Is possible use old SDK in AmigaOS4.1 with some tool make software for old machines? and of course same time new SDK make OS4.1 native stuff?
and i mean system friendly things. or new OS version mess things ways even 68k emulation dont help. i mean some things are recent osses done differently like Reaction GUI. only thing why i think this my Classic Amiga is loud. thing what i think is install HiSoft C++ enviorment... i dont even know if works or not but works at least OS3.9 very fine.

@Vanhapolle

The OS4 SDK can only make OS4 PPC software.

But you can use the NDK 3.9 and VBCC for example to make 68K software.

I mean this but actually i mean i can even test these 68k things ? exepct of course things which need trackdisk.device,audio.device. btw before i get AOS4.1 i maybe try code one idea for classic amiga. which tells if i unerstanded things correctly.

@Vanhapolle

At first I thought you meant supporting OS4.0 on old machines.

The OS4 SDK is set up for OS4 native apps only. I have a "dual" set up with the OS4 SDK and SAS/C for 68K.

The SDK is a free download but I'm not aware of a free 68K SDK or NDK as it was called on OS3.9 in a combo package with compiler. There is the OS3.5 ADCD V2.1 but that is a paid product.

The ADCD has StormC but the IDE used to crash on OS4. IIRC it used GCC as the compiler or one version did, that might have been V4.

You can get an NDK here. You just need a compiler. As stated VBCC should do the trick.

@Hypex

ishave developer cd,and i have hisoft c++ i in theory have all tools but i dont know if i can test 68k code with amigaos4.1 final edition or there is reason why is not bet possible solution if is not. maybe UAE in AOS4.1 final edition if i can transfer data for it to AmigaOS4.1 side,and i can have virtual graphicscard on it...

Yes, but not all development tools works under AmigaOS4.1
AsmOne does not for example, vbcc works.

this will be tricky, some header files have the same name for OS4 SDK and OS3 NDK,
you will need to write a few scripts that reassign the paths and before you run "make all", so the compiler don't find the wrong header file.

I have no idea if HiSoft C++ works under AmigaOS4.1, you just need to try.

you can simply use a hex editor change the name from trackdisk.device to cw.device, diskimage.device or a1floppy.device, this should work.

You can setup classic AmigaOS3.x inside E-UAE, with all your classic development tools, even the tools AmigaOS4.1 don't like, like AsmOne / AMOS etc.

Yes can run 68k software in AmigaOS4.1, if you wont to check if your software is system friendly.

Quote:

Generally speaking if your going to write system friendly code it wont be problem, but if your going to run the program in a debug there might be problems, for example you can't enable debugger in BlitzBasic2, its not supported.

Quote:

Yes nothing stops you from doing that, now with JIT enabled UAE, its going to be fast to compile code under EUAE.

Quote:

You don't need to transfer anything, directories on AmigaOS4.1 side can be virtualized as partitions on EUAE/AmigaOS3.x side.

I use a stripped down version of the GeekGadgets compiler for 68k (gcc 2.95). It needs OS4 ixemul.library version 51.10 with the "cc1" command disabled (no petunia) in SYS:Prefs/Compatbility prefs. Fewer code changes are required to get programs compiling for OS4.x and 68k than with other compilers like SASC.

Interesting, I never got that to work, though I did have 51.9 not 51.10, is there a download link for 51.10 anywhere?

I didn't have cc1 blacklisted either hmmm...

The ixemul.library 51.10 is an OS4 library but it works with my 68k GG compiler. I just stumbled on it by accident at:
http://strohmayer.org/sfs/files/ixemul_51.10_bin.tar.bz2

Originally, I just turned Petunia off altogether to get my GG 68k compiler working. However, I eventually isolated the crashes in cc1 and just blacklisted that program. There are numerous 68k versions of ixemul.library available on Aminet and at: http://sourceforge.net/projects/amiga/files/ixemul.library

I've never gotten the newer versions at Sourceforge to work with OS4 but one of the older versions did (I don't remember which one).

EDIT: You could run into some "path" confusion with the OS4 SDK, which is why I run a setup script in one shell window to keep the "path" assignments local to the one shell I'm using to compile for 68k.

48 , probably 48.0 is the best alternative for ixemul.lib that should still remain coss platform compatible. after that os4, morphos and finally amiga went all their own way. if you need later linux features it might make sense to use versions from amiga.sf to compile for amiga-m68k. paricularly the latest version:
http://amiga.sourceforge.net/?showpackage=ixemul.library

@wawa
The only thing I use ixemul.library for is compiling with my GG compiler. I think the 48.0 version worked on my µA1 but the only one that works on my SAM & X1000 is the OS4 native verison 51.10. I'm sticking with what works.

As reported in PM, have now got it working on my X1000, 'vforked' processes enter infinite loops on exit on my SAM.

Now to see if I can get something more complex than hello world to compile!

How this last hing what you talk is done. Meaned something like that i dont always have correct words.
