The 089d0c53ea40c841baee0cd2eecd7844a31cfa90 "net-snmp: Fix host contamination" commit in WRL8 RCPL0027 appears to break the generation of the net-snmp-config leaking "--sysroot=" and "--with-libtool-sysroot=" where the wrl8 projects sysroot directory has been removed but the empty assignment remains breaking attempts to use net-snmp-config in a cross-compile environment.
The commit affects this trailing sed statement in the do_install_append() by removing all instances of the $STAGING_DIR_TARGET paths. This trailing sed used to properly manage the removal of the sysroot option and path constructs. By stripping the sysroot staging dir path initially, the isolated --option= remains in the rcpl27 generated net-snmp-config.
do_install_append() {
install -d ${D}${sysconfdir}/snmp
...
sed -e "s@--sysroot=${STAGING_DIR_TARGET}@@g" \
-e "s@--with-libtool-sysroot=${STAGING_DIR_TARGET}@@g" \
-e "s@${STAGING_DIR_TARGET}@@g" \
-i ${D}${bindir}/net-snmp-config \
-i ${D}${includedir}/net-snmp/net-snmp-config.h
}
Here is an example of the isolated "--syroot=" artifacts:
