How to install NI-VISA 4.4.0 kernel modules under Gentoo ?

[Sak1s]

I am trying to install the Ni-Visa  but the modules fail to compile into my kernel.....

I am using  2.6.26  kernel Version.

Can somebody help me a bit ?

the installation output  is here:

Configuring for linux kernel version 2.6.26-gentoo-r1.

If this does not correspond to the location of the 2.6.26-gentoo-r1 headers,
then define KERNELHEADERS in your environment to point to the location
of the kernel headers, define KERNELTARGET as the version of the

modules compiles fine with kernels (gentoo-sources) :

• 2.6.24
• 2.6.25

Hello,

NI VISA 4.4 for Linux requires one of the following distributions : Mandriva 2008, Mandriva 2007, openSUSE 10.3, openSUSE 10.2, Red Hat Enterprise Linux Desktop, Red Hat Enterprise Linux WS 4. This info can be found in the NI VISA 4.4.0 readme file. I do not know why other kernals compile. I will try and find a work-around for you.

Hi,

It only works with kernel 2.6.22 and below.

[Shawn B.]

We just released NI-KAL 1.9 which should compile on kernels up to 2.6.27.  We also just created a new Linux Users community where we can post announcements of new releases, and everyone can create tutorials and content on the wiki-like interface.

It failed compiling on my 2.6.25 gentoo kernel. I've attached the system report as well.

Um, have you applied additional kernel patches to your kernel?  I just took a peek in on my gentoo system where I still have 2.6.25-gentoo-r6 hanging around and init_mm is still defined and exported in:

arch/x86/kernel/init_task.c

So unless you have applied a patch that unexports init_mm I'm not sure why it is failing.  P.S. your niSystemReport shows you are still using NI-KAL 1.8 instead of 1.9, but it shouldn't matter unless you want to run newer kernels.

Hi,

I'm using the default gentoo-sources. I have that file too and init_mm is defined  there:

struct mm_struct init_mm = INIT_MM(init_mm);

I'm not sure why it's complaining.

PS. is ni-kal updated for newer kernels as well?

[Shawn B.]

does your file have:

struct mm_struct init_mm = INIT_MM(init_mm);
EXPORT_UNUSED_SYMBOL(init_mm); /* will be removed in 2.6.26 */

It is actually the EXPORT_UNUSED_SYMBOL(init_mm) part that is important as that lets external kernel modules see the symbol.

NI-KAL 1.9 should compile against kernels 2.6.27 and older.

Hi,

Kernel headers are OK. I've found that the INSTALL script is not actually doing anything! Reading the INSTALL script it seems like I need to have either dpkg or rpm. is that correct?
