| # Simple example of a build file that nicely integrates a fuzz target |
| # with the rest of the project. |
| # |
| # We use 'make' as the build system, but these ideas are applicable |
| # to any other build system |
| |
| # By default, use our own standalone_fuzz_target_runner. |
| # This runner does no fuzzing, but simply executes the inputs |
| # provided via parameters. |
| # Run e.g. "make all LIB_FUZZING_ENGINE=/path/to/libFuzzer.a" |
| # to link the fuzzer(s) against a real fuzzing engine. |
| # |
| # OSS-Fuzz will define its own value for LIB_FUZZING_ENGINE. |
| LIB_FUZZING_ENGINE ?= standalone_fuzz_target_runner.o |
| |
| # Values for CC, CFLAGS, CXX, CXXFLAGS are provided by OSS-Fuzz. |
| # Outside of OSS-Fuzz use the ones you prefer or rely on the default values. |
| # Do not use the -fsanitize=* flags by default. |
| # OSS-Fuzz will use different -fsanitize=* flags for different builds (asan, ubsan, msan, ...) |
| |
| # You may add extra compiler flags like this: |
| CXXFLAGS += -std=c++11 |

| all: do_stuff_fuzzer |

| rm -fv *.a *.o *_fuzzer crash-* *.zip |

| # Fuzz target, links against $LIB_FUZZING_ENGINE, so that |
| # you may choose which fuzzing engine to use. |
