Undefined reference to symbol 'pthread_create@@GLIBC_2.2.5



I am compiling citrusleaf_client_libevent2_2.1.41 on ubuntu 14

ubuntu@ip-10-186-144-184:~/citrusleaf_client_libevent2_2.1.41$ cat /proc/version
Linux version 3.13.0-44-generic (buildd@lamiak) (gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) ) #73-Ubuntu SMP Tue Dec 16 00:22:43 UTC 2014

and I am getting the following error:

I am following http://www.aerospike.com/docs/client/libevent/build/debian.html

I am most likely missing something. Please let me know if you have a tip.



Please do the following: Edit tests/loop_c_ev2/src/Makefile add “-lpthread” to the LIBRARIES list LIBRARIES = -lev2citrusleaf -levent -lssl -lrt -lcrypto -lpthread
