The change that you applied to your lttng-ust <a href="http://configure.ac" target="_blank">configure.ac</a> should look<br>
like this:<br>
<br>
diff --git a/<a href="http://configure.ac" target="_blank">configure.ac</a> b/<a href="http://configure.ac" target="_blank">configure.ac</a><br>

Make sure after making this change that you run the autoreconf command<br>
like this:<br>
<br>
autoreconf -i -v<br>
<br>
And then rerun ./configure with your platform specific flags.<br>
The configure test should now pass without problem :).<br>
<br>
Thanks,<br>
