Re: opcodes port instructions in cgen.info yield "unbound variable: opc-file-path "

[Alan Lehotsky <qsmgmt@earthlink.net>]

I see what my problem was.  I was expecting too much from running  
interactively.

The suggestion regarding running various generators (like the `(cgen- 
asm.in)' is going to always fail complaining
about the unbound variable.  You would need to invoke guile and cgen  
with all the appropriate flags that are hidden in
the make files.  The porting suggestion is directed to the idea that  
you run interactively, looking at the generated .c and .h files
as they flash by on the screen.  Once you're happy, then you go off  
and do the

         make stamp-TARGET

or whatever in the subdirs.  I will see if I can write up a patch to  
the docs regarding this.
