Having a sanctioned way to compile targeting a version of the kernel that is installed — but not running — would be helpful in many circumstances. — Stephen > On Jan 17, 2020, at 11:58 AM, Ryan Novosielski wrote: > > Yeah, support got back to me with a similar response earlier today that I’d

Yeah, support got back to me with a similar response earlier today that I’d not seen yet that made it a lot clearer what I “did wrong". This would appear to be the cause in my case: [root@master config]# diff env.mcr env.mcr-1062.9.1 4,5c4,5 < #define LINUX_KERNEL_VERSION 31000999 < #define

Hi Ryan,   Some interesting IBM-internal communication overnight. The problems seems related to a change made to LINUX_KERNEL_VERSION_VERBOSE to handle the additional digit in the kernel numbering (3.10.0-1000+) . The GPL layer expected LINUX_KERNEL_VERSION_VERBOSE to have that extra digit, and
