can't run updateNIDrivers 2.6.27.21-170.2.56.fc10.x86_64

Hi,

I'm having trouble running updateNIDrivers with the latest Fedora 10 kernel. updateNIDrivers falls back to the previous kernel, without explaining why. Here's the output:

[root@pekkala NIKAL-1.9]# uname -a

You can now use your NI products when you boot into kernel 2.6.27.21-170.2.56.fc10.x86_64.

(Running against the earlier kernel generates the same gcc warning, but it works.)

Running LabView causes a crash, of course:

[mjclab@pekkala ~]$ labview /fileserver/mjcfiles/op1b/labview/AVTTCAL.llb
libnipalu.so failed to initialize
Perhaps you need to run updateNIDrivers
Aborted

It isn't a "MODVERSION" issue:

[root@pekkala ~]# grep MODVERSIONS /boot/config-2.6.27.*
/boot/config-2.6.27.15-170.2.24.fc10.x86_64:# CONFIG_MODVERSIONS is not set
/boot/config-2.6.27.19-170.2.35.fc10.x86_64:# CONFIG_MODVERSIONS is not set
/boot/config-2.6.27.21-170.2.56.fc10.x86_64:# CONFIG_MODVERSIONS is not set

Any suggestions?

The /boot/config* files are exactly the same, actually, except for version info.

Hi Mike,

I'd need to take a closer look at the updateNIDrivers script to figure out why it says it is configured for your older kernel.  It may simply be because NI-KAL is erroring out with your current kernel, so it falls back to the old one.  I'm guessing you really just want it to work with your current kernel.

Actually this error means exactly what it says.  The version of your C compiler, gcc 4.4.0, is different from the version of the C compiler used to build the latest kernel, gcc 4.3.2.  Since NI-KAL is a small C kernel module, it should be compiled with the same version of gcc as your kernel.  The only way I know to fix this is upgrade/downgrade your kernel or gcc versions until they match.  So if you are running the latest Fedora 10 kernel, then you may need to downgrade gcc to version 4.3.2.  You can always file a bug report to Fedora since these versions should always match or you can't build external kernel modules.
