# SYNOPSIS # # MY_CODE_COVERAGE() # # DESCRIPTION # # Defines CODE_COVERAGE_CFLAGS and CODE_COVERAGE_LDFLAGS which should be # included in the CFLAGS and LIBS/LDFLAGS 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. # # Usage example: # configure.ac: # MY_CODE_COVERAGE # # Makefile.am: # @CODE_COVERAGE_RULES@ # my_program_LIBS = … $(CODE_COVERAGE_LDFLAGS) … # my_program_CFLAGS = … $(CODE_COVERAGE_CFLAGS) … # # 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. # # LICENSE # # Copyright © 2012, 2014 Philip Withnall # Copyright © 2012 Xan Lopez # Copyright © 2012 Christian Persch # Copyright © 2012 Paolo Borelli # Copyright © 2012 Dan Winship # # Derived from Makefile.decl in GLib, originally licenced under LGPLv2.1+. # This file is licenced under LGPLv2.1+.
