Compiling MGTEST

[progfrosty]

Hello

I'm trying to compile MGTEST for Linux (on Ubuntu 20) with fpc.

I notice that I get the following error when I run the example:

An unhandled exception occurred at $00000000004010D7:
EAccessViolation: Access violation
$00000000004010D7
$00000000004259CD
$00000000004258AB
$000000000040117E

Compiling with fpc -B -I../ MGTEST.PAS

All compiles OK.

Hi, @progfrosty !

Sorry for delay.

Please check frame buffer device settings - ./fbset -v
eg

# fbset -v
Linux Frame Buffer Device Configuration Version 2.1 (23/06/1999)
(C) Copyright 1995-1999 by Geert Uytterhoeven

Opening frame buffer device `/dev/fb0'
Using current video mode from `/dev/fb0'

mode "1280x720"
    geometry 1280 720 1280 720 16
    timings 0 0 0 0 0 0 0
    accel true
    rgba 5/11,6/5,5/0,0/0
endmode

Next, set constants fbdev , SCR_WIDTH, SCR_HEIGHT in file Linux/MGTEST.LPR
eg

const
  fbdev = '/dev/fb0';
  SCR_WIDTH = 1280;
  SCR_HEIGHT = 720;

Regards.
