This is just ctest's way of helping you get rid of your warnings. All warnings should be treated as errors... (Just joking, please don't flame... :-)<br><br><br>git blame shows that line as having been last modified in 2004. Specifically:<br>
<br>git blame -- Source/CTest/cmCTestBuildHandler.cxx<br><br> 8a2bedda (Ken Martin 2004-09-07 10:37:39 -0400 47) "([^ :]+):([0-9]+): ([^ \\t])",<br><br>Regardless of the reason or justification, it's been that way for nearly 7 years. I would venture a guess to say that some old compiler from the 7-years-ago era had error output that matched such lines.<br>
<br>Better to "too aggressively" identify errors than to miss some.<br><br>You could use a custom error exception regex to avoid reporting these warning lines as errors if you can't simply eliminate the warnings.<br>
<br>I'd rather not remove it as a built-in error regex unless the vast majority of people listening in here speak up in opposition... Keeping it the same means no change in behavior. Removing it means NOT matching some lines as errors that are presently matched as errors -- bad news if it really is an error line for somebody's build...<br>

Hello,<div><br></div><div>JC and I discovered some weird behavior in CTest where some warnings were being reported as errors in Build.xml. After some digging I found that the output was matching one of the cmCTestErrorMatches, specifically "([^ :]+):([0-9]+): ([^ \\t])".</div>
