Subject: [PATCH bpf-next v2 3/4] tools: bpf: account for generated feature/ and libbpf/ directories
Date: Fri, 30 Aug 2019 12:00:39 +0100 [thread overview]
Message-ID: <20190830110040.31257-4-quentin.monnet@netronome.com> (raw)
In-Reply-To: <20190830110040.31257-1-quentin.monnet@netronome.com>
When building "tools/bpf" from the top of the Linux repository, the
build system passes a value for the $(OUTPUT) Makefile variable to
tools/bpf/Makefile and tools/bpf/bpftool/Makefile, which results in
generating "libbpf/" (for bpftool) and "feature/" (bpf and bpftool)
directories inside the tree.
This commit adds such directories to the relevant .gitignore files, and
edits the Makefiles to ensure they are removed on "make clean". The use
of "rm" is also made consistent throughout those Makefiles (relies on
the $(RM) variable, use "--" to prevent interpreting
$(OUTPUT)/$(DESTDIR) as options.
v2:
- New patch.
