<br>
On Mac two OMPT tests (see below) fail because the linking option "--no-as-needed” is not recognized (using LLVM/Clang 6.0.1)<br>
Does anyone know a workaround for this?<br>
<br>
Failing Tests (2):<br>
libomp :: ompt/loadtool/tool_available/tool_available.c<br>
libomp :: ompt/loadtool/tool_not_available/tool_not_available.c<br>
<br>
Thanks.<br>
