6 gcov2perl - convert gcov files to Devel::Cover databases
7
9 gcov2perl -h -i -v -db database gcov_files
10
12 Convert gcov files to Devel::Cover databases.
13
15 The following command line options are supported:
16
17 -db database - specify the database to use
18
19 -h -help - show help
20 -i -info - show documentation
21 -v -version - show version
22
24 To obtain coverage of XS files they must first be compiled with the
25 appropriate options. In a standard Makefile environment, such as that
26 created by ExtUtils::MakeMaker, this can be accomplished with the
27 command:
28
29 HARNESS_PERL_SWITCHES=-MDevel::Cover make test \
30 CCFLAGS=-O0\ -fprofile-arcs\ -ftest-coverage \
31 OTHERLDFLAGS=-fprofile-arcs\ -ftest-coverage
32
33 If you have already built your object files it may be necessary to run
34 make clean first, or to find some other way to ensure that they get
35 rebuilt with the options gcov requires.
36
37 Now the code coverage data has been collected "gcov" needs to be run:
38
39 gcov Mylib.xs
40
41 This will create one or more gcov files on which you can run
42 "gcov2perl":
43
44 gcov2perl Mylib.xs.gcov
45
46 Finally, "cover" should be run as usual with any options required:
47
48 cover
49
50 If you are running everything with standard options, you can do all
51 this with one command:
52
53 cover -test
54
56 The following exit values are returned:
57
58 0 All files converted successfully
59 >0 An error occurred.
