Building and running demo app

Building demo app

There are multiple directories, all containing same app but different way of getting dependencies

01_system: Relies on a system package manager

mkdir build && cd build
cmake ..  -DCMAKE_BUILD_TYPE=Debug
make

02_docker: Relies on Docker

docker build -t hello_cpp_serbia .
docker run hello_cpp_serbia
# You will probably need to stop it
docker stop $(docker ps -a -q  --filter ancestor=hello_cpp_serbia)

03_conan: Relies on the Conan package manager

mkdir build 
cd build
cmake .. -DCMAKE_BUILD_TYPE=Debug
make

04_nix-shell: Relies on the Nix package manager

nix-shell
mkdir build 
cd build
cmake .. -DCMAKE_BUILD_TYPE=Debug
make

05_nix: Relies on the Nix package manager

nix-build
./result/bin/hello_cpp_serbia ../OpenSans-Regular.ttf

Running demo app

App requires one argument (ttf font) which will be used when rendering the message.

Specify relative path to ./OpenSans-Regular.ttf as a first argument, depending on where are you calling app from.

./result/bin/hello_cpp_serbia <REPO_ROOT>/OpenSans-Regular.ttf
