17 **Note**: To enable position independent and multi-symbol DataMatrix detection, the library needs to be compiled with a c++20 compiler. Unfortunately some build environments (currently the 32-bit builds for Linux) used by `cibuildwheel` to generate the binary wheels that are published on [pypi.org](https://pypi.org/project/zxing-cpp/) don't include a c++20 compiler. Best chance to enable proper DataMatrix support in that case is by installing from source: |

23 In that case or if there is no pre-build wheel available for your platform or python version or if you use `setup.py` directly, a suitable [build environment](https://github.com/zxing-cpp/zxing-cpp#build-instructions) including a c++ compiler is required. |
