4.2. Step - 00 : Installation of Cucumber for C/C++¶

The way we use Behave to run BDD tests with Python (BDD - Python), we use Cucumber CPP to run BDD Tests with C/C++

As a preparation step to play with BDD with C/C++, you will need to install few things up front.

Ruby
Bundler for Ruby:
```
gem install bundler
```

Packages to use Cucumber CPP on an Ubuntu System:

sudo apt-get install ruby-dev

sudo apt-get install libboost-all-dev

sudo apt-get install libgmock-dev

sudo apt-get install cmake-extras

Optionally, you can as well install:

sudo apt-get install qtbase5-dev

sudo apt-get install xvfb

4.2.1. Cucumber-CPP and it’s Ruby Dependencies.¶

Checkout the Cucumber-CPP first:

git clone https://github.com/cucumber/cucumber-cpp.git

Go to checkout directory, so that you can refer to Gem File:
```
cd cucumber-cpp
```
Install Dependencies. Do not run this as SUDO. Run as a normal command only:
```
bundle install
```

For future use, checkout sub modules:

git submodule init

git submodule update

On Ubuntu (and similar linux systems) install Cucumber-CPP: Go to checkout directory, to compile Cucumber-CPP with CMake:
```
cd cucumber-cpp

cmake -S . -B ../_cucumber-cpp_build
```

Optionally, you can just build without anything extra:

cd cucumber-cpp

cmake -S . -B \
      ../_cucumber-cpp_build_minimal \
      -DCUKE_USE_STATIC_BOOST=ON \
      -DCUKE_USE_STATIC_GTEST=ON \
      -DCUKE_ENABLE_BOOST_TEST=OFF \
      -DCUKE_ENABLE_EXAMPLES=OFF \
      -DCUKE_ENABLE_GTEST=OFF \
      -DCUKE_ENABLE_QT=OFF \
      -DCUKE_TESTS_E2E=OFF \
      -DCUKE_TESTS_UNIT=OFF \
      -DCUKE_TESTS_VALGRIND=OFF

cd ../_cucumber-cpp_build_minimal

make all -j

Install the cucumber libs with sudo into the system:
```
sudo make install -j
```
