| # SYNOPSIS |
| # |
| # AX_CODE_COVERAGE() |
| # |
| # DESCRIPTION |
| # |
| # Defines CODE_COVERAGE_CPPFLAGS, CODE_COVERAGE_CFLAGS, |
| # CODE_COVERAGE_CXXFLAGS and CODE_COVERAGE_LIBS which should be included |
| # in the CPPFLAGS, CFLAGS CXXFLAGS and LIBS/LIBADD variables of every |
| # build target (program or library) which should be built with code |
| # coverage support. Also add rules using AX_ADD_AM_MACRO_STATIC; and |
| # $enable_code_coverage which can be used in subsequent configure output. |
| # CODE_COVERAGE_ENABLED is defined and substituted, and corresponds to the |
| # value of the --enable-code-coverage option, which defaults to being |
| # disabled. |
| # |
| # Test also for gcov program and create GCOV variable that could be |
| # substituted. |
| # |
| # Note that all optimization flags in CFLAGS must be disabled when code |
| # coverage is enabled. |
| # |
| # Usage example: |
| # |
| # configure.ac: |
| # |
| # AX_CODE_COVERAGE |
| # |
| # Makefile.am: |
| # |
| # include $(top_srcdir)/aminclude_static.am |
| # |
| # my_program_LIBS = ... $(CODE_COVERAGE_LIBS) ... |
| # my_program_CPPFLAGS = ... $(CODE_COVERAGE_CPPFLAGS) ... |
| # my_program_CFLAGS = ... $(CODE_COVERAGE_CFLAGS) ... |
| # my_program_CXXFLAGS = ... $(CODE_COVERAGE_CXXFLAGS) ... |
| # |
| # clean-local: code-coverage-clean |
| # distclean-local: code-coverage-dist-clean |
| # |
| # This results in a "check-code-coverage" rule being added to any |
| # Makefile.am which do "include $(top_srcdir)/aminclude_static.am" |
| # (assuming the module has been configured with --enable-code-coverage). |
| # Running `make check-code-coverage` in that directory will run the |
| # module's test suite (`make check`) and build a code coverage report |
| # detailing the code which was touched, then print the URI for the report. |
| # |
| # This code was derived from Makefile.decl in GLib, originally licensed |
| # under LGPLv2.1+. |
