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.

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?

as for any other software on rpm-based distributions in the devel packages - i guess "MariaDB-devel" but looking at the terrible camel-case packagename anything is possible :-)

Hi, The MariaDB-devel RPM (for 10.2) seems to contain the following libraries on Fedora 25:

$ dnf repoquery -l MariaDB-devel|grep /usr/lib64 /usr/lib64/libmariadbclient.a /usr/lib64/libmysqld.a /usr/lib64/libmysqlservices.a /usr/lib64/mysql/libmysqlclient.so /usr/lib64/mysql/libmysqlclient_r.so /usr/lib64/pkgconfig/mariadb.pc /usr/lib64/mysql/libmysqlclient.so /usr/lib64/mysql/libmysqlclient_r.so /usr/lib64/pkgconfig/mariadb.pc /usr/lib64/libmysqlclient.a /usr/lib64/libmysqlclient_r.a /usr/lib64/libmysqld.a /usr/lib64/libmysqlservices.a

I think it'll work if you use -lmariadbclient instead of -lmariadb. As the mariadb_config gives the wrong paths, I recommend opening a bug report on jira.mariadb.org <https://jira.mariadb.org/projects/MDEV/>. Markus On 17/06/17 17:56, romeo kalebic wrote:

Hi everyone,

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 Copyright 2011-2015 MariaDB Corporation AB 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?
