Dosbox-x works differently on different machines

(1/2) > >>

Hello, that's about the copy of Dosbox-x available on App, so I think it's correct to ask you first.


# Scenario 1:

Dosbox-x works pretty fine on Core installed on VirtualBox, hosted in turn by Slackware 15_64, on condition that Core is started from scratch.
If something else has been loaded before, Dosbox-x starts but the software I mean to use on it doesn't start.


# Scenario 2:

The same version of Dosbox-x starts but crashes on any configure attempt on Core installed on a Pentium 2 laptop.
Errors like "Illegal instruction" or "...Int15..." show.



I haven't been able to create any config file for none of the copies of Dosbox-x.
Trying to do that via its Configuration Tool, on the Vbox copy no file is created neither in the user's homedir, while the P2 copy crashes straightly.


On both copies of Dosbox-x I've installed Autocad R12 for DOS. That's the program I'd like to use.
If it starts, on the Pentium 2 the mouse pointer moves jerkily when activated as Autocad pointer.
As stated, I'm unable to do a config file to transfer from the lucky machine to the desperate one.


So I've tried to build a more recent version of Dosbox-x but I've realized that it's not like building Gimp.

Any suggestions or references would be very appreciated.

Many thanks

Thank you so much.

I continue to get the following error:

/usr/local/bin/ld: warning: creating DT_TEXTREL in a PIE
collect2: error: ld returned 1 exit status

I had tried to add -no-pie and -fno-pie but unsuccessfully. Not sure I did it correctly.

Hi t18
You might want to try something besides dosbox. Dosbox seems
to be mostly geared towards games. I fired up dosbox and I noticed
it consumed about 30% of the CPU time. And it wasn't even running
any programs, just a command prompt with a blinking cursor. One
of dosboxes functions is to slow things down so games don't execute
too quickly, something you don't need. It also provides other support
functions for games (sound, joystick, etc.) which you also don't need.

I'm wondering if it might be simpler to install FreeDos to a separate
partition, boot that and run Autocad R12 for DOS on that.

Or, maybe spin up a copy of FreeDos under VirtualBox or Qemu and
run Autocad R12 for DOS from there.

Hi Rich,

I'm speaking about Dosbox-x, not Dosbox. I've chosen it because of its smaller package size, assuming it would require a smaller amount of RAM, hopefully.

Other than running games and programs, Dosbox-x allows us to install DOS and all the DOS-based versions of Windows, i.e. up to Win ME.
But that is possible having the necessary amount of RAM, while my aim is just to run an old DOS version of Autocad (i.e. requiring a low amount of RAM) on Linux.
That's because a Linux version of Autocad doesn't exist and my laptop is 160 Mb RAM only.

The FreeDOS option would be interesting if it's possible to install it on Linux straightly, but if I need Virtualbox what would it be the difference between
"Core + Dosbox-x + Autocad"
against
"Core + Virtualbox + FreeDos + Autocad"
in term of RAM requirement?

Compiling Dosbox-x on Core I got the "PIE" error. Any way to fix it?
