# FRRouting Configuration options
######################################
#
#    WANT_xxxx   --> Set to 1 for enable, 0 for disable
# The following are the defaults. They can be overridden by setting a 
# env variable to a different value

# -Werror - don't enable this unless you're doing a dev package build
WANT_WERROR ?= 0

WANT_OSPFAPI ?= 1
WANT_BGP_VNC ?= 1
WANT_CUMULUS_MODE ?= 0
WANT_MULTIPATH ?= 1
WANT_SNMP ?= 0
WANT_RPKI ?= 0

# NOTES:
#
# If you use WANT_RPKI, then there is a new dependency for librtr0 package
#    and a build dependency of the librtr-dev package.
#    While the librtr0 is added to the depenencies automatically, the build
#    dependency can't be changed dynamically and building will fail if the
#    librtr-dev isn't installed during package build
#    Tested versions of both packages can be found at
#    https://ci1.netdef.org/browse/RPKI-RTRLIB/latestSuccessful/artifact
#
# If multipath is enabled (WANT_MULTIPATH=1), then set number of multipaths here
#    Please be aware that 0 is NOT disabled, but treated as unlimited

MULTIPATH ?= 256

# Set the following to the value required (or leave alone for the default below)
# WANT_FRR_USER is used for the username and groupname of the FRR user account

WANT_FRR_USER ?= frr
WANT_FRR_VTY_GROUP ?= frrvty

# Don't build PDF docs by default
# add build deps: texlive-latex-base, texlive-generic-recommended
GENERATE_PDF ?= 0
