It is recommended to set the CC environment variable to the compiler that was used to compile the kernel. The compiler version check can be disabled by setting the IGNORE_CC_MISMATCH environment variable to "1". However, mixing compiler versions between the kernel and kernel modules can result in subtle bugs that are difficult to diagnose. *** Failed CC version check.
