2. Copy the Cubic CD to your hard disk. Copy the unpacked SDK 52.22 (no other version - file names in the SDK are important) to the "contributions/os4-sdk/" directory of the Cubic installation. Run Cubic's installation and select the C++ add-on for installation. Let it intstall the SDK - it's detected automatically and offered for installation. The add-on can install the SDK on non-OS4-systems, too, for cross-compilation. Do not run the installation contained in the SDK.
You mean version 51.22 ? And where do we find that ? Hyperion's site only has 53.x !
You will not find it on Hyperion or other official sites connected to AmigaOS unfortunately as far as I know. You have to ask people to share it with you I'm afraid.
That sucks. Trixie's work-around @ amigans.net and utilitybase.com require having the C/C++ Add-On package (from the Cube IDE distribution) installed , which is impossible unless you have Hyperion SDK 51.22.
