There are three inline files still missing because of missing features of 'sfd2inlinecpp'. "cia.h" file uses explicit library base argument. "mathieeedoubbas.h" and "mathieeedoubtrans.h" pass double precision numbers in pairs of data registers.
Adding these missing features to 'sfd2inlinecpp' is planned.
GCC Pack 0.5 released today, contains an almost complete set of inline files for AmigaOS API calls working with both C and C++ compilers.
Inline files shipped with AmigaOS NDK do not work with C++, because this C++ compiler does not support specifying CPU registers for function arguments.
I wrote 'sfd2inlinecpp' tool, which generates proper inlines, the tool is included in the pack, so inlines for third party libraries may be generated.
What do I do on the software side now? I plan to release GCCPack 0.4 soon, (containing also C++ compiler), but to do this I have to regenerate all the system API inlines. The problem is C++ compiler doesn't support placing function arguments in fixed CPU registers. Older style approach, placing local variables in fixed registers, has to be used.
'fd2pragma' with SPECIAL 41 option almost does this, but well. Almost. It does not use 'static inline' for API calls. I write my own 'sfd2inline' then.
QoaPlay 0.8 released on Aminet. QoaPlay is a command-line player for Quite OK Audio files.
Changes in this version: fixed playback of stereo files in frequency halving mode.
I always wanted to have a stack based programming language on Amiga, where AmigaOS API functions are just operators of the language. With a fast compiler. Then I have created one. Bzted 0.1 is released.
IFFChunkTool won the contest. What a nice surprise.
I have finished a first working version of QOA player for Amiga – QoaPlay 0.6. In short: lossy compressed files (5:1 compression) play on 68030@25 MHz (44.1 kHz stereo). My humble 68020@28 manages 44.1 mono or 22.05 stereo, but with some improvements in the code it should be able to join the club.
I have submitted QoaPlay to Amiga 40 Tool Jam 2025, https://itch.io/jam/amiga-tools-jam-2025/entries. Binary can be downloaded there.

Git working trees are a time saver. At least for me.

My adventures with writing C++ programs for Amiga without the standard library. Overhead of empty apllication has been reduced below 0.5 kB.
