Compiler can't find sstream?

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:\mingw\bin../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?

<graphics.h> is operating system specific. You might consider libsdl or gtk (or in C++ Qt...) since they all probably run on more operating systems. – Kreutzer

@BasileStarynkevitch : Thanks! As a beginner, which one should I begin with, and also which one would be more beneficial in the long run? – Bellebelleek

It depends what you want to do with it. My suggestion actually would be to install Linux (most distributions have libsdl,gtk,Qt already) on your machine. Don't forget to enable all warnings and debug info in your compiler (gcc -Wall -Wextra -g) and learn how to use the debugger (gdb) – Kreutzer

The interesting thing about Linux is that it is mostly (or fully, if you are careful) made of free software whose source code you can study and improve. You'll learn a lot. – Kreutzer

@BasileStarynkevitch : Thanks a lot! Yeah, as a computer science student I have got to learn all those things you mentioned. I already have Ubuntu along with Windows. I'll try my best :) – Bellebelleek

Take the habit of studying the source code of some free software you are using (perhaps start with your shell, or /bin/ls) ; you'll learn a lot – Kreutzer

Does this answer your question? How I can get and use the header file <graphics.h> in my C++ program? – Ultima

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.

Notice that DirectX is Windows specific. – Kreutzer

Thanks! So I can't use graphics.h (I have a gcc compiler). I tried searching for how to use OpenGL / DirectX, but there were two different types of solutions - either use them directly (using some <gl/glu.h>) header files or download glut/ freeglut / flgw etc. and use those header files (like <glut.h>). Which one would be easier, considering I don't know the basics of any graphic programming, and wish to use them only for my C/C++ programs? – Bellebelleek

@BasileStarynkevitch : Yes, which has now left me wondering if I should use it or OpenGL. Is it true that programs made using OpenGL are not much effective on a Windows Platform? I have both Windows and Ubuntu. – Bellebelleek

The main issues with OpenGL on Windows is that by default Windows only comes with a software-only OpenGL 1.x API. To have hardware support or any newer version of OpenGL requires installing a 3rd-party ICD driver. That said, many driver packages from AMD/ATI, NVidia, and Intel come with these ICDs. – Rhotacism

If you try to compile the source code with including “graphics.h” in code::blocks IDE you have to setup winBGIm library.

• Download WinBGIm from http://winbgim.codecutter.org/ or use (direct link)
• Extract it.
• Open graphics.h, go to line 302 change int right=0 to int top=0
• Copy graphics.h and winbgim.h files in include folder of your compiler directory.
• Copy libbgi.a to lib folder of your compiler directory
• In code::blocks open Settings >> Compiler and debugger >> linker settings
• Click Add button in link libraries part, browse and select libbgi.a file
• In right part (ie. other linker options) paste commands
  -lbgi -lgdi32 -lcomdlg32 -luuid -loleaut32 -lole32
• Click Ok

Thanks! What does changing int right=0 to int top=0 do? – Bubaline

Answer 3

When you're compiling a C source code having graphics.h header file, you'll need to change the file extension to .cpp. Without doing that, you'll get “fatal error: sstream : no such file directory” error.

So, simply change the .c extension to .cpp. Here's a step-by-step procedure to compiling graphics.h source code if you're using Code::Blocks to run the code.

But still I am unable to run simple programs. When I execute, it says "program stops working". – Bellebelleek

Answer 4

The sstream error occurs only when you are compiling using gcc not g++ , try using g++ or converting the program to c++ , as far as i know ( since i'm new to this language but i've faced this error before ) so goodluck with that

Answer 5

If top answer doesn't work, and you are getting:

• error: narrowing conversion of 'x' from 'int' to 'short unsigned int'

• your graphics window just doesn't appear

  following this tutorial and using the bug fixed headers/libraries (winBGIm(bug-free).rar) in the provided winBGIm source link, worked for me in Windows 10.

Mirror to winBGIm(bug-free_.rar)

compiling with: g++ example.cpp -Wall -m32 -std=c++11 -pedantic -g -lbgi -lgdi32 -lcomdlg32 -luuid -loleaut32 -lole32 -o example.exe

Answer 6

this process is abosulitly right. doing this process step by step your code is compile and execute. change the extension of your program to .c to .cpp step1. https://youtu.be/CHFyEnlMnxg through this video follow all step.
