Re: [cc65] 65tris (avoiding bit rot part 3)

Hi Groepaz,

The file PORTING contains in the section 'apple2' this statement:
'[PORT COMPILES, BUT IS COMPLETELY UNTESTED !!!]'

But I get this with a recent cc65 snapshot:
$ make apple2
apple2 ...
apple2/apple2.h(10): Error: Macro redefinition is not identical
65tris.h(240): Error: Macro redefinition is not identical

Generally I would have thought that the cc65 conio layer would allow
to create something like a tetris game without any target specific
code. But your tar file contains quite some assembler code and lots of
target specific stuff - and at least parts of them already come with
cc65 ?!?

Beside that the project seems to be in a - let's a say little
inconsistent - state. I.e. this section in makefile doesn't make much
sense to me:

CC65_INCLUDE=/usr/lib/cc65/include
export CC65_INC

Beside that I don't think that absolute paths in makefiles are such a
good idea...

So answering your original question: I'd like to see a tetris clone as
cc65 sample. But it should emphasis the cc65 benefit of being able to
write target independent code. If you provide that in a consistent
state I'm happy to test the apple2 target (and provide info on disk
image creation/emulator usage).

Just my two cents, Oliver
