About LIBNL_GENL...

[yxungh]

Hi!
When I compile the openvpn-dco, an error occurs,

configure: error: libnl-genl-3.0 package not found or too old. Is the development package and pkg-config installed? Must be version 3.4.0 or newer

My environment: centos 5.4.168-1.el7.elrepo.x86_64
gcc version 9.3.1 20200408 (Red Hat 9.3.1-2) (GCC)

and
ls /usr/lib/libnl*

/usr/lib/libnl-3.la /usr/lib/libnl-genl-3.so.200 /usr/lib/libnl-route-3.la
/usr/lib/libnl-3.so /usr/lib/libnl-genl-3.so.200.26.0 /usr/lib/libnl-route-3.so

/usr/lib/libnl-genl-3.so /usr/lib/libnl-nf-3.so.200.26.0

I am not too knowledgeable about libnl,Version 3.4 is required?
but on the site http://www.infradead.org/~tgr/libnl/
The latest stable release is: 3.2.25

Is there a openvpn-dco environment configuration list?
