New on developing for the Amiga

Hi,

I want to start developing for the classic amiga, the one that runs Kickstart3.1 and respective Worbench3.1.

I set up a cross compiler (Vbcc) to target the amiga platform and can compile, link on the host system (macOSX) and run the software on FS-UAE emulator from a shell.

Now I need the Amiga SDK to be able to use Intuition etc. Does anyone know if these are freely available and if so where ? If not, where can I buy a license ?
I own a copy of Amiga4ever, but don't know if it has that SDK.

Thanks,
Regards

I highly recommend taking a look at this GCC cross compilation toolchain: https://github.com/bebbo/amiga-gcc

It comes with the NDK installed and various preinstalled headers for often used libraries.

3.1 has been obsolete for over 20 years, why not develop for a modern AmigaOS version? You can get the NDK here: https://os.amigaworld.de/index.php?lang=en&page=12

Hi,

I am developing a game. Yes the version I am targeting is old, but I really want to do it for these versions of the software, so that me and other retro fans can enjoy.

As to the libraries, can they be downloaded stand-alone? I already have my toolchain setup with Vbcc, just need the libraries.

Thanks,
Regards

The libraries are part of the OS, not of the NDK, so you should already have them.

Hi,
As for the libraries, and they being included on the OS, are you talking about the .library files in the Libs: Volume ? If so how do I refer to them in the compilation Host that I use for development ?
And where are the .h header files for me to be able to include them in my code ?

As for the subject, its supposed to be a platform, adventure game of a character. I am thinking of doing several episodes. This one, the first, is when he was a kid and went to elementary school. He must survive his classmates that are mean, and do his homework anyway.

Thanks
Regards

Yes, the header files are in the NDK.

Then you probably don't want to use the OS.
Just straight hit the hardware. You can do that in C as well.

I'm not sure about the legal situation of the AmigaOS NDK, and investigating that kind of stuff makes me very tired, so I prefer to stay on the safe side and release vbcc without it.

You should easily find the NDK on the net, legally or illegally, who knows. Or just buy the Amiga Developer CD V2.1.

The 3.9 NDK has never been sold, it has always been free. And it is not contained on the Developer CD anyway.

Read the initial post again and you may notice that he mentioned 3.1.

Even for OS3.1 programming the 3.9 NDK is better. Not only is it free but some of the bugs of older versions such as 3.1 are documented.

And it introduced some new bugs.

BTW, does anybody know if there is an official URL to download the free 3.9 NDK, which doesn't disappear soon?
amiga.com no longer works.

@phx:

There are aspects of 3.1 which are accurately documented in the 3.1 NDK but which are not accurately documented in the 3.9 NDK? That is not the case; the reverse is in fact true.

Does anybody know if they ever released or plan to release a NDK for 3.1.4 and/or the differences from 3.9? I know that, for example, Reaction was not owned or present at the time of 3.1.4’s release. And that there are likely new icon and workbench library functions in 3.1.4

For 3.1.4, use the 3.9 SDK, the API extensions made in 3.1.4 are those that came from 3.9.

Hey Thomas. Nice to see you again. So there were no new calls implemented in any of the libraries for 3.1.4 or nothing that isn’t private? Will there be for 3.2 and if so, will there be a new NDK?
