[OpenAFS-devel] dkms install Error

[Cheyenne Wills]

Can you check to see if the current compiler version matches the
version that the kernel was built with?  If they are different, the
builds kernel modules can fail.  The specific error you are seeing is
within the configure step of the OpenAFS build process where configure
is trying to determine how to pass compiler flags to the Linux build
process.

The .config file for the Linux kernel contains the compiler version
Compare the the CONFIG_GCC_VERSION_TEXT and CONFIG_GCC_VERSION values
with the output of a gcc --version to see if they are different.

If they do match up, then a deeper dive into the logs from the build
will be needed, and I can give a hand in looking through those.

There are some patches to the configure tests that report the compiler
version that was used in the kernel build.  They are in master
but haven't been pulled up into the stable release (due to the scope
and size of the changes).
