We have kamailio server v. 5.3.1 with db_mysql.so built with our old mysql
library 5.1.41. Now I'm trying to build it with libperconaclient20. I've
tried many variants of build configuration, but every time I got errors
when kamailio stops or starts, such:

Is there some specific way to build kamailio with percona?
