# Build the re2 library.
# First, build the re2 library.
# N.B., we don't follow the standard incantation for building re2
# (i.e., `make && make test && make install && make testinstall`),
# because some of the targets doesn't use $CXXFLAGS properly, which
# causes compilation to fail. The obj/libre2.a target is all we
# really need for our fuzzer, so that's all we build. Hopefully
# this won't cause the fuzzer to fail erroneously due to not running
# upstream's tests first to be sure things compiled correctly.
_try make clean
# We don't make everything, since one of the targets doesn't use $CXXFLAGS
# properly, which causes problems compiling. This target is all we really
# need for our fuzzer.
_try make obj/libre2.a
# TODO(wrengr): the test target has the same issue as the all target did.
_try make test
_try make install
_try make testinstall
# Build our fuzzers
# Second, build our fuzzers.
