[lttng-dev] lttng view => [error] at line 1269: token "(": syntax error, unexpected LPAREN, expecting SEMICOLON or COMMA

[John Smith]

Philippe,

On "3.19.0-30-generic #34~14.04.1-Ubuntu", apt-get won't install anything
else, is LTTng 2.6 (or 2.7) user space backward compatible with kernel 3.19?
I remember a while back trying to build the 2.7 kernel LTTng modules and
got build errors, required additional packages versions that were not
available for 3.19 and upgrading to a newer kernel is problematic,

thanks, John
