# 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 licensed
|
|
# under LGPLv2.1+.
