[Flashforth-devel] assemble FlashForth for Arduino Uno

[Bruce C. <bc...@cf...>]

I have been trying for hours to assemble FlashForth for the Arduino 
Uno.  Soon I would like to compile to have it use the serial port (for 
an RS-232 console) but as my starting point I am trying to assemble the 
downloaded ff-atmega.asm file to generate the downloaded hex file.  It 
seems like this should be both trivial and documented by one or two 
paragraphs on the download page that contains the source and hex.

I have downloaded the AVR Studio for Windows, the Atmel 8-Bit AVR 
toolchain for Linux, avra for Linux and one or two other assemblers.  So 
far the best I have been able to do is about 40-50 errors and warnings 
when using avra.  If I recall correctly the error count was well over a 
thousand with Atmel AVR Studio.  The downloaded Atmel toolchain also had 
a lot of reported errors.

What assembler works?  What assembler did the FlashForth developer(s) use?

It looks like the code may have been assembled in a C environment since 
there is a comment in it that is commented out by a double slash.  Some 
of my reported errors are also due to "strlen" in the source which again 
suggests a "C" environment to me.  High in the downloaded listing file 
is  "AVRASM ver. 2.1.30 avr/src/ff-atmega.asm Wed Mar 22 22:08:36 2017" 
but AVRASM isn't in the toolchain I downloaded from Atmel.

Linux is by far my preferred OS but I can use Windows if necessary.

I'm just trying to get started.  Thank you for your help.
