# How to build this example ?
2+
3+
This example is intended to be compiled with [Codelite](https://codelite.org).
4+
5+
[Codelite](https://codelite.org) is a free cross-platform software...
6+
7+
If you want to compile it without codelite, you can do it with [GNU make](https://www.gnu.org/software/make/) :
8+
9+
$ make -f read-input-registers.mk
10+
11+
Nevertheless, i am not sure that it works on Windows™ and macOS™.
12+
13+
You can then run the program that is in the Debug folder.
