| # First, build RE2. |
| # 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. |
