So, just with your patch:
[acme@five perf]$ rm -rf /tmp/build/perf ; mkdir -p /tmp/build/perf [acme@five perf]$ make PYTHON=python3 -C tools/perf O=/tmp/build/perf install-bin |& grep python ... libpython: [ OFF ] Makefile.config:750: No 'Python.h' (for Python 2.x support) was found: disables Python support - please install python-devel/python-dev CC /tmp/build/perf/tests/python-use.o [acme@five perf]$
[acme@five perf]$ rpm -q python2-devel python3-devel python-devel package python2-devel is not installed python3-devel-3.7.6-2.fc31.x86_64 package python-devel is not installed [acme@five perf]$
[acme@five perf]$ cat /tmp/build/perf/feature/test-libpython.make.output /bin/sh: --configdir: command not found [acme@five perf]$ cat /tmp/build/perf/feature/test-libpython test-libpython.make.output test-libpython-version.make.output [acme@five perf]$ cat /tmp/build/perf/feature/test-libpython-version.make.output /bin/sh: --configdir: command not found [acme@five perf]$
Without your patch:
[acme@five perf]$ rm -rf /tmp/build/perf ; mkdir -p /tmp/build/perf [acme@five perf]$ make PYTHON=python3 -C tools/perf O=/tmp/build/perf install-bin |& grep python ... libpython: [ on ] GEN /tmp/build/perf/python/perf.so MKDIR /tmp/build/perf/scripts/python/Perf-Trace-Util/ CC /tmp/build/perf/scripts/python/Perf-Trace-Util/Context.o LD /tmp/build/perf/scripts/python/Perf-Trace-Util/perf-in.o CC /tmp/build/perf/tests/python-use.o CC /tmp/build/perf/util/scripting-engines/trace-event-python.o INSTALL python-scripts [acme@five perf]$
[acme@five perf]$ ldd /tmp/build/perf/perf |& grep python libpython3.7m.so.1.0 => /lib64/libpython3.7m.so.1.0 (0x00007f11dd1ee000) [acme@five perf]$ perf -vv |& grep -i python libpython: [ on ] # HAVE_LIBPYTHON_SUPPORT [acme@five perf]$
What am I missing?
[acme@five perf]$ cat /etc/redhat-release Fedora release 31 (Thirty One) [acme@five perf]$
