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 \
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:
This will create one or more gcov files on which you can run
Finally, "cover" should be run as usual with any options required:
If you are running everything with standard options, you can do all this with
The following exit values are returned:
0 All files converted successfully
