<br>
If I were you, I would:<br>
<br>
(1) use gcov on a Linux build of your software for coverage measurement, using the "Unix Makefiles" generator and the right gcov flags<br>
or<br>
(2) buy Bullseye for the Mac, as NoRulez suggested his company did because they couldn't get a reliable coverage build using gcov on the Mac<br>
<br>
This is not a ctest problem. This is a "gcov doesn't work right on the Mac" problem.<br>
<br>
If somebody would like to claim gcov does work right on the Mac, I would love to see the proof. If anybody is doing it successfully, please do share your scripts and a link to the dashboard results you get using it. (And any hints we might need to replicate it ourselves...)<br>
