Getting Started

Requirements

This project uses a fork of Embedded Artistry's standard CMake build system which is included here as the submodule cmake.

At a minimum you will need:

• git-lfs, which is used to store binary files in this repository
• CMake is the build system
• Some kind of compiler for your target system.
  • This repository has been tested with:
    • gcc-7, gcc-8, gcc-9
    • arm-none-eabi-gcc
    • Apple clang
    • Mainline clang

git-lfs

This project stores some files using git-lfs.

To install git-lfs on Linux:

sudo apt install git-lfs

To install git-lfs on OS X:

brew install git-lfs

Additional installation instructions can be found on the git-lfs website.

CMake Build System

The official way to install CMake is to use the pre-compiled binaries and installers on the CMake download page. You can also compile CMake from source. CMake can also be installed through popular package managers, although they may be slightly behind the latest release available on the website.

You can install CMake with apt on Linux/WSL:

sudo apt-get install cmake

Note: Does this not work? You may need to add an apt repository.

OS X users can install CMake using Homebrew:

brew install cmake

You can also use Python's pip to install CMake:

$ pip3 install cmake

Make is the default backend for CMake, but our Makefile interface defaults to Ninja. Ninja is similar in purpose to Make, but provides better performance.

To install Ninja on Linux & WSL:

$ sudo apt install ninja-build

To install on OSX:

$ brew install ninja

Getting the Source

This project uses git-lfs, so please install it before cloning. If you cloned prior to installing git-lfs, simply run git lfs pull after installation.

This project is hosted on GitHub. You can clone the project directly using this command:

git clone --recursive [email protected]:daleonpz/cmake-template.git

If you don't clone recursively, be sure to run the following command in the repository or your build will fail:

git submodule update --init

Building

If Make is installed, the library can be built by issuing the following command:

make

This will build all targets for your current architecture.

You can clean builds using:

make clean

You can eliminate the generated buildresults folder using:

make distclean

You can also use CMake directly for compiling.

Create a build output folder:

cmake -B buildresults

And build all targets by running

ninja -C buildresults

Cross-compilation is handled using CMake toolchain files. Example files are included in the cmake/toolchains/cross folder. You can write your own cross files for your specific processor by defining the toolchain, compilation flags, and linker flags. These settings will be used to compile the project.

Cross-compilation must be configured using the CMake command when creating the build output folder. For example:

cmake -B buildresults -DCMAKE_TOOLCHAIN_FILE=cmake/toolchains/cross/cortex-m3.cmake

Following that, you can run make (at the project root) or ninja to build the project.

Tests will not be cross-compiled. They will only be built for the native platform.

Testing

The tests for this project are written in CMocka and Catch, which are included as external dependencies and does not need to be installed on your system. You can run the tests by issuing the following command:

make test

By default, test results are generated for use by the CI server and are formatted in JUnit XML. The test results XML files can be found in buildresults/test/.

Documentation

Documentation can be built locally by running the following command:

make docs

Documentation can be found in buildresults/docs, and the root page is index.html.
