VALGRIND_ENABLED is defined and substituted, and corresponds to +# the value of the --enable-valgrind option, which defaults to being +# enabled if Valgrind is installed and disabled otherwise. +# +# If unit tests are written using a shell script and automake's +# LOG_COMPILER system, the $(VALGRIND) variable can be used within the +# shell scripts to enable Valgrind, as described here: +# +# https://www.gnu.org/software/gnulib/manual/html_node/Running-self_002dtests-under-valgrind.html +# +# Usage example: +# +# configure.ac: +# +# AX_VALGRIND_CHECK +# +# Makefile.am: +# +# @VALGRIND_CHECK_RULES@ +# VALGRIND_SUPPRESSIONS_FILES = my-project.supp +# EXTRA_DIST = my-project.supp +# +# This results in a "check-valgrind" rule being added to any Makefile.am +# which includes "@VALGRIND_CHECK_RULES@" (assuming the module has been +# configured with --enable-valgrind). Running `make check-valgrind` in +# that directory will run the module's test suite (`make check`) once for +# each of the available Valgrind tools (out of memcheck, helgrind, drd and +# sgcheck), and will output results to test-suite-$toolname.log for each. +# The target will succeed if there are zero errors and fail otherwise. +# +# The macro supports running with and without libtool. +# +# LICENSE +# +# Copyright (c) 2014, 2015 Philip Withnall <[email protected]> +# +# Copying and distribution of this file, with or without modification, are +# permitted in any medium without royalty provided the copyright notice +# and this notice are preserved.
