undefined reference to /usr/local/lib/libSDL2_ttf.so undefined reference to `SDL_RWseek

hi to all, I've centos7.5 in VM. I am trying to compile to SDL2 program. but having following problem :-
Code:/usr/local/lib/libSDL2_ttf.so||undefined reference to `SDL_RWseek'|
/usr/local/lib/libSDL2_ttf.so||undefined reference to `SDL_RWclose'|
/usr/local/lib/libSDL2_ttf.so||undefined reference to `SDL_RWtell'|
/usr/local/lib/libSDL2_ttf.so||undefined reference to `SDL_RWsize'|
/usr/local/lib/libSDL2_ttf.so||undefined reference to `SDL_RWread'|
||error: ld returned 1 exit status|mine source code is :-

}how to remove those errors
