Code Coverage.   
I am doing a code coverage activity using gcov and lcov. In Linux we are able to generate the .bb and .bbg files during 
the cross compilation of the source file for a QNX specific (QNX 6.3.2) shle processor. The .da file was created 
successfully once we execute the executable”. But lcov command is not working. Its showing the error “ERROR: cannot 
read .gcno file. During compilation only .bb and .bbg files are getting created;no .gcno files are created. 

How I can use this .bb and .bbg files with lcov to generate the .info file. It will be great if you can help me ... 
Thanks, 
Avinash

Re: Code Coverage.   
Hi Avinash,

What kind of project are you working on? Is it a QNX C/C++ Project or a standard C/C++ Project?

I was able to use the code coverage tool in QNX IDE for a QNX C/C++ project. But I did not use lcov, instead I used the 
code-coverage perspective of QNX IDE to view my code coverage results.

The *.bb and *.bbg files are produced during compilation (as you say) but I dont think these are used to view code 
coverage information.

Regards
Sunil

RE: Code Coverage.   
Hi Sunil,

We are working on a QNX C Project.
I was not using the QNX IDE for codecoverage, I was using the QNX
utilities - gcov and lcov for code coverage.The *.bb and *. bbg files
are created at the time of compilation. *.da files generated in the
target are copied to our QNX workspace. This *.da file is  used to
create codecoverage files.
 I feel IDE will be more user friendly. I have used the IDE onle for CPU
Analysis. It will be interesting if I can use it for code coverage also.
Can you pls let me know how to use the code-coverage perspective of QNX
IDE to view my code coverage results.

Thanks,
Avinash Narayanan

RE: Code Coverage.   
Hi, Avinash,

You can use the IDE Code Coverage tool to create and view your program
coverage data. The IDE users' guide has one section for Code Coverage.
You can view it here:

http://www.qnx.com/developers/docs/6.4.1/ide_en/user_guide/coverage.html

In the mean time you can run the IDE Code Coverage example program to be
familiar with the tool.

HTH,
Andy

Re: RE: Code Coverage.   
Avinash,

I was going to post the same link that Andy has mentioned. It has a very detailed explanation on how to enable code 
coverage for QNX projects and how to retrieve the code coverage info using the Code Coverage Perspective.

However, I had some problems while trying to retrieve the code coverage data from the target when working on a Standard 
Make project.
