Hi,
I've just created a vagrant environment to use for AmigaOS4 cross compiling development. You can use it on any OS that has Vagrant (Linux, Windows and MacOS).
What is it?
* Virtual Linux environment with pre-installed AmigaOS 4 PowerPC compiler (gcc 5.5.0) and latest official SDK.
* Scripts to download SDK dependencies from third party source (f.i. os4depot) with distributed instructions.
