No...he said that the standard windows port would come first. Then the Mac and Linux versions would come sometime later.

There's no such thing as a program that's compiled to work with all OSes. A program is compiled to work with a specific OS, among other things such as a CPU family.

The Linux and Mac versions will each have to be compiled separately.

This brings another question...Stefan will have to decide whether to just release the source for the linux version or to use a binary package like RPM. If he uses RPM, people using Gentoo aren't gonna be too happy, namely Loriel. Releasing it as source code poses some problems since Graal is closed source. For you non-linux users, linux doesn't just use installation shield programs like windows and macOS does.

BTW, C++, not C.
