+To build iceoryx as 32-bit library, the following packages need to be installed additionally:
+
+```bash
+sudo dpkg --add-architecture i386
+sudo apt install libacl1-dev:i386 libc6-dev-i386 libc6-dev-i386-cross libstdc++6-i386-cross gcc-multilib g++-multilib
+```

 Additionally, there is an optional dependency to the [cpptoml](https://github.com/skystrife/cpptoml) library, which is used to parse the RouDi config file containing mempool configuration.
