[M3devel] trouble installing on a Debian lenny system.

Looking at your message, and trying to imagine the documentation 
changes, it suddenly doesn't seem so easy.  For one thing, I'm not 
familiar enough with the various systems to know what to say.

This crash isn't a matter of a documentation change.  If the stable 
release crashes during installation, it probably need to be replaced 
with one that doesn't crash.  Or is that just a problem on Ubuntu,
Debian and related distributions?

The http://modula3.elegosoft.com/cm3/ page says only:

:  If you would like to
:
:     * install on Ubuntu, Debian or a related distribution, or
:     * install a recent snapshot of CM3,

: you will want to read these more specific installation instructions.

: Alternatively, continue reading the general instructions below. 

Which, I suppose wasn't worded strongly enough to warn me off the "more 
general" method.

Perhaps it should say, 

: you will need to use these different installation instructions,.

: Otherwise, continue reading the general instructions below.


**********

On the page of "CM3 5.5.1 Installation on Ubuntu 7.10 and Similar 
GNU/Linux Distributions"

there's a list of software you should already have installed.  It should 
include cvs.

I gather that normally there isn't a bootstrapping problem from one 
compiler to the next.  The CVS instructions should mention that 
you have to start with a new cm3-min- file, and not proceed from the old 
compiler, or and old cm3-min-.  And, in fact, they do.  So this was my 
fault for not noticing it.

A friend of mine once said that his mother was a superhero, and that her 
superpower was the ability to follow instructions correctly.  I'm 
starting to realize how true that is.

***********

When it says,

: the newest available stable tarballs (version 5.4.0) are too old.

it should perhaps say that they do not work, as

: the newest available stable tarballs (version 5.4.0) are too old and 
: do not work.

By the way, what was too old about them -- are they no longer compatible 
with current versions of Ubuntu, Debian, or other related 
distributions?

	Do you mean that there was no reason to run the commands

              ./do-cm3-core.sh buildship

              ./install-cm3-compiler.sh upgrade

	?

And I have no idea how to document Realclean, or even how to use it.  
I've found the cm3 option

	cm3 -clean

.  Is realclean something like this, as

	cm3 -realclean

?  And if so, what is the difference?

I'd be happy to try.
