Demonstration Project for CI

Requirements

• CMake Minimum Version 3.10)
• gcc+ ( require gcc 10.1 or higher).

Quick start

this is a demonstration project for C++ 23, make and CI ,

cmake -S ./ -B build
cmake --build build -j 2 -v  
cmake  --install ../bin

This will make a build directory (-B) if it does not exist, with the source directory defined as -S. CMake will configure and generate makefiles by default, as well as set all options to their default settings and cache them into a file called CMakeCache.txt, which will sit in the build directory. You can call the build directory anything you want; by convention it should have the word build in it to be ignored by most package’s .gitignore files.

You can then invoke your build system (line 2). You can add '-j 2' to build on two cores, or '-v' to verbosely show commands used to build.

Finally, you can even run your tests from here, by passing the 'Factorial_tst' target to the underlying build system. '-t' lets you select a target. There’s also a cmake

--install command in CMake 3.15+ that does the install - without invoking the underlying build system!

to run the executable use the command below in the build directory. Here we are providing the argument of 7 to get the factorial of it.

./build/bin/calcFactorial 7

Output should be:

The factorial of 7 = 5040

to runtests we call build and tests

``bash

cmake --build build ; ./build/test/bin/Factorial_tst
