clang with fuzzer support(-fsanitize=fuzzer. at least clang 8.0 should work)
Add apt source: https://apt.llvm.org/
$ sudo apt install clang++-11
$ sudo apt install libfuzzer-11-dev
Optionally, if you didn't set update-alternatives you can set clang++ to point to clang++11
$ sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-11 10
$ sudo update-alternatives --install /usr/bin/clang++ clang++ /usr/bin/clang++-11 10
Edit Makefile if required, then simply:
$ make
Increase memory limit. e.g. -rss_limit_mb=50000
$ ./fuzzer -rss_limit_mb=20000 -jobs 4
- Fuzzer for DNG writer.
