Perf build in Ubuntu 18.10 fails
I upgraded my Ubuntu installation to 18.10. The kernel I am using is "4.18.0-13-lowlatency".
I have installed perf using linux-tools-common package. Perf works but I can't use the python/perl scripting abilities.
Python scripting not supported. Install libpython and rebuild perf to enable it.
For example:
# apt-get install python-dev (ubuntu)
# yum install python-devel (Fedora)
etc.
I followed the steps here, cloned the corresponding release of Ubuntu-Cosmic. But when I try to build perf, I get following error:
util/parse-events.c: In function ‘parse_events__scanner’:
util/parse-events.c:1795:8: error: implicit declaration of function ‘parse_events_lex_init_extra’; did you mean ‘parse_events_set_extra’? [-Werror=implicit-function-declaration]
ret = parse_events_lex_init_extra(start_token, &scanner);
^~~~~~~~~~~~~~~~~~~~~~~~~~~
parse_events_set_extra
util/parse-events.c:1795:8: error: nested extern declaration of ‘parse_events_lex_init_extra’ [-Werror=nested-externs]
Any hints on how to solve this problem?
