can't connect to mariadb properly

I'm now trying to implement a server using c++, I try to save the information of the users into database, but I came across some problem while connecting to the database. I can't build my program because of the following errors generated by code blocks

    -------------- Build: Debug in server (compiler: GNU GCC Compiler)---------------

    mingw32-g++.exe -Wall -fexceptions -g -lpthread -lmysql -I"D:\Program Files\MariaDB 10.1\include\mysql" -c D:\Projects\server\main.cpp -o obj\Debug\main.o
    mingw32-g++.exe -L"D:\Program Files\MariaDB 10.1\lib" -o bin\Debug\server.exe obj\Debug\main.o   "D:\Program Files (x86)\CodeBlocks\MinGW\lib\libwinpthread.a" "D:\Program Files (x86)\CodeBlocks\MinGW\lib\libws2_32.a"
    obj\Debug\main.o: In function `main':
    D:/Projects/server/main.cpp:13: undefined reference to `mysql_init@4'
    D:/Projects/server/main.cpp:14: undefined reference to `mysql_real_connect@32'
    collect2.exe: error: ld returned 1 exit status
    Process terminated with status 1 (0 minute(s), 2 second(s))
    3 error(s), 3 warning(s) (0 minute(s), 2 second(s))

I downloaded MariaDB Connector/ODBC 2.0.10 Stable from its official website and I've tried many different solutions that I found on the Internet, but it still doesn't work. Can anybody help me solve this? Any reply will be appreciated.

GNU linker is sensitive to option order. If you are using libmysql in main, option -lmysql shall go after main.o

UPD: I noticed you even haven't libs in second linking string. In first string it is useless, add to second, where actual linking takes place.
