Yes, I agree this, I just mean "not install genl is not the excuse of fail
to configure in _above_ cases".
sorry, not sure.
missing dependency is a very good reason to fail configure. in fact, configure is
performed
to validate system if it fits minimum build requirements. and in our case missing libnl
and libnl-genl are a show stoppers.
but yes, we have a problem with that ubuntu package mess that we have to address.
After double check, in libnl-3 of ubuntu 11.10 (sorry, I wrote it
as 11.04
in above email) includes these content of lib-genl, so in 11.10, no
libnl-genl, which only is in 12.04, where the nl version is: 3.2.3.
and for libnl2, also no genl.
is this correct?
ubuntu libnl-3.*.so libnl-genl-3.*.so libnl-2.*.so libnl-genl-2.*.so
11.10 + - + -
12.04 + + + +
is 11.10 still supported? if support for that version is discontinued then I'm not
sure
we really must care.

disagree, successful configure itself is useless, build is the one that
matters.
if one does not have all requirements for build, failed configure is ok.
