neoAPI C# Wrapper Generation for Linux

This project provides tools to generate a C# wrapper for the Baumer neoAPI SDK on Linux using SWIG.

Prerequisites

• SWIG: Simplified Wrapper and Interface Generator (sudo apt install swig)
• g++: GNU C++ compiler
• Baumer neoAPI SDK: The SDK directory (e.g., Baumer_neoAPI_1.5.0_lin_x86_64_cpp) should be present or its path provided to the build script.

Step-by-Step Generation

1. Generate the SWIG Interface

Run the generate_interface.sh script to create the neoapi.i file. This script automatically adds ergonomic C# properties (like SerialNumber, ModelName, etc.) to the CamInfo class to match the Windows neoAPI implementation.

./generate_interface.sh [path_to_sdk]

2. Build the Wrapper

Run the build_wrapper.sh script to generate the C# source and the native shared library.

./build_wrapper.sh [path_to_sdk]

This will produce:

• wrapper/neoAPI_linux.cs: Consolidated C# wrapper classes.
• wrapper/libneoapi_csharp.so: Native library required for runtime.

Project Structure

• generate_interface.sh: Script to generate the SWIG interface file (neoapi.i).
• build_wrapper.sh: Script to run SWIG and compile the native wrapper library.
• neoapi.i: The SWIG interface definition.
• wrapper/: Directory containing the generated output and native library dependencies.
• .gitignore: Configured to ignore intermediate build artifacts and native libraries.

Troubleshooting

• SDK Path: If the SDK is not in the default directory, ensure you provide the absolute path as an argument to the scripts.
• RPath: The generated native library uses $ORIGIN and $ORIGIN/lib in its RPath to find the neoAPI C++ libraries. Ensure the required .so files are available in the wrapper/lib directory.
