Several Makefiles in tools/ need to define the host toolchain variables. Move their definition to tools/scripts/Makefile.include Acked-by: Jiri Olsa <jolsa@redhat.com> Acked-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Signed-off-by: Jean-Philippe Brucker <jean-philippe@linaro.org>
Cleaning a partial build can fail if the output directory for libbpf wasn't created: $ make -C tools/bpf/bpftool O=/tmp/bpf clean /bin/sh: line 0: cd: /tmp/bpf/libbpf/: No such file or directory tools/scripts/Makefile.include:17: *** output directory "/tmp/bpf/libbpf/" does not exist. Stop. make: *** [Makefile:36: /tmp/bpf/libbpf/libbpf.a-clean] Error 2 As a result make never gets around to clearing the leftover objects. Add the libbpf output directory as clean dependency to ensure clean always succeeds (similarly to the "descend" macro). The directory is later removed by the clean recipe. Signed-off-by: Jean-Philippe Brucker <jean-philippe@linaro.org>
The bpftool build first creates an intermediate binary, executed on the host, to generate skeletons required by the final build. When cross-building bpftool for an architecture different from the host, the intermediate binary should be built using the host compiler (gcc) and the final bpftool using the cross compiler (e.g. aarch64-linux-gnu-gcc). Generate the intermediate objects into the bootstrap/ directory using the host toolchain. Signed-off-by: Jean-Philippe Brucker <jean-philippe@linaro.org>
Makefile.include defines variables such as OUTPUT and CC for out-of-tree build and cross-build. Include it into the runqslower Makefile and use its $(QUIET*) helpers. Signed-off-by: Jean-Philippe Brucker <jean-philippe@linaro.org>
Enable out-of-tree build for runqslower. Only set OUTPUT=.output if it wasn't already set by the user. Signed-off-by: Jean-Philippe Brucker <jean-philippe@linaro.org>
When cross building runqslower for an other architecture, the intermediate bpftool used to generate a skeleton must be built using the host toolchain. Pass HOSTCC and HOSTLD, defined in Makefile.include, to the bpftool Makefile. Signed-off-by: Jean-Philippe Brucker <jean-philippe@linaro.org>
Commit ba2fd56 ("tools/bpftool: Support passing BPFTOOL_VERSION to make") changed BPFTOOL_VERSION to a recursively expanded variable, forcing it to be recomputed on every expansion of CFLAGS and dramatically slowing down the bpftool build. Restore BPFTOOL_VERSION as a simply expanded variable, guarded by an ifeq().
