Dosemu and kubuntu 8.04

[VictorWarner]

I have just download kubuntu today and installed dosemu available "Add/remove programs"

When I try to run it I get the following error message in console:

LOWRAM mmap: Invalid argument
Segmentation fault (core dumped)

Is there a solution to this? I have limited technical understanding of Linux so I do not where to go fix this.

Re: Dosemu and kubuntu 8.04

The error implies that you don't have enough installed RAM. How much RAM do you have in your PC?

Thank you for the reply. I have 2 gigabytes.

Well, that's more than enough. Hmm.

The dosemu HOWTO (dated, but ...)

The dosemu HOWTO (more recent)

Re: Dosemu and kubuntu 8.04

You have installed Kubuntu on your hard drive? How much space did you allocate for swap? Or you are running the Live CD?

2 GB is way plenty of RAM. I've never installed that particular package, but a segmentation fault does typically relate to memory shortage or memory utilization issues.

Thank you for all the replies.

Eventually I found the solution on a Wine forum and from the mailing list at www.dosemu.org:

The temporary solution (lost on each reboot) is to type

sudo sysctl -w vm.mmap_min_addr=0

or

echo 0 > /proc/sys/vm/mmap_min_addr

in console. The permanent solution is

Change

* vm.mmap_min_addr = 65536
to:

* vm.mmap_min_addr = 0

in /etc/sysctl.conf (this file needs to be edited with root permissions, or in console with sudo gedit or sudo kate etc)
