# 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
|
||
|
|
```
