# 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. |
|
# |
