Subject: [PATCH 03/15] perf evsel: Remove symbol_conf usage
Date: Fri, 15 Apr 2016 18:50:49 -0300 [thread overview]
Message-ID: <1460757061-3283-4-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1460757061-3283-1-git-send-email-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
# perf test -v python
16: Try 'import perf' in python, checking link problems :
--- start ---
test child forked, pid 672
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: /tmp/build/perf/python/perf.so: undefined symbol:
symbol_conf
test child finished with -1
---- end ----
Try 'import perf' in python, checking link problems: FAILED!
#
To fix it just pass a parameter to perf_evsel__fprintf_sym telling if
callchains should be printed.
