gcov

I am recently using gcov to collect the code coverage info. gcov plays well with executable application :) , but when I try to load a .so file, I got this error: unknown symbol __gcov_merge_add. Then I search on Google and someone said adding -lgcov to the link flag(LDFLAGS), I did add this option and it didn't work. I also try on --coverage option in link flag, cannot get rid of this error. Can someone help on this issue? Thank you. deuberger I ran into that problem too, but have since solved it. I just use the --coverage option in both CPPFLAGS and LDFLAGS. I think that should take care of

I'm using a test-generating tool called KLEE, that creates lots of tests for my C99-Code. Afterwards I run the tests and check line coverage with gcov. Gcov seems to update coverage data at the end of the run upon successful completion. However, some tests fail (assert statements that are not true), which leads to aborting the program and gcov not counting the lines covered in this run. Is there any way that gcov flushes information on any exit (not only on successful)? Call void __gcov_flush(void) (from libgcov.a which is linked in by -fprofile-arcs option of compiler) in your assert code,

I'm on a linux machine, trying to build a project using cmake that does out of source builds. For code coverage, I looked into gcov and followed a simple tutorial that generate appropriate files for a sample helloWorld.cpp program. The only requirement were to compile with -fprofile-arcs -ftest-coverage flags & link with -lgcov flag, which can be done altogether with -coverage flag. Now here comes the tricky part. I have a CMakeLists.txt wit contents as shown below: cmake_minimum_required (VERSION 2.8) project (SomeName) SET(GCC_COVERAGE_COMPILE_FLAGS "-g -O0 -coverage -fprofile-arcs -ftest

I measure coverage for my code using gcov library and I would like to generate coverage report in user-friendly format. I've found lcov utility for that, but it's not compatibile with Windows environment (mainly because of the way the paths are parsed). Does anyone know about actively supported lcov port for Windows? It seems that making it work on Windows would be quite easy (it think it might even be solved by few creative batch/perl scripts that mimic the behavior of unix shell commands), and the tool is quite useful, so I suppose someone might have already done it.

On one project, I'm running the test cases on three different executables, compiled with different options. Depending on the options, some code paths are taken or not. Right now, I'm only using the coverage data from one executable. I'm using gcovr to generate a XML that is then parsed by Sonar: gcovr -x -b -r . --object-directory=debug/test > coverage_report.xml I have three sets of gcda and gcno files, but I don't know how to generate a global report of them. Is there any way to do that ? Assuming that by "compiled with different options" you mean that you compile such that you obtain

For my header-only C++ library (lots of templates etc) I use GCov to check test coverage. However, it reports 100% coverage for all headers because the unused functions aren't generated by the compiler in the first place. Manually spotting uncovered functions is easy but defeats the purpose of continuous integration… How does one solve this automatically? Should I just use "lines hit / LOC" as my coverage metric and just never reach 100% again? Apart from the usual flags to GCC controlling inlining; --coverage -fno-inline -fno-inline-small-functions -fno-default-inline You can instantiate your
