Hi, We're ramping up our testing using CDash, CTest, and CMake. I started a coverage build but get no coverage information. I'm not sure how to debug ctest as it doesn't produce coverage information properly. Long post, sorry.
Environment: $ ctest -version ctest version 2.7-20080417 $ cmake -version cmake version 2.7-20080417 $ gcc -v Using built-in specs.

However, ctest does not produce any coverage information at all, though the file (./Testing/CoverageInfo/NoOp.cxx.gcda##NoOp.cxx.gcov) has the correct coverage information in it. $grep NoOp Testing/20081222-1437/* Testing/20081222-1437/CoverageLog-2.xml: <File Name="NoOp.cxx" FullPath="./Testing/Source/NoOp.cxx"> So it would appear that ctest is not properly generating coverage information. Any help, thoughts or suggestions?
