I am trying to get code coverage on my CMake based project (which consists of several targets).
First I generate gcno files with:
lcov -b . -d . -o coverage.output --capture --initial
The *.gcno are generated in
build_dir/[target_dir]/CMakeFiles/[target_dir].dir
Then I run my tests which generate *.gcna files in
build_dir/tests/CMakeFiles/[target_dir].dir
When I now run lcov again:
lcov -b . -d . -o coverage.output --capture
I get the following error:
Scanning . for .gcda files ...
Found 23 data files in .
Processing Base.dir/DateTools.cpp.gcda
geninfo: ERROR: build_gcov/tests/CMakeFiles/Base.dir/DateTools.cpp.gcno: could not open file
When I manually move the *.gcno file to the directory where the *.gcda is generated it seems to work.
Thanks for your help!!!
我已经弄明白了如何将lcov与CMake一起使用并将所有内容捆绑在一个cmake模块中 。
