Still carry my old Cubic install from pre MorphOS-2.0 days around and as far as calling make and source-code coloring goes it just works (after assigning "devkits:" some random place).
Even looking up names works partly (everything in a inlcude file is o.k. stuff that points to an autodoc fails) but thst probraly just a minor configuration error.

->
- install Cubic including the old MorphOS-SDK found on the CD
- disable that old SDK by removing all thinks "devkits:" from user-startup
- install current SDK
- change settings for C++ dictionary

Or just use Scribble ;)
