C++ with Meson

Install Meson and requirements

sudo apt install python3 python3-pip python3-setuptools python3-wheel ninja-build libgtk-3-dev

pip3 install --user meson ninja

Everything installed right you can configure and build the build system by running meson build. If the folder build already exists, you can run meson --reconfigure build to let meson run the configuration again and update the build folder. With the build folder existing, cd build and run ninja. Ninja will gather all dependencies and build every executable for you at once. All executables are then gathered in your build folder. In short summary:

meson builddir && cd builddir
meson compile
meson test

Hello World

We start with the most basic programm "Hello World". First create the C file which holds the source. Then create a Meson build description and write it in a file called meson.build. That's all we need. Build the application with the command:

meson setup builddir
cd builddir
meson compile

Once the executable is built it run:

./demo

Adding dependencies

More complex programms need dependencies and other files. The Meson file includes all instructions to find and use libraries, like GTK+:

project('tutorial', 'c')
gtkdep = dependency('gtk+-3.0')
executable('demo', 'main.c', dependencies : gtkdep)

To add multiple libraries, simply use seperate dependency() calls

gtkdeps = [dependency('gtk+-3.0'), dependency('gtksourceview-3.0')]
