---------------------

hi to all, I've centos 7.5 in VM. And i am trying to compile graphics program in C::B. I installed libgraph successfully and trying to build following program :-

Code Select Expand



//#include <graphics.h>
// graphics in linux enviornment
#include<cstdio>
#include<cstdlib>
#include<graphics.h>

//using namespace std;
int main()
{
    int gd = DETECT, gm;
    initgraph(&gd, &gm, NULL);

    circle(50, 50, 30);

    delay(5000);
    closegraph();
    return 0;
}

it gives following o/p :-

I installed "libgraph-1.0.2.tar.gz" with all of its dependencies.

sorry guys i attached "/usr/include/ligguile "  and after removing that from search directories. It ran but now having two errors:-
in terminal

Code Select Expand


[root@centos7client Debug]# ./grph
The font has not been loaded!
[root@centos7client Debug]#


and in IDE :-

Code Select Expand


[xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, aorry aboput that.
grph: xcb_io.c:263: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed

POST A FULL BUILD LOG!

Edit: Since, it now builds no log really needed; but, it is no longer a CB Problem.

I suggest getting rid of 15 year old "libgraph-1.0.2.tar.gz".

You might try reading this website rules.

You might try SDL BGI instead.
