Installing the Software for Linux

The Acqiris Software is ready to install and run on Linux systems with any of the following:

RedHat Enterprise Linux Version 3 - Kernel Version 2.4.21-4.EL

RedHat Enterprise Linux Version 3 - Kernel Version 2.4.21-4.ELsmp,

Suse Linux 9.2 - Kernel version 2.6.8-24-smp,

Debian Sarge 3.1 2.6.8-3-686,

Debian 4.0 etch Kernel version 2.6.18-4-686,

Scientific Linux 4.4 Kernel version 2.6.9-11.EL)

The following tar files exist with the driver and library compiled with the

GNU gcc

version shown:

AcqirisLinux-3.1a-gcc-3.3.tar.gz - compiled under Suse 9.2 with GNU gcc 3.3.

AcqirisLinux-3.1a-gcc-3.4.tar.gz - compiled under SL 4.4 with GNU gcc 3.4.

AcqirisLinux-3.1a-gcc-4.1.tar.gz - compiled under Debian etch with GNU gcc 4.1.

The Kernel Driver source code is available for recompilation for users with other Linux systems.

The appropriate tar file should be copied to a local directory (e.g. your home directory) and then unpacked by using
the following command

tar xzf AcqirisLinux-3.1a-gcc-X.x.tar.gz

The resulting directory

AcqirisLinux

contains an install script

drv-install

and a graphical Demo program

demo/AcqirisDemo

Before installing the driver you have to put the correct version of the Kernel mode driver into acqirisPCI.o. Type

AcqirisLinux/lib/modules

and either

cp acqrsPCI.o[.n] acqrsPCI.o

(Linux kernel 2.4)

cp acqrsPCI.ko[.n] acqrsPCI.ko

(Linux kernel 2.6)

where [.n] is the running version of the Linux kernel. This can be obtained by running the command

uname

-r
