| # 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 |
| ``` |
