I choose grsecurity-3.0-3.14.27-201501042018.patch and linux-3.14.27 kernel
I choose several pax patch, alse have this problem

I am running into the same issue with powerpc.

I am trying to cross-compile the 3.14.49 kernel with the 3.14.49 grsecurity patches. ( grsecurity-3.1-3.14.49-201508032312.patch )

The base 3.14.49 kernel cross-compiles without error. It also boots on my target hardware.

After I applied the grsecurity patches, I get the error about a missing "compiler.h"

I checked in the before-patch kernel code, and I found these compiler.h files:

Code: Select all

> find . -name compiler.h
./include/linux/compiler.h
./arch/mips/include/asm/compiler.h
./arch/arm64/include/asm/compiler.h
./arch/alpha/include/asm/compiler.h
./arch/alpha/include/uapi/asm/compiler.h
./arch/arm/include/asm/compiler.h
./tools/include/linux/compiler.h
./tools/lib/lockdep/uinclude/linux/compiler.h


There is no compiler.h under arch/powerpc in the base kernel from kernel.org.

check arch/powerpc/boot/Makefile:cmd_copy_zliblinuxheader, it copies/patches kernel headers into the build dir and will have to be fixed to somehow produce a definition for (or get rid of) __intentional_overflow which is used in zlib.h.
