how to install graphics library in ubuntu 19,04

Wojciech Guzinski - Hello

Per: https://packages.ubuntu.com/search?searchon=contents&keywords=libesd0-dev&mode=filename&suite=disco&arch=any
That package does not exist in disco.
Typo ?
Where do you get the directive that the package is required ?

-my bit to try and help-

I found information on internet, but it was for previous ubuntu versions. I could not found instruction for ubuntu 19.04
If anybody knows how to do it please help.

"If anybody knows how to do it please help."
What exactly do you want to do?

Do you want to play around with the turbo c graphics API on Linux using SDL?
This is outdated, but still may be working with a few tricks, see
https://askubuntu.com/questions/525051/how-do-i-use-graphics-h-in-ubuntu
That askubuntu document describes also other and more current graphics libraries, e.g. OpenGL (via GLUT) and libxbgi,

I'm working with gnu g++in ubuntu 19.04 and want include graphics

In https://askubuntu.com/questions/525051/how-do-i-use-graphics-h-in-ubuntu I foun:
From Ubuntu 18.04 guile-2.0 works and libesd0-dev is deprecated.
Then in package to be installed libesd0-dev still exists, so I remove it and installed packaged.
In next lines I found:

Now extract the downloaded libgraph-1.0.2.tar.gz file.
Go to the extracted folder and run the following command:

Question: where is the libgraph-1.0.2.tar.gz file and where is extracted folder?

Read the text in the link that I gave.
At the beginning of https://askubuntu.com/a/525052 it says "You can download it from here."

I did your steps (with removed libesd0-dev) but later on I've got fatal error message:
guile-libgraph.c:25:10: fatal error: libguile.h: No such file or directory
 #include <libguile.h>
          ^~~~~~~~~~~~
Note: I have ubuntu 19.04

Please help 😊

Thanks. Wojtek

Run time problem:
[xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
demo: ../../src/xcb_io.c:263: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed.
Regardless of time of delay set graphics window is closed after 10s

Last problem "regardless of time of delay ...." resolved.
Still run time error message is displayed.

Try running your program with

LIBGL_DRI3_DISABLE=true run_the_program

(and replace "run_the_program" with whatever command you used before)

Source: Bug #1754084

I just make the program:
 g++ demo.c -l graph -o demo
then run program:
 demo
Result (graphics) was as expected, just after completion error message was issued.
I don't know how to apply your advice ☹

You received this question notification because you asked the question.

You run the program with "demo", so my recommendation is to try "LIBGL_DRI3_DISABLE=true demo"

It didn't help, so I'm ignoring message:
    demo 2>err
or
    demo 2>/dev/null
