Hello: I am attempting to re-compile a broken kernel module for the AltArch/Arm32 release. Currently I'm trying it against the current kernel, 4.9.75-204. In using "kernel-devel-4.9.75-204.el7.centos.armv7hl", and following the instructions for CentOS at : https://wiki.centos.org/HowTos/BuildingKernelModules, when I do a "make prepare", I am getting the error: make[1]: *** No rule to make target `arch/arm/tools/gen-mach-types', needed by `include/generated/mach-types.h'. Stop. make: *** [archprepare] Error 2 I've been searching for a fix for this but not sure what is missing here. If you have a solution please let me know. Thanks for your help on this. Chris
