Subject: Stop build if CONFIG_TRACEPOINTS is not set
X-Git-Tag: v2.2.0-rc2~5
X-Git-Url: http://git.lttng.org/?p=lttng-modules.git;a=commitdiff_plain;h=699f9673466e1a6537ad23cc697b79660639f260

Stop build if CONFIG_TRACEPOINTS is not set

Previously it just tries to compile with zero modules, which is
confusing if you thought you had configured everything correctly. Now it
throws an error which tells which went wrong.

Fixes #506
