Starting Development in AROS

[falemagn]

If you don't want to integrate your code into the AROS CVS (yet), all you need to do is set up a crosscompiler. In order to do that you can compile AROS itself, in which case the crosscompiler (a fake one, but which does the right job) is automatically set up for you under the

Code: [Select]


bin/linux-i386/tools/i386-linux/


directory, within the toplevel AROS source dir.

There you'll find i386-aros-gcc, i386-aros-ld and so on which you can use to make your own programs runnable under AROS.

Hope that helps.

I'm need to set up the development environment so that I can write utilities for AROS.

Yes, and what I told you applies perfectly well to your case: you said you aready have the AROS sources, so the fastest way for you to get ready is to compile those sources and get the (fake) crosscompiler from where I told you.

Alternatively, you can download the linux binary from the download page, and from there also download the SDK package. You'll unpack the SDK package somewhere, run the installation script in it and it will automatically set up for you the (fake) crosscompiler.

Any ideas?

Yup, I forgot to add the -static flag to the line where the real gcc is invoked. I fixed this in the CVS, so tonight's build should be fine, but you can simply open the i386-aros-gcc file and add -static at the end of the command line it contains. Tell me if that works.

However I'm now having a problem compiling the Zune "Hello World" example from AROS' website. The error I get is:

There are undefined symbols in 'hello':
U MUI_MakeObject
U MUI_NewObject

That's because those functions are in the libmui.a library, so you need to append -lmui at the end of the command line which you use to produce the executable. If this is not mentioned in the example, then there's a bug in the documentation.

However, you could avoid linking with that library if you do this

Code: [Select]


    #define MUIMASTER_YES_INLINE_STDARG


before including any header file related to Zune/MUI.

Thanks again falemagn, I'm starting to think you know this stuff

Well, I better do, as I'm one of the AROS developers ;-)

I'm not very familiar with the AmigaOS API (most of my programming has been in Windows and Linux). What would you recommend as a resource? I was thinking of buying a copy of the Amiga Development CD.

That's certainly a good idea, yes.
