Subject: TRACELOG_LOGLEVEL not observed when using g++
Date: Tue, 11 Oct 2016 11:24:11 -0500	[thread overview]
Message-ID: <7afb6e0b2c85d1526ff6d162aba856e1.squirrel__37896.8001147316$1476203122$gmane$org@email.powweb.com> (raw)

The TRACELOG_LOGLEVEL doesn't work when compiling for C++ using the
gcc toolchain. The events all end up as TRACE_DEBUG_LINE.

For instance, using the easy-ust example from lttng-ust to demonstrate.

The initial run is built as shipped, the second run is built on g++
(using the AM_CC override in the make file).

This initial report is done using
