+#### Troubleshooting: Bindgen
+
+Retina uses [bindgen](https://docs.rs/bindgen/latest/bindgen/) to generate bindings to DPDK functions implemented in C. As of 06/2024, we have encountered issues when using bindgen with clang/llvm >13, apparently due to introduced APIs for SIMD intrinsics.
+
+If you are using clang and building Retina fails with an error such as the below, downgrade clang/llvm to <=13.
+
+```sh
+error: invalid conversion between vector type '__m128i' (vector of 2 'long long' values) and integer type 'int' of different size
+```

 ## Testing Retina (Offline) on a VM
 
 We have deployed Retina in offline mode (streaming pcaps) on both ARM- and x86-based Ubuntu VMs. This can be useful for getting started, development, and functional testing.
