So I was curious to start using the libFuzzer, but trying to follow along I
got the following error:
clang++ -fsanitize=address -fsanitize-coverage=edge test_fuzzer.cc Fuzzer*.o
Undefined symbols for architecture x86_64:
"_dfsan_create_label", referenced from:
fuzzer::TraceState::DFSanCmpCallback(unsigned long, unsigned long,
unsigned long, unsigned long long, unsigned long long, unsigned short,
unsigned short) in FuzzerTraceState.o
fuzzer::Fuzzer::InitializeTraceState() in FuzzerTraceState.o
"_dfsan_get_label_info", referenced from:
fuzzer::TraceState::GetLabelRange(unsigned short) in
FuzzerTraceState.o
"_dfsan_read_label", referenced from:
_dfsan_weak_hook_memcmp in FuzzerTraceState.o
"_dfsan_set_label", referenced from:
fuzzer::Fuzzer::InitializeTraceState() in FuzzerTraceState.o
ld: symbol(s) not found for architecture x86_64
clang-3.7: error: linker command failed with exit code 1 (use -v to see
invocation)
Any hints as to what I'm doing wrong? Thanks
