DETAILS

27       To obtain coverage of XS files they must first be compiled with the
28       appropriate options.  In a standard Makefile environment, such as that
29       created by ExtUtils::MakeMaker, this can be accomplished with the
30       command:
31
32        HARNESS_PERL_SWITCHES=-MDevel::Cover make test \
33          CCFLAGS=-O0\ -fprofile-arcs\ -ftest-coverage \
34          OTHERLDFLAGS=-fprofile-arcs\ -ftest-coverage
35
36       If you have already built your object files it may be necessary to run
37       make clean first, or to find some other way to ensure that they get
38       rebuilt with the options gcov requires.
39
40       Now the code coverage data has been collected "gcov" needs to be run:
41
42        gcov Mylib.xs
43
44       This will create one or more gcov files on which you can run
45       "gcov2perl":
46
47        gcov2perl Mylib.xs.gcov
48
49       Finally, "cover" should be run as usual with any options required:
50
51        cover
52
53       If you are running everything with standard options, you can do all
54       this with one command:
55
56        cover -test
57

EXIT STATUS

59       The following exit values are returned:
60
61        0   All files converted successfully
62        >0  An error occurred.
