# Additional tests to run before releasing a package.
#
# Run like:
# make PACKAGE=/path/to/protobuf-VERSION.tar.gz
#
# Some of these tests require tools or make assumptions that may not be
# available on end-user machines, so these cannot be part of "make check". For
# example, we test that the headers compile with strict warning settings, but
# since different compilers produce wildly different warnings we cannot assume
# that this test will pass everywhere. If we ran it as part of "make check",
# it could unnecessarily block users from running the real tests just because
# their compiler produces some extra warnings that probably aren't a big deal.
# So we run it separately.

clean:
rm -rf src target header_warning_test.cc header_warning_test.o header_warning_test
# Unpack the package into src, then install it into target.
