Windows 11 GCOV v6.0 Python 3.11.3 gcc.exe (Rev2, Built by MSYS2 project) 12.1.0 gcov (Rev2, Built by MSYS2 project) 12.1.0

I compile my project, run the executable and get a full set of .gcda and .gcno files as expected, however when I run:

gcovr -r . within the folder with all of the .gcda and .gcno files I get:

PS C:\emwi_testframework\Application\Project\GCC\obj> gcovr -r . (ERROR) Trouble processing 'C:/emwi_testframework/Application/Project/GCC/obj/ewheap.gcda' with working directory 'C:\emwi_testframework\Application\Project\GCC\obj'.

I would appreciate any suggestions as I am new to gcov.

  • How do you invoke GCC? Is it in your PATH? What happens when you run `gcov --help`? Gcovr needs gcov from the GCC project, which should have been compiled alongside the compiler. If gcov is somewhere else, you can tell gcovr about this with `gcovr --gcov-executable C:/path/to/gcov`.
