Re: [PATCH] configure: fix libnl-3 detection and rework libnl configure check (v3)
That seems to work on most my systems.
I do get an error with slightly older automake.
how about this for a fix?
error to fix is
configure.ac:19: warning: macro `AM_PROG_AR' not found in library
autoreconf: running: /usr/bin/autoconf
configure.ac:19: error: possibly undefined macro: AM_PROG_AR
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
autoreconf: /usr/bin/autoconf failed with exit status: 1
