<div class="markdown_content"><p>Compilation on RHEL 8.10 currently failing due to. I could temporary fixed this by:<br/> * Lowering the kernel version check to 4,18,0 in compat/include/linux/compiler_attributes.h (possible failing due to backport of fallthrough in RHEL kernel)<br/> * Default GCC option in RHEL 8.10 seems to be -Werror=incompatible-pointer-types. Added sibdir-cclags-y += -Wno-error=incompatible-pointer-types to drivers/gpib/Makefile</p></div>
