I'm using an older buildroot 2016.11 and want to add DNS-SD by selecting the avahi package. Resulting in this error:
Unescaped left brace in regex is illegal here in regex; marked by <-- HERE in m/^(.*)\${ <-- HERE ?([A-Z_]+)}?(.*)$/ at /home/user/nuvoton/nuc980/output/host/usr/bin/intltool-update line 1065.
checking for intltool >= 0.35.0... found
configure: error: Your intltool is too old. You need intltool 0.35.0 or later.
When searching I learned intltool should be enabed on the host, but I could not find how in menuconfig. More searching told me it is related to some Perl update I tried adding this patch http://lists.busybox.net/pipermail/buildroot/2017-June/194509.html but that also didn't help.
Can somebody steer me in the right direction how to solve this?
