When i run the code coverage to output in html, I get the error message:
CalledProcessError: Command 'lcov -r mycoverage.2.temp "/../generated/*" -o mycoverage.2' returned non-zero exit status 255
The gcov -v gives:
gcov (GCC) 3.4.2
I tried to find what exit status 255 means, but with no luck.
Any expert please who might be able to help?

I've executed sudo xcode-select -s /Applications/Xcode.app/Contents/Developer But still wrong
Running through the setup example from gcovr here: https://gcovr.com/en/stable/guide.html#getting-started I can build the file and am seeing the following output from running gcovr -r .:
% gcovr -r .

If I run gcov example.cpp directly I can see that the generated .gcov data is correct:
% gcov example.cpp
File 'example.cpp'
Lines executed:87.50% of 8
Creating 'example.cpp.gcov'
I am unsure where the disconnect between this gcov output and the gcovr interpretation of it is.
I have tried downgrading to an older gcovr version, running the command on other projects, and switching python versions, but have not seen any different behavior.
My gcov and gcc are from the Xcode command line tools. gcovr was pip installed (within pyenv with python 3.8.5)
Edit: adding verbose output:

In xcode it is a good idea to generate documentation during build your library.. I am using headerdoc2HTML command .. to make it run with build phase I've added it to build phase script (shell script) like this:
headerdoc2html -o "outputPath" "myHeader.h"
But it always gives me an error:
Command /bin/sh emitted errors but did not return a nonzero exit code to indicate failure
Even the documentation is generated but it gives me an error .. if I remove this command every thing goes fine!
I checked with -d parameter I did not get where is the error
Any help with that? is there a way to check if the command did not return 0 then don't show error (ignore all warnings and errors)?
EDIT:
I just made sure that the command is ok and no problem with it by doing this check:
if headerdoc2html -q -j -o "outputPath" "myHeader.h"
then
echo "Documents generated successfully!"
fi
While the problem is from the command it self and don't effect the over all build phase so it is good idea to not show the warnings and errors from headerdoc2html command.
The easiest way to do that is to hide any emitted errors from it like by redirect errors to null like this:
headerdoc2html -o "outputPath" "myHeader.h" >/dev/null 2>/dev/null
For the codesign command, where can I see what the numbered error code meanings? I'm exit status 1 and exit status 74. I'm curious on what these mean.
After upgrading to Xcode 4.3.2. I'm getting a metric ton of build errors.
A whole line of them are error code 255
gcc-4.2: error trying to exec '/usr/bin/arm-apple-darwin11-gcc-4.2.1': execvp: No such file or directory
Command /usr/bin/gcc-4.2 failed with exit code 255
I noticed that there is no /usr/bin/arm-apple-darwin11-gcc-4.2.1 file on my machine. Could this be the source of the problem?
What's the output of this command?
$ printenv | grep "CC="
It might be honoring your C Compiler (CC) selection. I was getting similar errors (through cocoapods) and doing an
$ export CC=
fixed it for me.
