-libnetlink and c linker

alaios · 08-31-2005, 06:13 AM

Sometimes when we compile sth we need to give to the gcc some arguments like
lib -lnetlink -lutil .
What -lnetlink stands for and where this thins is denoted so as the linker can understand this statement?

gcc -g -O2 -Dlinux -o .libs/snmpd snmpd.o ./.libs/libnetsnmpmibs.so ./.libs/libnetsnmpagent.so helpers/.libs/libnetsnmphelpers.so ../snmplib/.libs/libnetsnmp.so -lm -L/usr/src/iproute2/lib -lnetlink -lutil -ldl -Wl,--rpath -Wl,/usr/local/ucd-snmp/lib -Wl,--rpath -Wl,/usr/local/lib

I'm getting similar error 8 years later. On one day old Ubuntu 13.04.

Code:

gcc -g -ggdb -Wall -Wextra  -o mt6d mt6d.o address_worker.o tunnel_worker.o mt6d_assoc.o addr_gen.o send_utils.o if_utils.o tun_utils.o icmp_utils.o utils.o  -lcrypto -lnetfilter_queue -lssl -lnetlink -lpthread 
/usr/bin/ld: cannot find -lnetlink
collect2: error: ld returned 1 exit status

I've been trying to fix the issue for several days. I repeatedly encounter problems with libnetlink.h and similar files. I know the original post is over 8 years ago, but I'm still seeing the problem. Which is strange, because from what I understand, this is installed by default in Ubuntu 13.04, but I must be wrong.

Any help would be greatly appreciated!

Thank You,
