cc65 linker error compiling memory lib.

[Harry Potter]

Hi!  I am working on a cc65 memory library for the Atari 8-bit computers and am running into the following error message from the linker:

ld65: Error: atarixl_memx.cfg(26): Attribute expected, got 'OPTIONAL'

I attached the config file.  What could cause this?

atarixl_memx.cfg

memory area definitions don't use optional. If you don't want it output to the generated file then use "" for the file.

 

    PRNBUF_:    file = "",               start = $03C0, size = $0028;

Thank you.

I have another problem: how do I define the __RESERVED_MEMORY__ macro on the ld65 command-line?  I mean, how do I know what to assign to it?

[Harry Potter]

Never mind, I found the problem: the start address was set to $2000.  I set it to $2400, and it worked.

I know you solved your problem, but this is an examlpe of one I use

 

cl65 -t atari -Oi -T -Wl "-D__RESERVED_MEMORY__=0x3000" --static-locals -l temp.lst -o temp.xex temp.c

How do I know what to assign to __RESERVED_MEMORY__?

It seems to depend on what you're doing as I believe cc65 uses the upper regions of memory, so if

you want to change graphics modes, the call to _graphics can potentially overwrite some code/data

and obviously crash your program.

 

For example, I have a program that uses a standard _graphics(0) call, but I also need space for a _graphics(3)

so I reserved 1K for the extra screen mode as after creating, I switch back and forth without calling the graphics modes
