 Description   

I am trying to compile the "hello world"-kind of program quoted below, but getting a bunch of "undefined reference" errors. With MySQL Connector/C 6.0.2 built on the same machine it compiles all right.

I presume it's something about configuration on my side; what worries me that i'm not getting the configuration problem with mysql

This works:

gcc conc23.c -I/data/bzr/mariadb-native-client/include -L/data/bzr/mariadb-native-client/libmariadb -lmariadbclient -ldl -lpthread -lz -lm -o conc23

While with MySQL Connector/C, this works:

gcc mini.c -I/home/elenst/mysql-connector-c-6.0.2/include -L/home/elenst/mysql-connector-c-6.0.2/libmysql -lmysqlclient -o mini
