Description Clemens Noss 2012-02-05 18:56:28 UTC 
One of

export GCC_INCLUDE_DIR="${KERNEL_DIR}/arch/x86/include/generated/"
export C_INCLUDE_PATH="${KERNEL_DIR}/arch/x86/include/generated/"

before linux-mod_src_compile works around this.

Tested with Linux 3.3-rc commit 23783f817bceedd6d4e549385e3f400ea64059e5 and nvidia-drivers-290.10-rc1

Since Linux commit 303395ac3bf3e2cb488435537d416bc840438fcb, unistd_{32,64}.h are autogenerated and placed in arch/x86/include/generated/asm/. I don't know how they are supposed to be found there. A "git grep generated/" shows a lot of includes.

A "git grep /generated" shows at least one "-Iarch/$(hdr-arch)/include/generated". I can only tell that this may or may not be a kernel bug, or an eclass bug, or an nvidia upstream bug.

We don't support RC kernels. Never have and never will.
