I’m currently building AROS from source. For what it’s worth, <tt>configure</tt> fails to detect if <tt>wget</tt> is missing, so the build process broke down pretty quickly.

Right now it’s running happily, though.

Out of curiosity, why on earth does AROS need gmp?

No, I downloaded the binaries, unzipped them into the directory I wanted, and I run from there. That’s what the website suggests.

if you have had built it yourself you could use the cross compilers, which are in crosstools, say, dependent on actual architecture somewhere like:
your dir/bin/linux-(your arch)/tools/crosstools

it would be something like
(your arch)-aros-gcc, c++, cpp or the like respectively.

Are these files in the AROS download, or something I install on Fedora? I know gcc includes some cross-compiling options but I don’t think that’s what you mean here; I get the impression you mean something that comes with the AROS source download, as you write a moment later:

Wait. There’s an ABI v2?!?!?

Let me put it thus: I would like to write programs for AROS, perhaps even contribute to things such as fixing a pointer issue I’ve encountered (which I suspect is easy to fix). I don’t really care much about the ABI, as I would be happy to work with open source. I would prefer to use C++, however, and I’d prefer to use a modern C++. I don’t have to, and obviously if I want to contribute to the system I imagine I’d be restricted to C, but I find C++11 is a much, much more flexible and reliable language than C, so I’d like to use it if I can.

Do I have to download the sources to do that and compile AROS from scratch? Would that make it work?

The ABi v1 sdk isn?t really in a usable state. The wrapper works for simple c stuff but not c++.

I just ran the SDK's installer script. GCC 7.x is what Fedora includes. If you want I?ll copy one of the resulting files here so you can see what it produced.

When im working on stuff for AROS, I do it inside the source tree (just add a "local" dir or something) and use the mmakefile.src's the build system uses.

I?m not sure why that should help but I?'ll try it. I didn?t use a makefile; I just ran

<pre style="margin-left:10%;margin-right:10%;"><tt>
g++ -o hello_cxx hello.cxx
</tt></pre>
The parallel to doing this in C worked fine so I thought, perhaps foolishly, it should work in C++, too.

AROS builds a lot of c++ stuff with no issue - so I suspect its something on your end thats wrong.

Oh, I do, too, after I investigated further. At first I had thought otherwise (& I admit I said so above) but not after.

It looks like you are trying to use Unicode features which we don?t really support (unlesss you do some ugly hacking/provide the Unicode functions).

It was a simple hello, world program. I?m away from my computer at the moment but it was along these lines:
<pre><tt>
#include <iostream>
using std::cout;

int main() {
cout << "Hello, world! (in c++)\n";
}
</tt></pre>

That?s it. This compiles when I use g++ in Linux proper; it failed only when I tried running it with the aros-gcc (or whatever it?s called).

Also if you are trying this stuff under ABI v0?

No, compiling in Linux for AROS hosted ABI v1; i.e., through the toolchain.
