About this year … 2016
Again a year passed so I will try to give a short summary about things going on in the Freepascal world for Amiga-style systems.
In Januar 2016 a big change in Freepascal was done to fix the Varargs version of the amiga library version. All „array of const“ are replaced with the better „array of PtrUInt“ which is much better to emulate the open end parameter list
The MorphOS LCL implementation took a big step in the begin of the year until got the usual suspects to work. All resulted in the first MorphOS FPC release including LCL units in March 2016.
A little funny new experience started also in March. I created the first 64Bit ABIv1 AROS distribution. Mainly, of course because I need a test field for the FreePascal AROS x64. For me x64 would be the perfect successor of the i386-aros ABIv1. My suggestion for AROS developer would be to leave i386 ABIv0 as it is, backport changes to there. And change then to x64 ABIv1 (and do not use/promote i386 ABIv1). But the x64 AROS still need much work, many things still crash, much code still cast Pointers to integer so not 64bit ready. This is also the main reason the 64bit distribution did not get much new version, not much changed with the problems there, I retest the usual problems from time to time. Also the FPC 64bit had big problems, which I found out end of 2016 are mainly alignment problems, where AROS made it’s own life much harder than it should be. (reminder „stacked int“s)
EdiSyn got a new Version with some bugfixes and basic printing support. End of year it got also a ARM version of EdiSyn to public with some more advanced features.
I also tried EdiSyn on MorphOS and Amiga. But both have some problems because of the different behavior of MUI and Zune. And I did not took much work on it because on MorphOS there is already a very good Editor with syntax highlighting and on Amiga m68k it’s just too slow. But in principle it works just LCL need some more work.
LCL on a native Amiga got some improvements to work also if no Graphic card is present, like my A1200 and also ported the usual suspects to m68k Amiga.
I used already a Lazarus on Linux to cross compile to AROS i386, in April I created a Lazarus which can cross compile for all supported Platforms (AmigaOS 3, AROS, MorphOS). Because it worked to nicely I planed to release a Lazarus for Linux including the binutils and cross compilers for all Amiga systems. But I noticed it is very difficult, even to write a Manual how to install such a systems. Therefore I decided to create a virtual machine which includes Lazarus, cross compilers and binutils for all Amiga Systems. After Amiga OS 4 was added to Freepascal and LCL I released a 2nd Version including the Amiga OS 4 binutils and cross compiler.
ChainQ implemented FreePascal for OS4 long time before already but because of changes in FreePascal and without a maintainer it did not compile anymore. In April ChainQ resurrected it and fixed some basic things, make it self compiling again. Then I took the lead and implemented some OS4units bring FP-IDE to work and finally the LCL with the usual suspects for OS4. Which resulted to a Amiga OS 4 FPC release including LCL. I will continue to maintain the OS4 fpc but will not improve it much more, maybe someone will appear to continue it especially with the unusual interfaces can be found on AmigaOS4.
I continued to work on applications using my LCL. This time I got the idea to create a Map application showing routes of my bike GPS. I played around with google maps API and openstreet API. Openstreetmap is much better because google maps you are forced to use the google libs which is difficult at AROS. It get some releases for all available platforms. I also experimented with GPS support, first via a extra program later also directly inside Mapparium, which is still not released.
Long Time before I got the direct linking of C static objects to freepascal programs at AROS to work, which was really nice, but no real program resulted from it. On magoriums work on mikmod, I got an idea for a Delitracker like program for AROS, to Play my old modules. I results into my first native Zune program (so without LCL wrapper) ZuPaPlayer. And because Delitracker is working directly on MorphOS and Amiga I concentrated on AROS.
There I also noticed its rather difficult to write MUI applications in Freepascal. In C there are many many macros to make it easier, but they are not directly possible to convert to pascal. There is a muihelper unit in MorphOS with some starts to make it easier. I moved it to ami-extra to make it available to all platforms and extended it a lot. To test and prove the usability of it I started to port the example codes of the official MUI 3.8 release. On Amiga it works very nice on AROS it shows very good the differences of MUI and Zune.
Because ChainQ included support for 68000 processor which need some more alignment care. Because of this I created a little RTL for Workbench 1.3 which is really difficult because much things are not available.
This year also the port of FPC to ARM AROS including LCL and the usual suspects was done.
I try to bring the MUI-LCL to the official repository, started with the basic LCL implementation. Announced at mailing list. We will see how it goes.

Thanks for your work. I could focus on the deep technical things, because of your work on the upper level, and testing things, and your build servers, and supporting users in forums, and whatnot. Keep it up. Lets hope we can build more cool stuff with FPC together.
Thanks for your words, and thanks for your work, especially the fight for our platforms inside FPC core developer team 😉 and of course the syscalls which make it so much easier. Keep it up. We will create more cool stuff.
