Skip input buffer in c? - c

Question

I am making a small console game and want to allow instant input and output for the player so that they don't have to hit enter after each move. I understand there are already a few solutions that can be found online, most prominently ncurses (I'm on linux), but I have not been able to get anything to work. When I input the code below, I get the message:
main.cpp:(.text+0x39c): undefined reference to `initscr'
main.cpp:(.text+0x3a3): undefined reference to `stdscr'
main.cpp:(.text+0x3ac): undefined reference to `wgetch'
main.cpp:(.text+0x3b4): undefined reference to `endwin'
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I understand skipping the input buffer is not standard in C, but any ways around this would be greatly appreciated. I can make the code work by just using key = getchar(); but as aforementioned, I want to skip the necessary enter key.
void move(int key){
initscr();
key = getch();
switch(key){
case 'w': if (playery > 1){y--;}
break;
case 's': if (playery < height - 1){y++;}
break;
case 'a': if(playerx > 1){x--;}
break;
case 'd': if(playerx < width - 1){x++;}
break;
default: grid[x][y] = 'x';
break;
}
endwin();
}

You need to link with ncurses to make it work. When you include curses.h or ncurses.h, it includes just the definitions. The actual code is separated, so you have to tell your compiler to add the code to your program.
Compiling with clang
Use this when compiling C++:
clang++ main.cpp -lncurses
Use this when compiling C:
clang main.c -lncurses
Never use clang with C++ or clang++ with C. It creates a huge mess.
Compiling with GNU/gcc
Use this when compiling C++:
g++ main.cpp -lncurses
Use this when compiling C:
gcc main.c -lncurses
Again, do not interchange those.
You say you use C, but you have main.cpp, which implies you are using C++. Rename your file to main.c or edit your question.
As noted in comments, ncurses already has a function named move. You should rename your function.
