Installing Ni-KAL on Redhat 3 with 4G ram

[Micho]

Hello I've downloaded Ni-Visa  4.1 and Ni-488.2 v2.5 for redhat 3. I've burned the ISO images to CD and ran the INSTALL script for both disk. After rebooting I still can not launch any of the utilities such as

gpibexplorer without getting an abort message. Running my C++ program results in a core dump.

Are there any known issues with using Visa on RH3 or any instructions that deviate from the readme file?

Note, I've installed the latest NiVisa and 4882 software on a Redhat 5 box and all is working fine including my C++ program.

This is the only warning/error in the install log file:

May  4 12:12:53 <deleted hostname> kernel: [nikal] More than 4GB of addressable memory detected.

May  4 12:12:53 <deleted hostname> kernel: [nikal] This configuration is not supported.  Check the release notes for more information.

Hi Micho,

Add memmap=60G$0x100000000 to your kernel commandline while booting.

This works around a limitation of nikal.

Hi Martin,

I didn't try the memmap option yet as I'm trying to understand the values that you are suggesting to set it to. But what I did try was setting mem=4096M and mem=2048M. I'm using RHEL 3 with 4gig of ram.

When mem=4096M I still get the over 4G of memory error. When mem=2048M the installation and my c++ program execute fine until I reboot and let the default 4G of ram load, then my program breaks and gpibtsw reports the software is not installed correctly. I am curious to know if I will be seeing the same results by settings memmap=60G$0x100000000 at the command line during boot up?

I have applications running that require 4G of ram so I can't make permenate kernal changes that restrict me to using less than 4G.

Thanks.
