问题
I am trying to use libnl 3 (http://www.infradead.org/~tgr/libnl/) under Ubuntu to use netlink in order to get some information from the IPv6 Neighbour Cache.
I am including a bunch of headers for this lib, but gcc already fails for the first one:
#include <libnl3/netlink/netlink.h>
There is no "main header", like libnl.h.
>$ gcc netlink_test.c
In file included from netlink_test.c:11:0:
/usr/include/libnl3/netlink/netlink.h:24:36: fatal error: netlink/netlink-compat.h: No such file or directory
compilation terminated.
The file netlink.h includes "netlink/netlink-compat.h". Unfortunately, there is no "/usr/include/netlink/" folder. There is only "/usr/include/libnl3/netlink/"
Including "netlink/netlink.h" thus gives me:
netlink_test.c:10:29: fatal error: netlink/netlink.h: No such file or directory
compilation terminated.
I have installed the following packages under Ubuntu 12.04:
libnl-3-200
libnl-3-200-dbg
libnl-3-dev
libnl-3-doc
libnl-genl-3-200
libnl-genl-3-200-dev
libnl-route-3-200
libnl-route-3-200-dev
Am I missing here something or is this genuinely broken?
回答1:
OK, so the package is not broken, I am ;)
A short while ago, they introduced a mechanism to enable users to install different versions of this library. Now you can configure it using "pkg-config" or just pass the precise directory to the compiler with "-I /usr/include/libnl3/". And it works.
