So I look at this.
1.
This software is written in FreePascal.
2.
./gavrasm -h
+------------------------------------------------------------+
| gavrasm gerd's AVR assembler Version 3.3 (C)2012 by DG4FAC |
+------------------------------------------------------------+
Calls: gavrasm [-ABEJLMQSWX] source[.asm]
gavrasm [-?DHT]
List of options:
-L Listfile off -M List macros
-Q Quiet, no screen output -S Symbol list in listfile
-B Beginners error comment -A Toggle ANSI output on command line
-E Longer error comments -D List all supported directives
-W Enable wrapping -T List all supported AVR types
-X Internal def.inc off -J Switch jump PC+X+1 to PC+X
-H -? List options (shows this)
gavrasm lacks the -I switch to specify a search path for files.
3.
So I cooked together a directory
mkdir tmp.gavrasm
cd tmp.gavrasm
cp ~/Forth/atmega/55_avra_4.6/. . # this is a working amforth setup from
appl/template
cp -a ~/Forth/amforth/releases/4.6/core/. .
cp -a devices/atmega32/. .
./gavrasm main.asm
gavrasm also lacks an option to specify the target controller directly.
I'm not sure that it guessed the correct (any?) target device.
This produces lengthy output, the interesting snippets being in main.err:

so, this is as far as I got in 20 Minutes ...
