Subject: [PATCH 1/3] selftests/bpf: Makefile: add includes to fix broken test build
Date: Thu, 26 Apr 2018 10:31:09 +0200 [thread overview]
Message-ID: <20180426083107.GA13908@vm4> (raw)
several bpf tests fail to build with clang 7.0.0:
...
In file included from ../../../include/uapi/linux/bpf.h:11:
In file included from ./include/uapi/linux/types.h:5:
/usr/include/asm-generic/int-ll64.h:11:10: fatal error: 'asm/bitsperlong.h' file not found
/usr/include/asm-generic/int-ll64.h is from outside the kernel repo,
probably a good idea to repoint to -I$(ROOT)/include/uapi.
asm/bitsperlong.h is architecture-specific, cater for this with an
architecture-specific include -I$(ROOT)/$(ARCH)/include/uapi.
Re-building now yields:
../../../../include/uapi/linux/stddef.h:2:10: fatal error: 'linux/compiler_types.h' file not found
Fix this with -I$(ROOT)/include
