+## Cross compilation
+
+### GNU/Linux
+
+It is assumed that your are currently using a GNU/Linux distribution, so the default `linux-compiler` is `g++` found in the environment.
+
+### Windows
+
+You need the cross-compiler `i686-w64-mingw32-g++-win32`, you can install it in Debian :
+
+```sh
+sudo apt install g++-mingw-w64-i686
+```
