# SYNOPSIS
|
|
#
|
|
# AX_VALGRIND_CHECK()
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Checks whether Valgrind is present and, if so, allows running `make
|
|
# check` under a variety of Valgrind tools to check for memory and
|
|
# threading errors.
|
|
#
|
|
# Defines VALGRIND_CHECK_RULES which should be substituted in your
|
|
# Makefile; and $enable_valgrind which can be used in subsequent configure
|
|
# output. 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.
