Installing

Prebuilt packages are published for every supported language, so most users never need to compile anything.

Building from source

Prerequisites are listed in the Build Guide. All commands are run from the root of the repository.

The C target builds both the shared and the static library in a single run. Each output directory also contains an include folder with the headers to add to your project.

The Rust bindings do not build the native library: the ntgcalls-sys build script downloads the matching static libraries from the GitHub release for your platform. Set NTGCALLS_RELEASE_BASE to build against a local release instead.

[!WARNING] Static linking for Windows is not supported yet since our library is built with MSVC and Go uses MinGW for static linking. More info can be found here

Go consumes the C bindings through an example project in ./examples/go/:

1. Download the shared or static release from the Releases page
2. Copy ntgcalls.h into ./examples/go/ntgcalls/
3. Copy the remaining files into ./examples/go/
   • ntgcalls.dll or ntgcalls.lib on Windows amd64
   • libntgcalls.so or libntgcalls.a on Linux amd64
   • libntgcalls.dylib or libntgcalls.a on macOS
4. Run go build or go run . with CGO_ENABLED=1
   • $env:CGO_ENABLED=1; go run . on Windows PowerShell
   • CGO_ENABLED=1 go run . on UNIX
