IOTA common library

This is a collection of libraries containing models, utils, and cryptography primitives used in IOTA. It's able to use in a Bazel or CMake project.

Build and test via Bazel

bazel build -- //... -//mobile/...
bazel test -- //... -//mobile/...

Use in a Bazel project

First you need to add org_iota_common to your Bazel project in the WORKSPACE file like this:

load("@bazel_tools//tools/build_defs/repo:git.bzl", "git_repository")

git_repository(
    name = "org_iota_common",
    commit = "6ef2af84950f56c8489623e9672c4ac882bb3961",
    remote = "https://github.com/iotaledger/iota_common.git",
)

git_repository(
    name = "rules_iota",
    commit = "49b2674474dedd77d46fddf75330ea7dcd23f0d3",
    remote = "https://github.com/iotaledger/rules_iota.git",
)

load("@rules_iota//:defs.bzl", "iota_common_external")
iota_common_external()

Then add it to dependencies in the BUILD file:

cc_binary(
    name = "my_app",
    srcs = ["my_app.c"],
    deps = [
        "@org_iota_common//common:errors",
        "@org_iota_common//common/model:transaction"],
)

Build and test via CMake

mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=. -DTRINARY_TEST=ON ..
make -j8 && make test

Use in a CMake project

Adds iota_common to your CMakeLists.txt like:

# The FetchContent module needs cmake 3.11 or above.
cmake_minimum_required(VERSION 3.11)

# fetch iota_common
include(FetchContent)
FetchContent_Declare(
  iota_common
  GIT_REPOSITORY https://github.com/iotaledger/iota_common.git
  GIT_TAG master # could be branch name, tag or commit hash.
)

if(${CMAKE_VERSION} VERSION_LESS 3.14)
    macro(FetchContent_MakeAvailable NAME)
        FetchContent_GetProperties(${NAME})
        if(NOT ${NAME}_POPULATED)
            FetchContent_Populate(${NAME})
            add_subdirectory(${${NAME}_SOURCE_DIR} ${${NAME}_BINARY_DIR})
        endif()
    endmacro()
endif()

message(STATUS "Fetching iota_common")
FetchContent_MakeAvailable(iota_common)
