# of the make output, so that the user could no longer see information

# $(VALGRIND) is still there to be able to use a wrapper such as valgrind

# is generated, use LOG_COMPILER instead. For additional information, see:
# https://www.gnu.org/software/automake/manual/automake.html#Parallel-Test-Harness
#
# Note: We do not use "env -u DISPLAY" as the -u option is a GNU extension
# and not supported by NetBSD. Setting DISPLAY='' is not equivalent, but
# it also avoids the bogus "Invalid MIT-MAGIC-COOKIE-1 key" error message
# that can make the parsing of the output fail.

# The -no-install option prevents libtool from generating wrapper scripts
# for the tests.
# This is useful to easily run individual test scripts under valgrind or gdb.

# The -L$(top_builddir)/src/.libs option is necessary for some platforms,
# such as HP-UX, when --with-gmp or --with-gmp-lib is used and an old MPFR
# library is already installed in the corresponding lib directory: its
# purpose is to make sure that the local .libs comes first in the library
# search path (otherwise the tests are linked against the old MPFR library
# by the LINK command -- see the generated Makefile). See:
