Waku Go Bindings

Go bindings for the Waku library.

Install

go get -u github.com/logos-messaging/logos-messaging-go-bindings

Dependencies

This repository doesn't download or build logos-messaging-nim. You must provide libwaku and its headers.

To do so, you can:

• Build libwaku from https://github.com/logos-messaging/logos-messaging-nim.
• Point cgo to the headers and compiled library when building your project.

Example environment setup (adjust paths to your logos-messaging-nim checkout):

export LMN_DIR=/path/to/logos-messaging-nim
export CGO_CFLAGS="-I${LMN_DIR}/library"
export CGO_LDFLAGS="-L${LMN_DIR}/build -lwaku -Wl,-rpath,${LMN_DIR}/build"

Such setup would look like this in a Makefile:

LMN_DIR ?= /path/to/logos-messaging-nim
CGO_CFLAGS = -I$(LMN_DIR)/library
CGO_LDFLAGS = -L$(LMN_DIR)/build -lwaku -Wl,-rpath,$(LMN_DIR)/build

build: ## Your project build command
	go build ./...

For a reference integration, see how status-go wires CGO_CFLAGS and CGO_LDFLAGS in its build setup.

NOTE: If your project is itself used as a Go dependency, all its clients will have to follow the same logos-messaging-nim setup.

Development

When working on this repository itself, logos-messaging-nim is included as a git submodule for convenience.

• Initialize and update the submodule, then build libwaku

  git submodule update --init --recursive
  make -C waku build-libwaku

• Build the project. Submodule paths are used by default to find libwaku.

  make -C waku build
