AosCore cpp libraries

Prepare build environment

• Install conan:

pip install conan

• Install lcov (optional):

sudo apt install lcov

lcov is required to generate code coverage report. The version 2.0 or greater is required. If your Linux distributive doesn't contain the required version, download and install the required version manually. For example in Ubuntu 22.04 it can be installed as following:

wget https://launchpad.net/ubuntu/+source/lcov/2.0-4ubuntu2/+build/27959742/+files/lcov_2.0-4ubuntu2_all.deb
sudo dpkg -i lcov_2.0-4ubuntu2_all.deb

Build

To make a build, run the following command:

./build.sh build

It installs all external dependencies to conan, creates ./build directory, builds the AoCore components with unit tests and coverage calculation target. It is also possible to customize the build using different cmake options:

cd build/
conan install ../conan/ --output-folder . --settings=build_type=Debug --build=missing
cmake .. -DCMAKE_TOOLCHAIN_FILE=./conan_toolchain.cmake -DWITH_TEST=ON -DCMAKE_BUILD_TYPE=Debug

Cmake options:

Option	Value	Default	Description
WITH_TEST	ON, OFF	OFF	creates unit tests target
WITH_COVERAGE	ON, OFF	OFF	creates coverage calculation target
WITH_DOC	ON, OFF	OFF	creates documentation target

Cmake variables:

Variable	Description
CMAKE_BUILD_TYPE	Release, Debug, RelWithDebInfo, MinSizeRel
CMAKE_INSTALL_PREFIX	overrides default install path

Run unit tests

Build and run:

./build.sh test

Check coverage

lcov utility shall be installed on your host to run this target. See this chapter.

Build and run:

./build.sh coverage

The overall coverage rate will be displayed at the end of the coverage target output:

...
Overall coverage rate:
  lines......: 94.7% (72 of 76 lines)
  functions..: 100.0% (39 of 39 functions)

Detailed coverage information can be find by viewing ./coverage/index.html file in your browser.

Generate documentation

doxygen package should be installed before generation the documentations:

sudo apt install doxygen

Generate documentation:

./build.sh doc

The result documentation is located in build/doc folder. And it can be viewed by opening build/doc/html/index.html file in your browser.

Install libraries

The default install path can be overridden by setting CMAKE_INSTALL_PREFIX variable.

Configure example:

cd build/
cmake ../ -DCMAKE_INSTALL_PREFIX=/my/location

Install:

cd build/
make  install
