The sys-apps/iproute2-3.8.0 ebuild on amd64 provides a broken /usr/include/libnetlink.h header file. The header file depends on /usr/include/linux/netconf.h that is not present on my system. The linux/netconf.h header file seems to be introduced by the Linux kernel 3.8. However I got sys-kernel/linux-headers-3.7 installed on my system, and sys-apps/iproute2-3.8.0 does not depend on sys-kernel/linux-headers-3.8. After installing sys-kernel/linux-headers-3.8 manually (with ACCEPT_KEYWORDS=~amd64), libnetlink.h is not broken anymore. However, other ebuilds/application may be broken by that change, so I had to revert it. As far as I know, no ebuild seems broken by the problem described, but my own application is broken because of that problem. Reproducible: Always Steps to Reproduce: 1. Be sure to have <=sys-kernel/linux-headers-3.7 installed 2. emerge -v1 '=sys-apps/iproute2-3.8.0' 3. gcc -Wall -Werror -o test_libnetlink test_libnetlink.c Actual Results: Console output for step 3: In file included from test_libnetlink.c:4:0: /usr/include/libnetlink.h:12:27: fatal error: linux/netconf.h: No such file or directory compilation terminated. Expected Results: No console output for step 3, then: $ file test_libnetlink test_libnetlink: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not stripped Here is the small test file mentioned in steps to reproduce: $ cat test_libnetlink.c #include <stdlib.h> #include <stdio.h> #include <libnetlink.h> int main(int argc, char *argv[]) { printf("test libnetlink.h\n"); return 0; }

we can probably delete the include from the installed header as it seems like only internal code needs it ...
should be all set now in the tree; thanks for the report! Commit message: Fix building w/older linux-headers http://sources.gentoo.org/sys-apps/iproute2/iproute2-3.8.0.ebuild?r1=1.11&r2=1.12
Emerging again iproute2 fixed the problem. Thank you SpanKY! If the include is not needed, maybe this should be fixed upstream. What do you think of?
(In reply to comment #4) libnetlink is a bit of a gray area. upstream doesn't install it, but some distros do. the API can not be relied upon to be stable, and upstream keeps the header in a way that makes their lives building their code easy.

OK. Great to know! Do you know what's the "official" API recommended by upstream?
(In reply to comment #6) i don't think there is one
