# =========================================================================== # 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 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.
