Linux kernel error insmod: ERROR: could not insert module ./spcm.ko: Invalid module format

If trying to install the Spectrum kernel driver on a Linux system you get the message:

insmod: ERROR: could not insert module ./spcm.ko: Invalid module format

This is caused due to a mismatch in the exact kernel version of the Spectrum driver and your installed Linux system. Unfortunately Linux is very critical concerning the kernel module version and it refuses to load kernel drivers that do not match 100%. To see which kernel driver versions are supported natively please have a look at the this list of supported kernel versions.

To see how to compile your own kernel driver module for your particular system please follow this how-to description.
