Should anyone intervene?
What do you we need if AmigaOS support is dropped?
Or is this the 68k target?

People are dying.
Entire ecosystems are collapsing.
We are in the beginning of a mass extinction.
And all you can talk about is money and fairytales of eternal economic growth.
How dare you!

I think the only thing we need to do is to make a port of the latest 4.4 version and share with them the changes. You see, we didn't do anything like that for more than 12 years, so it seems logical to drop AmigaOS support.

Sounds like a good idea. That way they see signs of life for AmigaOS.

Thanks for spreading the word of our Amiga-News article from this morning. Together we can change things.
We have updated our article:

Soooo, not to let this die too quickly...has anyone looked at porting it yet?

I'd do it myself, but then i remember i can't, so...

So, we just need to wait for someone to step up. Until then, the older versions won't go anywhere. And if there is a need for newer tools, there is always a way to cross-compile.

I would try to do it but I am occupied with the WebKit port.

Ok, maybe with a joint effort then?

I downloaded the 4.4 sources, let configure run (smoothly) and am facing my first problem here

This patch should fix your problem:

The bigger issue is that pipe, (v)fork and some other functions are missing. Still looking into that.

Okay, and the next issue is that make assumes that Amiga compilers define _AMIGA instead of __AMIGA (not the two underscores).

Use this configure command to activate the Amiga parts in code (executed in abc-shell):


> CFLAGS="-D_AMIGA -D__USE_INLINE__" ./configure

This fails later, though:


gcc -DHAVE_CONFIG_H   -Isrc -I./src -Ilib -I./lib -DLIBDIR=\"/usr/local/lib\" -DLOCALEDIR=\"/usr/local/share/locale\"     -D_AMIGA -D__USE_INLINE__ -MT src/function.o -MD -MP -MF $depbase.Tpo -c -o src/function.o src/function.c &&\

Well, a bit. Do not expect wonders, though.

Right now I hit the limits of my knowledge. Make is doing something strange with replacing functions with defines. GCC really does not like this. Has anybody any idea how I have to update these to make them working?


#if defined(VMS) || defined(_AMIGA) || defined(__MSDOS__)

#define check_io_state()  (IO_STDIN_OK|IO_STDOUT_OK|IO_STDERR_OK)

#define fd_inherit(_i)    (0)

#define fd_noinherit(_i)  (0)

#define fd_set_append(_i) (void)(0)

#define os_anontmp()      (-1)

#else

It defenitly does not like the first set of brackets (the one of the function).

Cool, you're at least much better at this than me

No idea from me there, sorry

Would it help to include the original maintainer?
Maybe he likes to help out too?

@all
Keep in mind that the Amiga exclusive code in make has been there since the v3 and v4 might need much more changes in other parts as well.

Also, our current newlib is better than what it was 12-15 years ago, as a matter of completeness. So, things that were excluded back then now might be needed.

I am trying to point out that it might be needed to see the port like the previous Amiga code was not even there. Like a brand new port.

@walkero:

I guess the first decision is if we want to keep support for AmigaOS < 4.0 (= classic AmigaOS).

Trying to keep AmigaOS 3.x compatible, I do not see a lot of needed changes to the code.

But if you want to scrap support for older OS versions, we might want to rewrite major parts to be closer to the other OSes. But in this case I am not in a position to help as I lack inside in major parts of AmigaOS 4.x inner workings.

AFAIK Amigaos 3.x is already using make 4.x and gcc 12.1, latest gdb 13.x etc.

I guess you are talking about Bartman's excellent Visual Studio plugin. Yes, it contains make, gcc and gdb, but they are not native versions, but run on Linux, Mac, or Windows.

We are talking about a native make version; one you can run on your Classic or NG Amiga.

This my current state: https://github.com/josefwegner/make/tree/amigaos

It needs hacking the Makefile to compile and link amiga.c.

I will work on this issue later. Maybe we can get it to work without running configure. This would also allow me to build it with SAS/C.

Although it compiles, it does not do much yet. Most likely we need to rewrite the Amiga specific parts in src/amiga.c to use the new AmigaOS 4.x methods.

The latest version was ported and adapted to OS4 by ssolie, but did not release the sources on os4depot nor aniwhere else, only the binary
Perhaps it could worth updating to the latest version starting from his previous work?

That would be great. This is the only thing that it does at the moment:

Awesome so far

...any preliminary binaries to test?
