dss_adcs

\cond \endcond

dss_adcs is a template for a simple CMake-based C++ project: it can be used as the basis for new projects. An example CMake module is available to make it easy to include your project in other projects (should be customized): Finddss_adcs.cmake.

(N.B. remember to change all instances of dss_adcs to your new project name!).

Features

• General directory structure common to C++ projects
• Example of CMake module Finddss_adcs.cmake
• Testing framework (Catch)
• Install script (make install)
• CPack script for packaging (make package)
• Automatic API documentation (Doxygen)
• Continuous Integration (Travis CI)
• Code coverage analysis (Coveralls) (make coverage)
• Example of how to include external dependencies (using ExternalProject module)
• Separate file to specify location of project files (ProjectFiles.cmake)

Requirements

To install this project, please ensure that you have installed the following (install guides are provided on the respective websites):

• Git
• A C++ compiler, e.g., GCC, clang, MinGW
• CMake
• Doxygen (optional)
• Gcov (optional)
• LCOV (optional)

The following dependency is optional (see Build options):

• CATCH (unit testing library necessary for BUILD_TESTS build option)

This dependency will be downloaded and configured automagically if not already present locally (requires an internet connection).

Installation

Run the following commands to download, build, and install this project. Substitute project_name with the name of your project (if you leave it out, the repository will be cloned to a local folder called dss_adcs). This will customize the project targets for you. Note that project_name must not contain spaces! The --depth 1 parameter passed to git clone ensures that the git history is not downloaded. In case you would like to preserve the history of this project, omit that option.

git clone https://www.github.com/kartikkumar/dss_adcs --depth 1 <project_name>
cd <project_name>
git submodule init && git submodule update
mkdir build && cd build
cmake -DPROJECT_NAME=<project_name> .. && cmake --build .

To push this project to your own remote repository, you can run the following command, which will overcome the issues with utilizing a shallow clone:

git commit --amend .

This rewrites the last commit and ensures that you can then push the repository to a remote (e.g., Github, BitBucket, Gitlab, etc.).

To install the header files, run the following from within the build directory:

make install

Note that dependencies are installed by fetching them online, in case they cannot be detected on your local system. If the build process fails, check the error log given. Typically, building fails due to timeout. Simply run the cmake --build . command once more.

Build options

You can pass the following, general command-line options when running CMake:

• -DPROJECT_SUMMARY: set short string summary for your project
• -DPROJECT_VENDOR_NAME: set short string name for vendor of your project
• -DPROJECT_VENDOR_CONTACT: set short string email address for vendor of your project
• -DCMAKE_INSTALL_PREFIX[=$install_dir]: set path prefix for install script (make install); if not set, defaults to usual locations
• -DBUILD_SHARED_LIBS=[ON|OFF (default)]: build shared libraries instead of static
• -DBUILD_MAIN[=ON|OFF (default)]: build the main-function
• -DBUILD_DOXYGEN_DOCS[=ON|OFF (default)]: build the Doxygen documentation (LaTeX must be installed with amsmath package)
• -DBUILD_TESTS[=ON|OFF (default)]: build tests (execute tests from build-directory using ctest -V)
• -DBUILD_DEPENDENCIES[=ON|OFF (default)]: force local build of dependencies, instead of first searching system-wide using find_package()

The following command is conditional and can only be set if BUILD_TESTS = ON:

• -DBUILD_COVERAGE_ANALYSIS[=ON|OFF (default)]: build code coverage using Gcov and LCOV (both must be installed; requires GCC compiler; execute coverage analysis from build-directory using make coverage)

Pass these options either directly to the cmake .. command, e.g., to build the tests:

cmake -DPROJECT_NAME=<project_name> -DBUILD_TESTS=on ..

N.B.: Toggling options to build tests using ccmake does not work correctly, as the necessarily libraries are not downloaded automagically!

Project structure

This project has been set up with a specific file/folder structure in mind. The following describes some important features of this setup:

• cmake/Modules : Contains CMake modules
• docs: Contains project-specific docs in Markdown that are also parsed by Doxygen. This sub-directory includes global_todo.md, which contains a global list of TODO items for project that appear on TODO list generated in Doxygen documentation
• doxydocs: HTML output generated by building Doxygen documentation
• include: Project header files (*.hpp)
• scripts: Shell scripts used in Travis CI build
• src: Project source files (*.cpp), including main.cpp, which contains example main-function for project build
• test: Project test source files (*.cpp) that are provided to the Catch framework
• .travis.yml: Configuration file for Travis CI build, including static analysis using Coverity Scan and code coverage using Coveralls
• CMakeLists.txt: main CMakelists.txt file for project (should not need to be modified for basic build)
• Dependencies.cmake: list of dependencies and automated build, triggered if dependency cannot be found locally
• Doxyfile.in: Doxygen configuration file, adapted for generic use within project build (should not need to be modified)
• LICENSE.md: license file for project (copyright statement needs to be edited)
• ProjectFiles.cmake: list of project source files to build
• README.md: project readme file, parsed as main page for Doxygen documentation
