Does anyone know where I can find a version of GCC/G++ compiler for Linux that will cross-compile for AROS?

ZeroHero used to provide one, but his website is down, and no-one seems to have saved his AROS (nor MorphOS) versions:

Hi Chris,

Good to see you around again. I am not sure if that is available anymore but I do have a copy of the old AmidevCPP which was the full IDE with Amiga and AROS libraries for cross compiling but from Windows. I can send you that if you are interested.

I still have a copy of AmiDevCpp, but I am looking for a Linux-based cross-compiler, and really one that can be scripted easily.

Sorry to go out of topic but are there any news about PortablE development?

Do you mind sharing?

@pixie:
Although your question is about AMIDev, chris did create a AROS cross compiler package and posted it on his website, see his post here.

But, the "normal" way of creating a cross compiler would be by following the instructions on deadwoods github page. That builds an AROS cross compiler for you (though it requires some work if you want to make it truly 'standalone' ). No windows instructions though but with WSL (or MSYS/others) that should not be a problem.
