Porting to Playstation2.

Hi vm-dev,

As suggested on the squeak-dev mailing list, I should ask questions about
porting on this list. As this list is still new, I hope there are people
listening. :)

My first problem. Getting to the ports source on subversion. I downloaded
tortoise SVN and tried to do a SVN checkout on the location
http://squeak.hpl.hp.com/svn/squeak/trunk

At two locations I got the response REPORT request failed on
'/svn/squeak/!svn/vcc/default' REPORT of '/svn/squeak/!svn/vcc/default':
400 Bad Request (http://squeak.hpl.hp.com)

Anyone suggest anything I might be doing wrong? Either both my ISPs don't
have very badly configured smart proxies or I'm doing something wrong. I
suspect the later. If it is my ISPs, anyone have a snapshort archive I can
use?

I'm attempting to checkout to the location c:\squeak\src which I think is
where VMMaker wants it?

Thanks for any help,
David.

Well, I am at least. :)

Just did such a checkout and it worked fine. I have no proxies etc, your
issue is most probably this:

http://minnow.cc.gatech.edu/squeak/5596

Sure, I can fix one for you if all else fails. Mail me privately in that
case.

VMMaker tool can be told where the src tree is.

Re: Porting to Playstation2.

Hi Goran,

Great to see atleast two people on the list. It seems both my ISPs are
catching all HTTP requests. I noticed that one way around this was to use
SSL via HTTPS, but it doesn't seem the server is configured for this.
Another way was via port 81 but that doesn't seem to be activated either?
Can anyeone confirm both of these?

If you can supply a snapshot that would be great. Its really just so I can
get some examples of how to go about a port.

Thanks,
David.

Re: Porting to Playstation2.

You could use a webcrawler to download the source. Assuming you are on
a unix-like system, try

wget -r -np http://squeak.hpl.hp.com/svn/squeak/trunk/

(for me, reconfiguring my router's proxy allowed the checkout to work
just fine)

Re: Porting to Playstation2.

First, thanks Bert, the webcrawler solution worked like a charm. :) Now the
fun starts.

The first really basic question about VMMaker. Should the path to generated
sources overlap with the platforms code? Currently I have it pointing to
another location, but don't understand what gets copied from the platform
tree. There seems to be some hidden magic I'm not seeing.

I've setup a new directory with the following structure:

c:\squeak\src\platforms\ps2

\misc\ToCopy
Makefile
Makefile.pref
\plugins
-- nothing here yet --
\vm
sq.h
sqConfig.h
sqNamedPrims.c
sqPlatformSpecific.c
sqPlatformSpecific.h
sqPs2Exports.c
sqPs2Main.c
sqVirtualMachine.c
sqVirtualMachine.h

My makefile and its preferences get copied correctly, but the vm files
don't. Should the makefile simply refer back to the source tree, or is
another technique used? Once I get this sorted out I will commit the file
to my CVS so people can see my progress.

So far, with the above files all manually copied to the output directory,
and all the required functions stubbed out, I can compile an executable.

Thanks,
David.

The build process always has three directories:

./src/*
./platforms/*

and
./bld.

My usual sequence for making a unix VM is to do (in my newly created
build directory)

> ../platforms/unix/config/configure ; make

Anyway, my own VM question is wheather anyone has bothered to document
the unix display plugins?

I know that Ian's refactoring changed alot of stuff for the better but
he never documented how one goes about designing and writing one...

I ask because I wanted to try out different display libraries such as SDL..
