# Running the fuzzers locally There is a [helper script](build.sh) to build the fuzzers, which has only been tested on Debian and Ubuntu linux so far. There should be no problems fuzzing on Windows (using clang>=8) or on Mac, but the script will probably not work out of the box. Something along ```sh mkdir build cd build export CXX=clang++ export CXXFLAGS="-fsanitize=fuzzer-no-link -DFUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION= -g" cmake .. -DFMT_SAFE_DURATION_CAST=On -DFMT_FUZZ=On -DFMT_FUZZ_LINKMAIN=Off -DFMT_FUZZ_LDFLAGS="-fsanitize=fuzzer" cmake --build . ``` should work to build the fuzzers for all platforms which clang supports. Execute a fuzzer with for instance ```sh cd build export UBSAN_OPTIONS=halt_on_error=1 mkdir out_chrono bin/fuzzer_chrono_duration out_chrono ```
