Bug 420759 – net-wireless/crda-1.1.2-r3 has libnl:3 automagic

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Nikoli 2012-06-12 05:33:10 UTC]

* Checking dynamic linking consistency
[ 3% ]  *   broken /sbin/crda (requires libnl-3.so.200
libnl-genl-3.so.200)
[ 100% ]

Please change dep to libnl:3 or add USE.

Confirmed here to : when libnl:3 is present on the system, crda links against libnl:3, not libnl:1. Looking at the makefile, it seems that it automatically links against the highest libnl version.

# ldd /sbin/crda 
        linux-vdso.so.1 (0x0000034bfd36b000)
        libcrypto.so.1.0.0 => /usr/lib64/libcrypto.so.1.0.0 (0x0000034bfcd7f000)
        libnl-genl-3.so.200 => /usr/lib64/libnl-genl-3.so.200 (0x0000034bfcb7a000)
        libnl-3.so.200 => /usr/lib64/libnl-3.so.200 (0x0000034bfc960000)
        libc.so.6 => /lib64/libc.so.6 (0x0000034bfc5be000)
        libdl.so.2 => /lib64/libdl.so.2 (0x0000034bfc3ba000)
        libz.so.1 => /lib64/libz.so.1 (0x0000034bfc1a4000)
        libpthread.so.0 => /lib64/libpthread.so.0 (0x0000034bfbf88000)
        libm.so.6 => /lib64/libm.so.6 (0x0000034bfbc97000)
        /lib64/ld-linux-x86-64.so.2 (0x0000034bfd14c000)


So the libnl depend should probably be adjusted (to no version, like net-wireless/iw ?).
Otherwise, it should be patched to depend explicitly on a specific libnl version. This should be easy, commenting libnl version on lines 48,49,50 of the Makefile to block version detection : https://github.com/mcgrof/crda/blob/master/Makefile

Fixed, now it depends on dev-libs/libnl, not dev-libs/libnl:1.1

[Comment 3 Ryan Hill (RETIRED) 2012-06-18 05:16:19 UTC]

That doesn't really fix the bug - crda is still linking against the latest installed SLOT.  It just makes portage pull libnl:3 into the dependency graph even if crda was already built against libnl:1.  You might as well just depend on dev-libs/libnl:3 if you're going to force everyone to install it anyway.

This would be particularly useful since dev-libs/libnl:3 is actively maintained upstream, whereas dev-libs/libnl:1 hasn't been for a long time.

Fixed, 1.1.2-r4 now depends on libnl:3 instead of just libnl.
