c - Error due to #include<graphics.h>

Question

I am trying to compile a program which includes the graphics.h header file for C. I have added the graphics.h and winbgim.h header files in the include folder and also libbgi.a to lib folder.

Just for testing, I made a simple hello world program and included the graphics.h header file.

But on compiling I got the following error:

In file included from firstc.c:2:0: c:mingwin../lib/gcc/mingw32/4.7.1/../../../../include/graphics.h:30:59: fatal error: sstream: No such file or directory compilation terminated.

I tried to search in other forums as well, where the same question had been asked, but could not get an answer.

Another question, I came across other graphic options for C and C++ like openGL and DirectX. Should I learn these instead of graphics.h?

Answer 1

graphics.h is a non-standard header. Most likely it refers to the old BGI graphics library of the Turbo C DOS compiler. It will only work on that particular compiler. And of course DOS is a completely obsolete OS nowadays.

If you are interested in 3D graphics programming, then OpenGL and/or DirectX are indeed better, modern alternatives, supported by many compilers.
