Unfortunately, that part doesn't work yet.  Here's what's missing.

Yes.  This was pointed out to me shortly after I sent out the
notices and I quickly fixed it, hoping that I was quick enough
to avoid too many downloads of the bad version.

two compile bugs found

Howdy

I'm cross compiling scheme48 0.56 for the Agenda VR3 PDA--runs Linux-vr. I
ran into a couple of problems getting it to compile.

1) using CONFIG_SITE=../agenda-config.site ./configure for some reason
some rather important CFLAGS and LDFLAGS weren't being picked up. 

CFLAGS needs "-s -mips2 -O2 -fno-exceptions"
LDFLAGS needs "-s -mips2"

It WAS picking up, however, -msoft-float for both these variables. I don't
know why it would use some of the CFLAGS line in my config.site but not
others...

2) During make lines 255 and 256 of c/scheme48.h redefine the symbols from
lines 222 and 223. Manually remove these and things compile fine.

socklen_t and MacOS X 10.0.3/Darwin PPC 1.3.3

Hi,

building scheme48 0.56 on MacOS X 10.0.3 works fine except for
c/unix/socket.c since MacOS X does not seem to know
socklen_t. 

./configure reports that it could not find socklen_t. doc/news.txt
states that socklen_t will be defined automatically then. Somehow this
doesn't seem to work on OS X. I attached the config.log and
config.status generated, I hope this is the information you need.

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

I can't reproduce that: my configure is silent about socklen_t.

Obviously, the wrong version of c/sysdep.h.in made it into the
distribution. Remove c/sysdep.h.in and run autoheader to regenerate
it. Afterwards run ./configure to generate the proper c/sysdep.h.

Sorry, I was not precise enough, configure said: "checking for
socklen_t... no"

I had to run autoconf in addition. Now it works fine, thank you!

Ciao,

Does Scheme 48 Dream of Electric Sheep?

Just logging a bug ...

This code in scheme/prim.scm ...

; The largest number of seconds that can be converted into a fixnum number
; of milliseconds.

(define maximum-seconds (quotient (- greatest-fixnum-value 1000) 1000))

... effectively means that a Scheme 48 process runs into trouble after
it has run for about six days.  This just happened to our spanking new
multithreaded ftp server.
