Did you read and follow the instructions in both the README and INSTALL files that are included in the file you downloaded?? You've had numerous threads where you've either not responded at all, haven't followed the advice given, or have shown little to no effort of your own first. Again, read the "Question Guidelines".

yes i've read all in Install and readme files, but found nothing regarding this error.

...because you didn't follow the instructions in those files. There are a specific list of things you need to install first. If you read and follow the instructions, you won't get errors.

No issues here, CentOS 7 :

Code:

# yum install SDL-devel.x86_64 SDL_image-devel.x86_64 guile-devel.x86_64
                         // The SDL_image packages are in the EPEL repo
$ tar xvf libgraph-1.0.2.tar.gz
$ cd libgraph-1.0.2/
$ ./configure --prefix=/usr --libdir=/usr/lib64 && make
# make install

Result = libgraph-1.0.2-1.el7.x86_64.rpm

Download ... and install :

Code:

# yum install Downloads/libgraph-1.0.2-1.el7.x86_64.rpm

Yep...those SDL packages are explicitly mentioned in the README, which the OP said that they read.

Code:

**** FROM THE TOP PART OF THE README FILE ****
What do I need ?
----------------
        You need to have the following installed : 
                SDL-x.x.x.rpm                           -- the main SDL library
                SDL-devel-x.x.x.rpm             -- the developer package
                SDL_image-x.x.x.rpm             -- image library for fonts
                SDL_image-devel-x.x.x.rpm       -- image library developer

Without the SDL packages, you do get the aforementioned error.

thanks a lot, finally i installed libgraph on my centos7.5.
i install above rpm and then reinstalling libgraph, it happened
i ran this program i in codeblocks :-

Code:

#include<stdio.h> 
#include<stdlib.h> 
#include<graphics.h> 
int main() 
{ 
    int gd = DETECT, gm; 
    initgraph(&gd, &gm, NULL); 
  
    circle(50, 50, 30); 
  
    delay(500000); 
    closegraph(); 
    return 0; 
}

and i linked "graph", in search "/usr/local/include" and in linker "/usr/local/lib"
and it ran fine.

problem of installing of libgraph is solved but now again one problem is here :-
when i run program in codeblocks ide it runs fine but when i run its executable file in terminal it shows following error :

Code:

[rahul@centos7client Debug]$ ./graphincpp 
The font has not been loaded!

Right; did you think about what you installed and how???

AGAIN: you need to **READ AND FOLLOW** the instructions on installing libgraph, and remove the package you installed. knudfl followed the instructions and generated a package....which was based on the configure program for HIS SYSTEM. The paths/fonts/whatever you're using on YOUR system are different, and because you didn't install the correct SDL packages/libraries, and configure/link against them, you have an error. Since you've been using Codeblocks for at least five years now, you know that it does linking and other things to paths for you, based on how you configure it.
