[LTP] not able to generate HTML output

[LTP] not able to generate HTML output

[Pramendra Singh]

[-- Attachment #1.1: Type: text/plain, Size: 1617 bytes --]

Hi everyone,

Good afternoon!

I am new to LTP and using it to test my code for PPC architecture.
I have patched my kernel with GCOV and it seems working fine. But
I  am not able to get the HTML of code coverage/

I am cross compiling the kernel on my server for PPC and putting the image
to my PPC target board. After test I am able to get .gcda file for my .c file
and I take it back to my server where my kernel  source is there.

I use ppc_85xx-gcov for generating coverage and after that I use
"geninfo "  utiliy available in lcov-1.8 but I get error "not able to open
Basic block .bb files."

Problem is that in my source code there is no .bb files but .gcno files are there
and I think that is because my gcc compiler version is  3.4.1 but "geninfo" binary
is compiled with some low version gcc.

So please let me know where to get source code for geninfo and genhtml so
That I can compile them for  PPC architecture with my gcc version.

Or let me know if I am doing anything wrong is code coverage process.

Thanks in advance!

Thanks and Regards

Hi Pramendra,
Can you let us know on which kernel/distro you are trying to take coverage ?

Thanks
Rishikesh

I am cc'ing peter, as he will definitely help you with this information now.

Re: [LTP] not able to generate HTML output

[Peter Oberparleiter]

If you're cross-compiling your kernel and want to run lcov on the build 
machine, you need to specify the full path to the cross-compiler gcov 
tool, otherwise lcov will attempt to use the gcov tool of the locally 
installed gcc package.

Example:

   lcov -c -d /path/to/files --gcov-tool /path/to/ppc_85xx-gcov -o x.info

Also note that lcov can do the copying of .gcda files for you if a perl 
interpreter and the lcov file is available. On the test machine, run:

   lcov -c --to-package package

Copy the package file to the build machine. On the build machine, run:

   lcov -c --from-package package --gcov-tool ...


Regards,
   Peter Oberparleiter
