Hello World C-project

This is just a "helloworld" example project.

The only purpose of this project is to use as a scaffolding C language project.

The project uses CMakes to build the executable, and CHEAT for unit testing, that is downloaded from a remote repository the first time the project tests are built. It also has a workflow configured to build and run the tests on GitHub Actions automatically on each push of code.

Build and execute

1. From the source directory, generate the "Makefile":

   $ cmake .
   

2. Make the project and generate the executable "helloworld".

   $ make
   

3. Then execute with:

   $ out/helloworld
   

4. To install the executable helloworld into /usr/local/bin:

   $ sudo make install
   

   To install into another folder, execute the step 1 overwriting the CMAKE_INSTALL_PREFIX variable, eg. to install into /usr/bin folder:

   $ cmake -DCMAKE_INSTALL_PREFIX=/usr .
   

To clean the compiled binaries and compiled modules:

$ make clean

To clean all compiled files and generated "Makefiles":

$ make clean-all

Tests

Tests are built with CHEAT, a unit testing framework for C/C++.

All of them can be executed with CMake CTest:

$ make test

Or just:

$ ctest

To run the tests and see all the output in the console (specially if the tests fail), first build the project (make), and then execute:

$ out/test_say_hello
