It seems that after an eclipse restart everything works well, both .byte and .native can be run as executable directly. Never mind my first message.

So far I'm using OcaIDE+ocamlbuild but I've got an issue with .byte and .native files. With some easy magic I can run them, but with a .byte.exe extension it will be straightforward for students. Does anyone know if there's a way to do this from ocamlbuild options ? I'd rather like not to add copy or steps. Marc de Falco
