Thanks, you may save some people some time 

Now, here goes the newbie questions, please bear with me: I
am new to 
Smalltalk and have looked at the manual page at 
http://www.gnu.org/software/smalltalk/gst-manual/gst.ht
ml and I can't 
make the examples work. I've run the test suite and all
test pass but 
when I try to run Blox as stated in 3.7.1 (gst -qK
blox/Run.st) these 
files don't exist, I think it's equivalent to run

gst -qK browser/Run.st

but the I get this:

$ gst -qK browser/Run.st
"Scavenging... 89% reclaimed, done"
"Scavenging... 89% reclaimed, done"
"Scavenging... 87% reclaimed, done"
"Scavenging... 89% reclaimed, done"
"Scavenging... 88% reclaimed, done"

I have a directory named blox-tk and I'm sure I'm missing
something but 
how can I correct this? How does Smalltalk look for
packages, how does 
it know 'Browser' corresponds to browser-tk? The manual
does not explain 
this or I haven't found it.

Another problem is I seem unable to type examples at the
st> prompt. If 
I type

x := Array new: 20 !

I get

stdin:1: assignment to undeclared variable x

but I thought you don't have to declare anything in
Smalltalk!?

Thanks for your help and sorry for the long message but I'm
totally new 
to this.

Thanks
Lucia

I think not many people are running 2.95.x at this time.

Yes, that should be fixed.  The online manual has not been
updated for a 
long time.  You can do "make pdf" after
installing and get nice manuals 
in pdf format (or also "make html").

The browser is cross platform, it works equally for Tk and
Gtk (but the 
latter is experimental).  But you probably don't have the
Tcl/Tk 
development packages installed.  Look for tclConfig.sh in
your disk, it 
is probably not there.

No, you do have to declare temporary variables.

| x |
x := Array new: 20!

Note also that, after you end the "interaction"
with the exclamation 
mark, the "x" variable ceases to exist.

This is not true with the graphical browser, which has
temporary 
variable like these, but also permanent, workspace-visible
variables.

No problem, if there are any suggestions you can make I (and
the few 
other contributors) are all ears.

I had no problem doing both after I updated my (aging)
system. The 
manuals are more up to date and I have started to play
around with the 
browser. It's very interesting.

I loaded the development files for Tcl/Tk but I had to load
also glib 
2.0, I had glib 1.2 and configure complained about it but
you have to 
look carefully while it runs to notice that. Maybe I'd
suggest you 
repeat the problems at the end for the users who don't
stare at 
configure running?

Okay, I thought I had some "interactive"
environment there but the 
browser does it.

Maybe if you group the problems configure encounters at the
end it would 
make things easier, or maybe something like "configure
found problems. 
Look at config.log" would suffice.

Thanks!

glib is only necessary for Gtk, not Tk.

Thanks for the hint.  I'll add something like: "the
following modules 
will be built/will not be built".
