Hi everyone,

I'm new user of MariaDB, and I install it on Centos 6.8 64bit.

I install it using yum utility , according instruction on MariaDB site: https://mariadb.com/kb/en/mariadb/yum/.

yum install MariaDB-server MariaDB-client finished without any problem.

I can use mysql client to connect to databases without any problems.

Then I try to compile some of my applications.

To find out what library to use and where include files are I use mysql_config and mariadb_config.

mysql_config output:

[root@xms tests]# mysql_config

Usage: /usr/bin/mysql_config [OPTIONS]

Options:

--cflags [-I/usr/include/mysql ]

--include [-I/usr/include/mysql]

--libs [-L/usr/lib64 -lmariadb]

--libs_r [-L/usr/lib64 -lmariadb]

--plugindir [/usr/lib64/mysql/plugin]

--socket [/var/lib/mysql/mysql.sock]

--port [0]

--version [10.2.6]

--libmysqld-libs [-L/usr/lib64 -lmysqld -lpthread -lz -lm -lrt -ldl -lssl -lcrypto -lcrypt -laio]

--variable=VAR VAR is one of:

pkgincludedir [/usr/include/mysql]

pkglibdir [/usr/lib64]

plugindir [/usr/lib64/mysql/plugin]

[root@xms tests]#

And mariadb_config returns:

[root@xms tests]# mariadb_config

Get compiler flags for using the MariaDB Connector/C.

Usage: mariadb_config [OPTIONS]

--cflags [-I/usr/include/mysql -I/usr/include/mysql/mysql]

--include [-I/usr/include/mysql -I/usr/include/mysql/mysql]

--libs [-L/usr/lib64/ -lmariadb -lpthread -ldl -lm -lssl -lcrypto]

--libs_r [-L/usr/lib64/ -lmariadb -lpthread -ldl -lm -lssl -lcrypto]

--libs_sys [-lpthread -ldl -lm -lssl -lcrypto]

--version [10.2.5]

--socket [/var/lib/mysql/mysql.sock]

--port [3306]

--plugindir [/usr/lib64/mysql/plugin]

--tlsinfo [OpenSSL 1.0.1e]

[root@xms tests]#

First question is why these two outputs are different?

I wrote Makefile and use -I and -L like this in mysql_config.

gcc compiler finish with error that there is no mariadb library.

What I have missed?

Where is libmariadb located?
