Re: Make "make check" abort on memory leaks or errors

[Bob Friesenhahn]

For GraphicsMagick I added a 'memcheck' target which performs 'make 
check' under valgrind.  This requires that subordinate test scripts 
will prefix test executable invokations with $MEMCHECK and that any 
necessary valgrind suppressions exist in order to allow the tests to 
succeed when there are no problems.  Normally Automake tests run to 
completion and report the tests which have failed rather than 
immediately 'aborting' the tests.  The valgrind reports can then be 
found in a test log file.

# memcheck: valgrind's memory access checker.
# The suppressions which come with valgrind are usually insufficient
# to handle certain pthread library aspects and gomp and so errors
# will be reported which are unrelated to GraphicsMagick.  When first
# starting with a new system (or after a major system update), it is
# good to execute the test suite like 'make memcheck
# VALGRIND_EXTRA_OPTS=--gen-suppressions=all' to create valgrind
# suppression entries in the test log.  Tell valgrind about the
# suppressions by creating a .valgrindrc file with content like:
#   --memcheck:suppressions=mysupp.supp
memcheck:
        $(MAKE) MEMCHECK='valgrind --tool=memcheck --leak-check=full 
--read-var-info=yes \
        --error-exitcode=2 --track-origins=yes --num-callers=12 \
        --quiet $(VALGRIND_EXTRA_OPTS)' check
