The following issue has been SUBMITTED. ====================================================================== http://www.cmake.org/Bug/view.php?id=11717 ====================================================================== Reported By: Marco Craveiro Assigned To: ====================================================================== Project: CMake Issue ID: 11717 Category: CTest Reproducibility: always Severity: minor Priority: normal Status: new ====================================================================== Date Submitted: 2011-01-17 17:21 EST Last Modified: 2011-01-17 17:21 EST ====================================================================== Summary: gcov: handling the same file name in different directories Description: i've been trying to use ctest's coverage support on a project that uses the same file name in different directories, e.g.:
serialisation/some_class_name.hpp streaming/some_class_name.hpp ... due to the parameters passed in to gcov by ctest, this results in naming clashes when generating the *.gcov files from the different *.gcda input files. symptoms of this problem: ------------------------- 1. errors such as: Error(s) while accumulating results: Problem reading source file: some_file_name line:45 out total: 49 Looks like there are more lines in the file: }; Looks like there are more lines in the file: Looks like there are more lines in the file: <snip> debugging ctest revealed that each of these is actually an error in a different file, all of which suffering from the name clashing. 2. an error at the end of ctest even though the submission is successful: <snip> Submission successful Error in read script: some_ctest_script.cmake Steps to Reproduce: the following steps assume a linux environment with all development tools installed (gcov, gcc, cmake, tar, etc). 1. download the attachment cmake_gcov_bug.tgz. it contains the smallest amount of code i could come up with that illustrates the problem. 2. unpack it by running: $ tar -zxf cmake_gcov_bug.tgz 3. run ctest: $ cd cmake_gcov_bug $ ctest -S CTest.cmake -VV 4. An error will occur: <snip> Error(s) while accumulating results: Looks like there are more lines in the file: class some_class_a <snip> Error in read script: /home/marco/code/cmake_gcov_bug/CTest.cmake Additional Information: - the errors occur due to the gcov parameters passed in, which result in using "short" filenames. - the problem should be fixed by adding the flag -p (--preserve-paths) to the gcov invocation in cmCTestCoverageHandler::HandleGCovCoverage (Source/CTest/cmCTestCoverageHandler.cxx). this code uses the gcov generated filename to process the file and works correctly with a longer filename. - once processed into a SingleFileCoverageVector, it appears nothing else relies on the original gcov file name. - patch will be attached subsequently as only one file can be uploaded from submission form. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2011-01-17 17:21 Marco Craveiro New Issue 2011-01-17 17:21 Marco Craveiro File Added: cmake_gcov_bug.tgz ====================================================================== _______________________________________________ cmake-developers mailing list [email protected] http://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
