Summary0013657: Fix for bug /Bug/view.php?id=13121 not working
DescriptionAfter running into the issue reported in bug 0013121, I grabbed the 2.8.10 source and built it. The problem is still there for me (see sample output below).

I compiled cmake with gcc 4.7.2 (the default for Ubuntu 12.10). gcov is also at version 4.7.2.

Here are the first few lines of the output I get (there are tons more like this):

$ make coverage

Sorry, clarification: the issue in bug 0013121 is indeed fixed, but there is all this noise about unrecognized output from gcov. In addition, CTest terminates and does not run other post-processing commands that I have in my custom target (see below). It would be great to not get the noise and zero exit status.

Unknown gcov output line: [Removing 'ResourcePtr_test.cpp.gcda##streambuf.gcov']
Unknown gcov output line: [No executable lines]
Unknown gcov output line: [Removing 'ResourcePtr_test.cpp.gcda##istream.gcov']

Is your project publicly available? Or does it possibly demonstrate the same symptoms when building the https://github.com/dlrdave/SmallAndFast [^] project? Or can you modify that project minimally such that it does demonstrate the same symptoms?

Thanks.

I'm afraid the project isn't publicly available right now. I'll try and see whether I can come up with a stand-alone test case, or try with the SmallAndFast project and see what I get there.

Thanks,

Michi.

I can reproduce this with a trivial file added to the SmallAndFast project (attached).

To reproduce:

$ cmake .
$ make
$ make test
$ make NightlyCoverage

This produces:

$ make NightlyCoverage

Thanks for the steps to reproduce. I'll take a look at this one when I get a chance.

This should fix it (in CMake 'next' now):
