Also defines CODE_COVERAGE_RULES which should be +# substituted in your Makefile; 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: +# +# @CODE_COVERAGE_RULES@ +# my_program_LIBS = ... $(CODE_COVERAGE_LIBS) ... +# my_program_CPPFLAGS = ... $(CODE_COVERAGE_CPPFLAGS) ... +# my_program_CFLAGS = ... $(CODE_COVERAGE_CFLAGS) ... +# my_program_CXXFLAGS = ... $(CODE_COVERAGE_CXXFLAGS) ... +# +# This results in a "check-code-coverage" rule being added to any +# Makefile.am which includes "@CODE_COVERAGE_RULES@" (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. +# +# In earlier versions of this macro, CODE_COVERAGE_LDFLAGS was defined +# instead of CODE_COVERAGE_LIBS. They are both still defined, but use of +# CODE_COVERAGE_LIBS is preferred for clarity; CODE_COVERAGE_LDFLAGS is +# deprecated. They have the same value. +# +# This code was derived from Makefile.decl in GLib, originally licenced +# 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 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.
