Using gcov

Hi,

I am using gcov to get code coverage for my program written in C++, I am able to do it without any problem when i don't have a directory structure, for my program I am a directory structure as below

Code:

./src/ -- containing all my source files

./obj/ -- containing all my object files

./header/ -- containing all my header files

../../lib/  -- containing a static library, which will be used by 
                my program 

there is a makefile in the current directory which creates my executable

Quote:

do i need to compile the static library also with the options of gcov i.e. -fprofile-arcs -ftest-coverage, because it is the library that i need to check for coverage.

Kindly help on how use gcov in this situation.

NAME

       gcov2perl - convert gcov files to Devel::Cover databases

VERSION

       version 1.03

SYNOPSIS

	gcov2perl -h -i -v -db database gcov_files

DESCRIPTION

       Convert gcov files to Devel::Cover databases.

OPTIONS

       The following command line options are supported:

	-db database	- specify the database to use

	-h -help	- show help
	-i -info	- show documentation
	-v -version	- show version

DETAILS

       To obtain coverage of XS files they must first be compiled with the appropriate options.  In a standard Makefile environment, such as that
       created by ExtUtils::MakeMaker, this can be accomplished with the command:

	HARNESS_PERL_SWITCHES=-MDevel::Cover make test 
	  CCFLAGS=-O0 -fprofile-arcs -ftest-coverage 
	  OTHERLDFLAGS=-fprofile-arcs -ftest-coverage

       If you have already built your object files it may be necessary to run make clean first, or to find some other way to ensure that they get
       rebuilt with the options gcov requires.

       Now the code coverage data has been collected "gcov" needs to be run:

	gcov Mylib.xs

       This will create one or more gcov files on which you can run "gcov2perl":

	gcov2perl Mylib.xs.gcov

       Finally, "cover" should be run as usual with any options required:

	cover

       If you are running everything with standard options, you can do all this with one command:

	cover -test

EXIT STATUS

       The following exit values are returned:

	0   All files converted successfully
	>0  An error occurred.
