NI-KAL Beta 1.10 - Question

[anshuljain]

Shawn,

I noticed the beta release 1.10 for NI-KAL, many thanks! I also read the modversions support for Opensuse....now is this meant for 11.1? I would definetly want to try this on Opensuse 11.1 and report back on any issues. Any other distro that you want this version of NI-KAL to test it on?

I get this error with on Fedora (with F11 kernels from rawhide, and F10 everything else):

Man you're fast!  I didn't even get a chance to post an announcement yet .

Ah, and you read the README...  Those steps for installing on openSUSE should be valid for 10.3, 11.0, and will be needed for 11.1.  You may have also noticed that the README still only claims official support for openSUSE 10.3 and 11.0.  That is because if you just follow those steps and then install something like NI-DAQmx on openSUSE 11.1 it still won't work.  With the NI-KAL 1.10 beta you must run updateNIDrivers after installing all NI Software if you are using openSUSE 11.1, and then it should work.

Testing openSUSE 11.1 (after running updateNIDrivers), would be greatly appreciated.  Besides that feel free to test any distribution you want.  I guess I should also warn that this NI-KAL 1.10 beta also won't work on any Linux distribution that has kernel 2.6.29 or greater so there really isn't any point in testing that because I already know it won't work.

OK, it chokes on F11 because of the init_mm issue. Is there a workaround for this that does not involve recompiling the kernel?

You guys really are fast!

Doesn't F10 still have 2.6.27?  I wouldn't expect it to fail if it does.

Hmm, I actually didn't know about these I'll have to take a look.

WARNING: "init_mm" [/usr/local/natinst/nikal/src/objects/nikal.ko] undefined!

I would expect this on 2.6.29 and newer, and I'm guessing that even though this is just a warning it is also what caused this:

Installing NI-KAL (nikal): Starting NI-KAL failed!

This should be because init_mm is no longer exported, but can you run "dmesg" to see the error message on why nikal.ko failed to load?

Thanks,

Not yet, and unfortunately it is a difficult problem to solve.

From some googling... can you replace init_mm with current->mm->pgd?

Hello,

I have tested nikal 1.10 on Open SuSe 11.1 and gets exactly the same error:

Thanks for testing!  Take a look at the Installation Issues section of the README file.  Specifically the steps to to prepare your kernel source for openSUSE.  You need to run step 3.  Then running updateNIDrivers should fix the problem.

Let me know if you have any further issues.  Looks like I should probably fix those compiler warnings too.

Hello,

Thanks for your answer, I have been able of building the modules nikal and nipalk, I missed the step you pointed. But now I get the folowing errors.

This looks like the modules do not work on 64bits OS.
