| 5 | +# SYNOPSIS |
| 6 | +# |
| 7 | +# AX_CODE_COVERAGE() |
| 8 | +# |
| 9 | +# DESCRIPTION |
| 10 | +# |
| 11 | +# Defines CODE_COVERAGE_CPPFLAGS, CODE_COVERAGE_CFLAGS, |
| 12 | +# CODE_COVERAGE_CXXFLAGS and CODE_COVERAGE_LDFLAGS which should be |
| 13 | +# included in the CPPFLAGS, CFLAGS CXXFLAGS and LIBS/LDFLAGS variables of |
| 14 | +# every build target (program or library) which should be built with code |
| 15 | +# coverage support. Also defines CODE_COVERAGE_RULES which should be |
| 16 | +# substituted in your Makefile; and $enable_code_coverage which can be |
| 17 | +# used in subsequent configure output. CODE_COVERAGE_ENABLED is defined |
| 18 | +# and substituted, and corresponds to the value of the |
| 19 | +# --enable-code-coverage option, which defaults to being disabled. |
| 20 | +# |
| 21 | +# Test also for gcov program and create GCOV variable that could be |
| 22 | +# substituted. |
| 23 | +# |
| 24 | +# Note that all optimisation flags in CFLAGS must be disabled when code |
| 25 | +# coverage is enabled. |
| 26 | +# |
| 27 | +# Usage example: |
| 28 | +# |
| 29 | +# configure.ac: |
| 30 | +# |
| 31 | +# AX_CODE_COVERAGE |
| 32 | +# |
| 33 | +# Makefile.am: |
| 34 | +# |
| 35 | +# @CODE_COVERAGE_RULES@ |
| 36 | +# my_program_LIBS = ... $(CODE_COVERAGE_LDFLAGS) ... |
| 37 | +# my_program_CPPFLAGS = ... $(CODE_COVERAGE_CPPFLAGS) ... |
| 38 | +# my_program_CFLAGS = ... $(CODE_COVERAGE_CFLAGS) ... |
| 39 | +# my_program_CXXFLAGS = ... $(CODE_COVERAGE_CXXFLAGS) ... |
| 40 | +# |
| 41 | +# This results in a "check-code-coverage" rule being added to any |
| 42 | +# Makefile.am which includes "@CODE_COVERAGE_RULES@" (assuming the module |
| 43 | +# has been configured with --enable-code-coverage). Running `make |
| 44 | +# check-code-coverage` in that directory will run the module's test suite |
| 45 | +# (`make check`) and build a code coverage report detailing the code which |
| 46 | +# was touched, then print the URI for the report. |
| 47 | +# |
| 48 | +# This code was derived from Makefile.decl in GLib, originally licenced |
| 49 | +# under LGPLv2.1+. |
