This error indicates that either kgcc was used to compile the driver or a non-matching version of gcc was used.

Check for kgcc:

ls -l /usr/bin/\*cc

If kgcc is installed, a quick workaround would be to temporarily link it to gcc:

# cp /usr/bin/kgcc /usr/bin/kgcc.bak

# rm /usr/bin/kgcc

# ln -s /usr/bin/gcc /usr/bin/kgcc

Re-install the driver. Once the driver installation is complete, the kgcc.bak file can be moved back in place.

Matching gcc compiler:

Make sure your gcc compiler matches the kernel compiler:

# more /proc/version

# gcc --version

If not, you will need to upgrade your gcc compiler to match the kernel’s compiler verion.
