in graphics mode : font not loaded in c++

hi to all, I've centos7.5 in VM. i installed SDL_bgi in my system for graphics programming. I coded following in IDE.

Code:

---

#include <graphics.h>
#include <iostream>

int main(int argc, char ** argv)
{
    int gd = DETECT, gm;

    initgraph(&gd, &gm, NULL);

    circle(50, 50, 30);

    delay(500000);
    closegraph();
    return 0;
}

---

output in C::B is fine displays a circle.

but when i ran in command prompt shows this error :-

Code:

---

[rahul@centos7client Release]$ ./cbs
The font has not been loaded!

---

how to solve this. pleae help.

That's a bit weird. The version of SDL_bgi that I found seems to have a font hardcoded in... although that is an SDL error. You might need to install the library sdl2-ttf (the centos package name appears to be SDL_ttf-devel which should install the library as well. I guess so anyway, I don't use Centos so I'm just guessing :D)
