Once you download the SDK_addon you will have already gcc that is able to compile clib4 code.
And yes. just use -mcrt=clib4.
At moment however i suggest to clone and compile development branch on clib4 so you have all latest changes not yet released.
And of course you have to put clib4.library in LIBS:

Hi,
after ten years I reinstalled from scratch AmigaOS on X1000. Now I want to compile some code which using pthreads and ipc. Clib4 has it.

And I want to ask, what is easiest or most (system) friendly way to install latest clib4.

I found:
- SDK addon from walkero
- apt-os4 from afxgroup
- clib4 from walkero, afxgroup and elfpipe

Thank you all for your work! And please, can you advice me what package is most convenient to future upgrades ?

And, howto use clib4 correctly? With -mcrt=clib4? Is it enough, or something else should be done?

Many thanks!!

Most of the work has been done in spawnvpe function we use for git and Cmake. Instead of using fork() you run the command and use pipes to communicate. On git it was worst because they use stdin/stout to communicate too (along pipes)..
There are other fixes but not related to a specific amiga part. I've changed also path handling to manage amigaos path
Everything is wrapped in specific #ifdefs

well done

since git is a well known example of a linux command that should be very portable but still has many modern dependencies that must be hard to complete or configure out, and which you have managed to patch to build and run on OS4, it would be great if you have a chance to write up a case study about how you did it. Or even point an AI at your diffs to let it write all about it.

@afxgroup

Absolutely AWESOME! Thank you!!!

@afxgroup

Really amazing / good work.. this really changes a lot of things.

One things, people perhaps don’t get, is this work will reduce need for ugly workarounds in many ports.

Finally, a proper git client. Don't get me wrong, sgit was fine for simple things, but this version is one million times ahead.

Thank you so much Andreas for working on this and the clib4, which is a crucial tool.

I've just released a full Git client for AmigaOS4

We are tested it a lot and it seems to work very well. Keep in mind that you can't expect the same Linux/windows/mac speed because we have just one core that do everything.. So for example on X5000 git will be faster (even if there is a small problem on this machine). On the other machines you can't expect the same speed.
But for "normal" repositories it should work without any problem. If you think that git is stuck somewhere just wait.. be patient.
I will try to speed up it a little bit in next release.

Thank you!

I reinstalled my X1000 to clean AOS4.1FE-u3. New installation after ten years.

And finally tested Gabrielle and XTools. Thank you very much @jaokim!



It seems good!

@AmigaOldskooler

Count me among those who like the addition of headlines to the roundup. They make it easier to read and more professional-looking. I appreciate the time you put into researching and writing these every month.

One minor correction: It's "depscan" (one 'e'), not "deepscan".

Would it be possible to break the blog into multiple pages? (One per month, perhaps?) It's become so big, with so many large images, that it takes a long time to load, and I can no longer view it with Odyssey as it runs out of memory trying to load all the images.

Well I was able to order it by saying I led in another country. GOt the download, but having all kinds of trouble unpacking and then installing. I finally got it installed without any errors. But it crashes on me everytime I start the game. It will play the videos and has a DSI error and crashes out.

Anyone else hav a similar issue?

@Skateman

It's really great what you've achieved here as a small community. And yes, I too have been following developments around Mirari.

I have always been interested in audio/NVME driver development, and it seems that the MotphOs team has done a great job here. As I could see in your videos, MorphOs is already running splendidly on this board.

Of course, Mirari won't be able to replace my X5000, but it's remarkable how much support it's getting, and I think that will continue in the long term. There is currently zero driver development for the hardware on the X5000.

It will probably take ages until AmigaOS 4.1 boots for the first time, as there is simply a lack of support and developers. Personally, I consider this machine to be perfect MorphOS hardware, which you have really succeeded in creating.

@all
Thank you all for the kind words regarding our Mirari project. At the moment as most of you know there are boards with the ExecSG guys to work on the kernel. For now this has some delays due to (e5500 - X5000) multicore stuff they are working on. We will wait and see when there is progress to be mentioned. Besides that MorphOS developments are going strong. NVMe drivers have been optimized and Harald has created the onboard audio drivers with 192Khz recording functionality. Frank Mariak did the Qoriq onboard network driver next to all his hard work to optimize MorphOS 3.20 for running on the Mirari. I try to update the blog https://mirari.vitasys.nl/the-first-rebirth/ as much as possible.

Hi everyone,

The AmigaOS 4 Monthly Roundup covering January 2026 has just been published over on Old School Game Blog.

Hope you'll enjoy it! Cheers!

@DigitalDesigns
During Amiga40, I had the opportunity to play with the Mirari for a while. I own an x5000/20 and I have a comparison, and I think the x5000's advantage isn't obvious. What's more, I believe the Amiga will eventually get multicore support, and the Mirari will be able to show its full performance. Of course for a single core, the only things that matter are the MHz, RAM speed, etc. so x5000 wins. BTW, great job, and I'm in line for this machine.

@joerg

I already have X5000 which is best system for Amiga OS4.

@joergQuote:
The Mirari will not be faster than the X5000 for AOS4.
The project's goal was not to create the fastest machine.
Rather, it was important for the authors to create a relatively modern PPC motherboard with an open U-Boot that is compatible with various PPC operating systems.
This opens the door for MorphOS to the closed hardware ecosystem associated with Apple, on which it is mainly based.
The latest versions of Apple's G4 and G5 hardware were released 20 years ago.
The future of OS4 is unknown.

deleted double post, again

A 970 (G5) Mac is probably still much faster.
