsource.sh -V -e '-sonic' dpkg-buildpackage -rfakeroot -b -us -uc -Ppkg.frr.nortrlib -j$(SONIC_CONFIG_MAKE_JOBS) popd mv $(DERIVED_TARGET) $* $(DEST)/ $(addprefix $(DEST)/, $(DERIVED_TARGET)): $(DEST)/% : $(DEST)/$(MAIN_TARGET) In build log, I found there are zebra_snmp.so, and I found in this folder > $ find -name zebra_snmp.so > ./frr/zebra/.libs/zebra_snmp.so > ./frr/debian/frr-snmp/usr/lib/x86_64-linux-gnu/frr/modules/zebra_snmp.so > ./frr/debian/tmp/usr/lib/x86_64-linux-gnu/frr/modules/zebra_snmp.so But at last, in deb package, this is no zebra_snmp.so and other snmp.so in modules folder, and actually there is no modules folder. So how to build with these modules and snmp support like that URL? Will this be work? 1. Add '-Ppkg.frr.snmp' in 'dpkg-buildpackage' step? Or 2. Use some old version? Thank you~ ---- Simon Jones
