I was trying to compile
libnetfilter_conntrack source from github as it was requested by
iptables while compiling iptables and as any of these were not available in the HURD software repo and ended up in an error while configuring
checking whether stripping libraries is possible... yes checking if libtool supports shared libraries... yes checking whether to build shared libraries... yes checking whether to build static libraries... no checking whether ln -s works... yes configure: error: Linux only, dude!
and my kernel is,
$ uname -a GNU debian 0.9 GNU-Mach 1.8+git20190109-486/Hurd-0.9 i686-AT386 GNU
and my ultimate goal was to compile iproute2.
