This library provides the primary interface to uProtocol for uEntity applications. The primary point of interaction for most applications will be the layer 2 "communications" objects.

In addition to up-cpp, a uEntity will also need at least on transport implementation, such as up-transport-zenoh-cpp.

IMPORTANT NOTE: This project is under active development

• Compiler: GCC/G++ 11 or Clang 13
• Conan : 1.59 or latest 2.x

Using the recipes found in up-conan-recipes, build these Conan packages:

1. up-core-api: conan create --version 1.6.0-alpha4 --build=missing up-core-api/release

NOTE: all conan commands in this document use Conan 2.x syntax. Please adjust accordingly when using Conan 1.x.

To add up-cpp to your conan build dependencies, place following in your conanfile.txt:

[requires]
up-cpp/[~1.0]

[generators]
CMakeDeps
CMakeToolchain

[layout]
cmake_layout

NOTE: If using conan version 1.59 Ensure that the conan profile is configured to use ABI 11 (libstdc++11: New ABI) standards according to the Conan documentation for managing gcc ABIs.

The following steps are only required for developers to locally build and test up-cpp, If you are making a project that uses up-cpp, follow the steps in the How to Use the Library section above.

From the root of this repo, run:

conan install --build=missing .
cmake --preset conan-release
cd build/Release
cmake --build . -- -j

Once the build completes, tests can be run with ctest.

Debug builds can be generated by changing those steps to:

conan install --build=missing --settings=build_type=Debug .
cmake --preset conan-debug
cd build/Debug
cmake --build . -- -j

Before building up-cpp we need to build all dependencies from up-conan-recipes:

Please follow instruction for QNX build in file up-conan-recipes/README.md

Pre-requisite:

• Build and install all QNX build dependencies from up-conan-recipes
  • https://github.com/eclipse-uprotocol/up-conan-recipes

# setup path to up-conan-recipes
export QNX_CONAN_ROOT=<path_to_up-conan-recipes>

# Install conan toolchain for QNX target
#
# <profile-name>: nto-7.1-aarch64-le, nto-7.1-x86_64, nto-8.0-aarch64-le, nto-8.0-x86_64
# <version-number>: 1.0.0-rc0, 1.0.0, 1.0.1-rc1, 1.0.1
#
conan install -pr:h=$QNX_CONAN_ROOT/tools/profiles/<profile-name> --version=<version-number> --build=missing .

cmake --preset conan-release

cmake --build build/Release -- -j

# all tests you can find under build/Release/bin/
# copy test binaries to your QNX target

To get code coverage, perform the steps above, but replace cmake --preset... with

cd build/Release
cmake ../../ -DCMAKE_TOOLCHAIN_FILE=generators/conan_toolchain.cmake -DCMAKE_BUILD_TYPE=Coverage

Once the tests complete, the Unit Test Coverage report can be generated from the base up-cpp folder with: ./Coverage.sh

./coverage.sh

TODO Verify steps for pure cmake build without Conan.
