General Structure

HelloWorld

Here is a diagram representing the structure of our Hello World:

In this application, we have a module called SayHello containing three files:

• a header (.h),
• a source file (.cc),
• a file containing the dataset options (.axl).

And outside the module, we have four files:

• a main.cc file allowing us to run our application,
• a CMakeLists.txt file allowing us to compile our application,
• a .config file allowing us to configure our application,
• a .arc file containing a dataset for our application.

All these elements constitute our HelloWorld application.

Note

It is possible to generate an application template using the arcane-template program. To generate a template for our HelloWorld using arcane-template, here is the command:

./arcane_templates generate-application -code-name HelloWorld --module-name SayHello --output-directory ~/HelloWorld

This program can be found in the bin folder of the Arcane installation directory: arcane_install/bin/.

In the following section, we will look at the SayHello module.
