How to import shared code from banks with ca65?
by yaros on 2018-12-13 (#230392)

I have my boot.asm

Code:

.segment "CODE"
.include "boot_shared.inc"
.segment "VECTORS"
    .word nmi
    .word reset
    .word irq
.segment "BANK0"
.scope b2
    .include "boot_shared.inc"
    .segment "VECTORS0"
        .word nmi
        .word reset
        .word irq
.endscope

And boot_shared.inc

Code:

.import main

reset:
    ...
    lda #0
    jsr lib_SwitchBank
    jmp main

nmi:
    ...
    rti

irq:
    rti

.export lib_SwitchBank
.proc lib_SwitchBank
    and #$0F
    sta $8000
    rts
.endproc

I want somehow to import lib_SwitchBank into any bank, but instead I get "Duplicate external identifier: `lib_SwitchBank'" even though (and I might be wrong) they are on the same address... Scope doesn't seem to have. I should not have too many of those routines, but I need at least a couple. How can I correctly link it?

Dunno, but try removing ".export lib_SwitchBank" from boot_shared.inc and moving it to boot.asm at top-level scope.

Duh... Sorry, should have thought about that... Thank you!

Instead of including the same code multiple times in your source, shouldn't it be possible to do this with the linker config? Just define a segment that's included multiple times in the ROM image.

I don't think the ld65 configuration language allows a single SEGMENT to be copied into multiple MEMORY areas.
