[kush930]

Hi all.

I cloned successfully from link: https://github.com/linux-test-project/lcov.git

I want to build on x86 machine, I followed all required steps.

Looks like your system is missing at least one perl module. README has some suggestions for how to install them.

I am not getting exact idea to resolve this issue, whatever previous package related issue, I was getting those are resolved.

Which platform and version? Which compiler and version? Which perl version? Which lcov version?

The easiest way to debug is likely to be:

$ cd ..../tests/lcov/extract
$ ./extract.sh -v  # run test with verbose printing

And see what command failed and what it was trying to do

Hi henry2cox and all,

As per your suggestion, I executed command and got one issue, can you suggest me where i am doing wrong.

Not sure why you are running as root. That seems...unwise.

The tool is looking for a file whose name is 'a-extract.gcno' (to match the file 'a-extract.gcda' which it found in your run directory. It was unable to find that file. You might want to run find . -name '*.gc*' from your run directory, to see where things are and whether your compiler generated the compile-time data file or not.

Note that when I run this test, the basename of the .o and the gcno/gcda is 'extract' (extract.o, extract.gcno, extract.gcda). From the data you provide: I cannot see where your apparent 'a-' prefix came from.

Should you want to debug issues with this tool - or any other tool - by yourself: consider that the test is mimicking your flow - in this case, compile/run tests/generate coverage. Think about what each step is trying to do. Check that each step did what it was supposed to do (e.g., by running it separately in your shell). If it didn't do what was expected - or you are unsure what it was supposed to do: look at error messages, read man pages, do some internet searches - and then ask for help when you really are stuck.

Hi henry2cox,

It was giving permission denied error, so I was running as root. Thanks for your suggestion, I will work on this.

I'm attempting to clean up the issue list. There have been no updates in a while - so I guess that the issue is resolved or you no longer care about it. If it is resolved: then it would be good to update this issue so that anyone else who hits a similar issue can benefit.

I will go ahead and close this issue in a couple of days - unless there is something that still needs to be done here.

[henry2cox]

Closing this issue now. If there is still a problem, please feel free to reopen this issue or file a new one. Please describe the problem in detail and provide a testcase which illustrates the issue, if possible.
