[RTnet-developers] RTnet Configuration Issue "Unsupported kernel version"

[James K. <jam...@gm...>]

When I try to configure RTnet using the autotools in a cross-compile
environment, I get the error "*** Unsupported kernel version".  What's
interesting is that I had this issue before, but by commenting out the
variable "CONFIG_RTNET_RTEXT_CLASSIC=y" in the configure.ac script it
could identify xenomai and the linux kernel.  This allowed me to build
valid kernel modules for arm-linux.  I committed all of the changes
into a local GIT repository and noted all of the environment variables
(PATH, CROSS_COMPILE, ARCH, etc) to ensure that I could get back to a
working build.

This most recent problem started after I rebuilt my development
machine kernel with Xenomai and RTnet so that I could properly test
the device.  Now that I go back to the cross-compile environment, I'm
running into the same problem as before, and I can verify that my
environment now to cross-compile RTnet is the same as before.

I've also tried re-running the "scripts/autogen.sh" with
"CONFIG_RTNET_RTEXT_CLASSIC=y" enabled again, but it still gives the
same error.

Finally, to my questions:  Why did I have to disable
CONFIG_RTNET_RTEXT_CLASSIC to make the build work in the first place?
Are there known issues with the autotool configuration for RTnet?  Any
ideas as to what could be going wrong?


Thanks,
