• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Adrian Bassett 2011-11-01 10:08:37 UTC]

net-wireless/iw-3.1 fails to compile.

Diagnostic is '/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/../../../../x86_64-pc-linux-gnu/bin/ld: cannot find -lnl-genl'

Both libnl-1.1-r2 and libnl-3.2.2 are installed.

# ls /usr/lib/libnl-genl*
lrwxrwxrwx 1 root root    23 Oct 31 09:24 /usr/lib/libnl-genl-3.so -> libnl-genl-3.so.200.2.0
lrwxrwxrwx 1 root root    23 Oct 31 09:24 /usr/lib/libnl-genl-3.so.200 -> libnl-genl-3.so.200.2.0
-rwxr-xr-x 1 root root 19392 Oct 31 09:24 /usr/lib/libnl-genl-3.so.200.2.0

Reproducible: Always

emerge log for iw-3.1 against libnl-3.2.2

[Comment 2 Jeroen Roovers (RETIRED) 2011-11-01 16:07:21 UTC]

That's odd. I already downgraded its dep to dev-libs/libnl:1.1 for another bug report, so that dependency should probably be fixed as well (and just let upstream handle libnl:3 support).

[Comment 3 Jeroen Roovers (RETIRED) 2011-11-01 16:09:31 UTC]

Not applying the patch (and thusly expecting no specific version like 1 or 2 or 3) has it compiling nicely against 1.1...

Fixed, please allow the mirrors to catch up before you emerge --sync and test.

Thanks - iw-3.1 now recompiles OK without the need for changes to libnl and links against v1 of libnl.

A patch has been applied to the Makefile in the master branch of the iw git repository (15bc193a926ec67e25de175f7dfe45df8cbd3e9a) such that iw now compiles against libnl-3.2.2,

# ldd /usr/local/sbin/iw
	linux-vdso.so.1 =>  (0x00007fff89dff000)
	libnl-genl-3.so.200 => /usr/lib64/libnl-genl-3.so.200 (0x00007fcc9c748000)

	libpthread.so.0 => /lib64/libpthread.so.0 (0x00007fcc9bf6a000)

I have bumped iw to 3.2, and added the patch 9c1d758129e02af5623b4faa52342b8bae3f5fd9 from the upstream git, including a little change I made to it, to make it work.

[Comment 8 Arfrever Frehtes Taifersar Arahesis 2011-11-14 12:54:54 UTC]

net-wireless/iw-3.2 still has RDEPEND="dev-libs/libnl:1.1".

[Comment 9 Bjarke Istrup Pedersen (RETIRED) 2011-11-14 13:15:03 UTC]

Fixed, now it only depends on dev-libs/libnl
