Still doesn't install here.

Says it has detected the OS3.9 CD and then it barfs.

This bug was reported over a year ago and still hasn't been fixed, doesn't exactly inspire confidence...

@Hans

For example a "100% system-legal" app could still have a NULL pointer error that could work on OS3.9 most of the time (and crash the whole system the rest of the time); OS 4.0 would catch this and bring up the grim reaper.

No version of the NDK advocates this (writing to $0, etc.).

@LiveForIt

Thanks for the reply.

>OS3.9 NDK might suggest things that is no longer safe

OS4.0 doesn't seem to be very compatible with OS3.9 software, eg. several of my programs which are AFAIK 100% system-legal apparently don't run properly under OS4.0. It doesn't seem right to lay the blame for this on OS3.9, it is rather a problem with OS4.0.

That poll is missing "Want to run OS4 but awaiting the existence of an AmigaOne emulator"

>If develop software you should defiantly upgrade, the development tools in OS4 SDK is way better then OS3.9 NDK.

Really? Could you be more specific?

Years ago there were promises of updated ROM Kernel Manuals. They haven't been updated since 2.04 (over 15 years ago), it is now 4.0, they are in dire need of updating.

They don't need to be released in hardcopy of course, softcopy versions would do.

In particular some detailed ReAction coverage would be welcome.

Yeah, keep in mind that OS4 hasn't actually been officially released yet, the current official AmigaOS version is OS3.9. So that needs to still be fully supported. Also keep in mind that total AmigaOne production ever is in the range of a few thousand, and with no AmigaOne emulator available, this means that the OS4 userbase is likewise restricted to a few thousand, which cannot possibly increase since the machines which can run it have all been discontinued.

Whereas over 8 million classic Amigas have been sold, and anyone with a modern IBM-PC is able to run UAE, which means a potential userbase of hundreds of millions.

Not a very difficult decision if you ask me.

OS3.5/3.9 is the usual target platform of software I write. I can't compile for PPC architectures as I use UAE or A1200/060. There's also source code so that others can compile/port for OS4.0/MorphOS/AROS/PowerUP/WarpUP/Amithlon/whatever ...It's difficult to support effectively 7 platforms.
