AmiQute Qt6 Tutorial

Thanks a lot! I am getting closer to get it linked.

I hope this works ;)))

What am I doing wrong here ? It seems to try to link in some Linux stuff (I have installed the clib4 icu). Thanks!

For compiling I use George's Docker (which has clib4 Support).

EDIT: I think the warnings give the issue - these files in fact are missing, what I have is

root@2ea4d3de6572:/usr/src/RetroArch_exp# ls /opt/ppc-amigaos/ppc-amigaos/SDK/clib4/lib/libicui*

/opt/ppc-amigaos/ppc-amigaos/SDK/clib4/lib/libicuio.so.74.1

But for example the libicudata.so.74 is not there (and no idea where to get it from). Also while I have libstdc++.so I do not have libstdc++.so.6 which it is looking for.

icu for Qt6

@TheMagicSN

Just to try and keep up with your pace - what you want to do with the Qt sources is probably to create a .pro file for them (in case this doesn't exist alread!). This is very easy, look here :

Qmake tutorial

Run

> qmake-amige

On the .pro file to get the Makefile and configuration items.

Then, if you really want to link this part together with the rest of the objects, you can either copy-paste whatever command lines you need from the Makefile OR you can create some super-level project generator or Makefile that handles the conglomeration facilitation of the project. If your issue is, that you are building it on the Amiga (what a feat, damn...), then I can congratulate you : The build ituls work on the Amiga, just not right now. There will be news on this item at some point, I assure you.
