Subject: [PATCH HID for-next v1 2/9] selftests: hid: allow to compile hid_bpf with LLVM
Date: Fri, 6 Jan 2023 11:23:25 +0100 [thread overview]
Message-ID: <20230106102332.1019632-3-benjamin.tissoires@redhat.com> (raw)
In-Reply-To: <20230106102332.1019632-1-benjamin.tissoires@redhat.com>
clang doesn't like to compile a source to the final binary directly:
clang-14: error: cannot specify -o when generating multiple output files
So split the final rule in 2, and ensure we compile all dependencies
before.
