Problem using a <curses.h> header function

  • 772

I have this C code:

#include <curses.h>
int main(){
    initscr();
    move(10,30);
    printf("Hola");
    return 0;
}

I get this error:

main.C:(.text+0xf): undefined refernce to 'initfscr'
main.C:(.text+0x23): undefined refernce to 'move'

The command gccis:

gcc main.c -o main.exe

I have installed it using the MinGW installer. How can I solve this problem?.
I've tried uninstalling and reinstalling it but it doesn't work.

Update:

I have also linked my project with the frag of -lncursesand I get the same problems:

gcc -lncurses main.c -o main.exe
c

    When you import certain libraries in C you have to specify a specific flag to indicate to the compiler that you are making use of other libraries ( linker ), in the case of curses.h you have to specify that you are using that library with the flag -lncursesa Sometimes it appears as -lcursessuch that your build command should be

    gcc main.c -o main.exe -lncurses
gcc main.c -o main.exe -lcurses

    And for a library with debugging is used -lncurses_gor -lcurses_gbe the case
