Subject: [PATCH v2 2/4] perf test: Skip the python binding builtin test case with NO_LIBPYTHON=1
From: Arnaldo Carvalho de Melo <acme@...hat.com>
The python_use test suite was being built and tested even when the
python binding that it is designed to test is not being built, fix it by
making it skip the test with an informative message.
Testing this patch:
When building with NO_LIBPYTHON=1, i.e. explicitely disabling linking
against libpython and thus not building the python binding:
$ perf test 17
17: 'import perf' in python : Skip (No python binding, enable by not using NO_LIBPYTHON=1.)
$
Not disabling linking with libpython, the default, that results in the
python binding being built:
$ perf test 17
17: 'import perf' in python : Ok
