Subject: [PATCH AUTOSEL 4.18 06/27] perf python: Use -Wno-redundant-decls to build with PYTHON=python3
Date: Mon, 22 Oct 2018 06:19:03 -0400 [thread overview]
Message-ID: <20181022101924.40531-6-sashal@kernel.org> (raw)
In-Reply-To: <20181022101924.40531-1-sashal@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
[ Upstream commit 05a2f54679861deb188750ba2a70187000b2c71f ]
When building in ClearLinux using 'make PYTHON=python3' with gcc 8.2.1
it fails with:
GEN /tmp/build/perf/python/perf.so
In file included from /usr/include/python3.7m/Python.h:126,
from /git/linux/tools/perf/util/python.c:2:
/usr/include/python3.7m/import.h:58:24: error: redundant redeclaration of ‘_PyImport_AddModuleObject’ [-Werror=redundant-decls]
PyAPI_FUNC(PyObject *) _PyImport_AddModuleObject(PyObject *, PyObject *);
^~~~~~~~~~~~~~~~~~~~~~~~~
/usr/include/python3.7m/import.h:47:24: note: previous declaration of ‘_PyImport_AddModuleObject’ was here
PyAPI_FUNC(PyObject *) _PyImport_AddModuleObject(PyObject *name,
^~~~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
error: command 'gcc' failed with exit status 1
And indeed there is a redundant declaration in that Python.h file, one
with parameter names and the other without, so just add
-Wno-error=redundant-decls to the python setup instructions.
Now perf builds with gcc in ClearLinux with the following Dockerfile:
# docker.io/acmel/linux-perf-tools-build-clearlinux:latest
FROM docker.io/clearlinux:latest

RUN swupd update && \
swupd bundle-add sysadmin-basic-dev
RUN mkdir -m 777 -p /git /tmp/build/perf /tmp/build/objtool /tmp/build/linux && \

USER perfbuilder
COPY rx_and_build.sh /
ENV EXTRA_MAKE_ARGS=PYTHON=python3
ENTRYPOINT ["/rx_and_build.sh"]
Now to figure out why the build fails with clang, that is present in the
above container as detected by the rx_and_build.sh script:
clang version 6.0.1 (tags/RELEASE_601/final)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: /usr/sbin
make: Entering directory '/git/linux/tools/perf'
