# =========================================================================== # https://www.gnu.org/software/autoconf-archive/ax_code_coverage.html # =========================================================================== # # 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+. # # LICENSE # # Copyright (c) 2012, 2016 Philip Withnall # Copyright (c) 2012 Xan Lopez # Copyright (c) 2012 Christian Persch # Copyright (c) 2012 Paolo Borelli # Copyright (c) 2012 Dan Winship # Copyright (c) 2015,2018 Bastien ROUCARIES # # This library is free software; you can redistribute it and/or modify it # under the terms of the GNU Lesser General Public License as published by # the Free Software Foundation; either version 2.1 of the License, or (at # your option) any later version. # # This library is distributed in the hope that it will be useful, but # WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
