[Amforth-devel] makefile correction?

[Elliott C. <ec...@te...>]

I am now looking at using avra under linux. Avra doesn't compile for me, 
so I am trying the static version. As recommended, I have downloaded 
amforth by svn, ... Accordingly, it appears that the makefile lines

DIR_ATMEL=../../Atmel

and

AVRA=avra -I $(DIR_ATMEL)/Appnotes2

need to be changed. I think  the first should end "core", and the other 
should end "devices"; and thus that the early MCU line should read 
MCU=devices/<device name>/device.inc.

Good guesses?

Can you post your compilation problems?

You should set DIR_ATMEL to the directory containing files
from AvrStudio (with the Appnotes directory). 

My installation of AvrStudio has "Appnotes", not "Appnotes2".

The original Windows directory is in my case 

c:\Program Files\Atmel\AVR Tools\AvrAssembler2

it contains avrasm2.exe and the Appnotes directory.
(I have it mounted on my FreeBSD but you might just as well
copy the "Appnotes" directory to your Linux partition)

Absolutly. They contain a few files from the Atmel Studio (I copied
them 1:1 from a windows box). The location may be different for others

Mine is as follows:
--------------
mt@ayla:~/avr/forth/amforth$ ls
appl  Atmel  core  doc  lib  misc  test  tools
mt@ayla:~/avr/forth/amforth$ ls Atmel
Appnotes  Appnotes2  avrasm2.exe  docs  Help  Partdescriptionfiles  STK500
mt@ayla:~/avr/forth/amforth$
--------------

other people may place the Atmel files at /usr/share/Atmel or so.

not really. The final command line is composed from
many variables in the Makefile. among them is

AMFORTH=../../core
INCLUDE=-I $(AMFORTH) -I $(AMFORTH)/devices/$(MCU)

the result is that 3 different include directories
are used: one with the Atmel files, one with the
core/ words and finally the core/device specific
things. The fourth include directory is . (current
working directory) which may contain a directory
words/ that is searched first for include files.
That way you can "overwrite" existing words
with your own ones. A feature I use alot for
testing new implementations/variants.

It's difficult, yes. But it works for me and I did
not found a better solution (yet).
