I was trying to use Merlin32, and ran into an annoyance. So my first
question--is there documentation on how to use Merlin32? I downloaded it
from https://github.com/apple2accumulator/merlin32, and I don't see any
documentation there (let me know if I missed it).
I used Merlin-16 on my Apple IIgs all the time, and it works fine to compile
the following short trivial program (the first example in the Merlin Pro
manual, which is available at archive.org):
*DEMO PROGRAM 1
org $300
BELL equ $fbdd
START jsr BELL
rts
I put that in a file demo.s, and ran:
merlin32 . demo.s
(I didn't "install" merlin32, just compiled it, since I don't need the
macros, and didn't want to fiddle with it much before trying it out).
But Merlin-32 barfs over this. It seems to think there are "Link Files"
which can have ORG and DS commands (and some other opcodes) in them, and
other files, which can have code, and EQU, and cannot have ORG (based on
IsLinkFile() in a65816Link.c).
I'm guessing the minimum useful Merlin32 project is two files, with
the Link File including the assembly code, but what exactly is the syntax
I need to use?
I want to eventually compile a semi-substantial amount of code, which will
need blank areas in it, something like:
org $300
[ some code, but not much ]
org $380
[ more code ]
where I want it to just put 0's to fill in space (if any). Can I do that with
Merlin32 in one source file?

I wouldn’t expect 0’s in the output just by changing an ORG. I would expect

to have to use DS to define space to end up with 0’s.

In article <56a6a515-512e-444a...@googlegroups.com>,
Thanks for the quick reply! This version works fine (for my simple starting
project), and was easier to compile.
I switched to duckduckgo.com a few years ago (when Google searches were
becoming likely to show me social media crap on technical subjects), and it's
odd that duckduckgo doesn't show the brutaldeluxe page in the top hits for
"merlin 32". It just shows the github version. Googling "merlin 32" does
show the brutaldeluxe site as the top hit. This is how I got confused--I
just followed the only apparent site. And it doesn't help that the github
site never directly references the brutaldeluxe site (at least not that I
can see). I didn't realize it was a 3rd party fork since I wasn't really
paying attention.

The updated Merlin 32 has a number of bug fixes and enhancements, but also has this bug, which renders it unusable for SourceGen. I could add an explicit link file like I do for ca65, but Merlin isn't supposed to work this way (IMHO).

The relevant bug is https://github.com/apple2accumulator/merlin32/issues/35

The ACME cross-assembler has an explicit "!align" directive.

DS \ applies at the END of the file, regardless of where it's placed.
However, you could do something like this:
org $300
...
ds $380-*

Ahh, you're right. That's only true of RELocatable files.

FWIW, Lane Roathe's fork (https://github.com/lroathe/merlin32) is more stable.
