objdump -T libnetsnmpagent.so.15|grep netsnmp_enable_subagent 0000000000023b00 g DF .text 0000000000000041 Base netsnmp_enable_subagent Seems the symbol is present. Is this a bug in the test within lldpd?
Which version of net-analyzer/net-snmp is that?
Last line of bugreports states: net-analyzer/net-snmp-5.4.3 For completeness again: [ebuild R ] net-analyzer/net-snmp-5.4.3 USE="X bzip2 extensible ipv6 perl python ssl tcpd zlib -diskio -doc -elf -lm_sensors -mfd-rewrites -minimal -rpm (-selinux) -sendmail -smux" 0 kB btw, I reemerged net-snmp after first hitting the configure error, just to make sure, but that did not change anything. From what I checked so far everything seems to be in place, do you need any more detailed logs (i.e. the whole configure log and emerge log)? It puzzles me though, that the test fails in the first place, since all linked (-l) libs are in place and the corresponding lib has the necessary symbol, so ld should be able to resolve it. Could any other linker option cause something like that? (Specifically as-needed?)
Maybe following commit addresses the problem?! https://github.com/vincentbernat/lldpd/commit/8d72aaa09c1978bf75884a0dde4e0a7cd419332d
Seems the problem was fixed in 0.5.7, maybe do a version bump?
The patch looks correct to me, so I suggest just bumping this.
net-misc/lldpd-0.5.7 is now in portage.
