Build from source

If you want to hack on ReBuzz or build your own binaries, clone the repository and open the solution in Visual Studio 2022.

1. Clone the repository

ReBuzz uses submodules, so make sure you clone with --recurse-submodules: 

git clone --recurse-submodules https://github.com/wasteddesign/ReBuzz.git
cd ReBuzz

2. Open the solution

  • Open ReBuzz/ReBuzz.sln in Visual Studio 2022 (Community is fine).
  • Ensure the ReBuzz project is set as the startup project (bold in Solution Explorer).
  • Build the solution (Debug or Release, x64).

Output will be placed under something like: bin/Debug/x64/net9.0-windows or bin/Release/x64/net9.0-windows, depending on the configuration.

Build layout notes

Intermediate files are kept under build/ to avoid polluting the source tree. This is configured via Directory.Build.props and custom IntermediateOutputPath/OutputPath entries in the project files.
