Yes.  I've finally pushed the fix for this.  Thanks!

I've just pushed a fix for this to the development version.  (Invoking
the image would get Scheme 48 try to automatically reload the POSIX
shared library, and that was buggy.)

Thanks for the report!

Build s48 1.8 on Freebsd5.5 Failed

s48.org:

I am trying to compile Scheme48 1.8 on FreeBSD 5.5 with --enable-gc="bibop", but I got following error when
I 'sudo gmake':

cc -c  -DHAVE_CONFIG_H -D__COMPILING_SCHEME48_ITSELF__
-DS48_HOST_ARCHITECTURE=\"i386-unknown-freebsd5.5\" -I ./c -I./c -I./c/bibop -g -O2 -pthread -o
c/unix/socket.o c/unix/socket.c
c/unix/socket.c: In function `s48_get_host_by_name':
c/unix/socket.c:362: error: syntax error before "t"
c/unix/socket.c:377: error: `t' undeclared (first use in this function)
c/unix/socket.c:377: error: (Each undeclared identifier is reported only once
c/unix/socket.c:377: error: for each function it appears in.)
c/unix/socket.c: In function `gethostbyaddr_thread':
c/unix/socket.c:452: warning: passing arg 1 of `gethostbyaddr' from incompatible pointer type
c/unix/socket.c: In function `s48_get_host_by_address':

c/unix/socket.c:476: error: `t' undeclared (first use in this function)
gmake: *** [c/unix/socket.o] Error 1

socket.c seems to be an interpace to POSIX socket. Now I dont know how to deal with the problem.

Thanks,

Re: Build s48 1.8 on Freebsd5.5 Failed

Hello Ray,

Please try  a patch:
----------cut here---------
--- c/unix/socket.c.orig    2008-08-06 12:37:30.800057262 +0400
+++ c/unix/socket.c    2008-08-06 12:37:37.484438183 +0400
 <at>  <at>  -19,6 +19,9  <at>  <at> 
 #include <string.h>
 #include <netinet/in.h>
 #include <arpa/inet.h>
+#ifdef HAVE_PTHREAD_H
+#include <pthread.h>
+#endif

 #include "c-mods.h"
 #include "scheme48.h"
----------cut here---------

Also, you should gmake, not make.

Best regards,
Vadim Zborovskii

The manual has an extra set of parentheses in the result.

SIGSEGV trying to bootstrap Scheme48 from VCS

	BTW, I'm getting segmentation faults while trying to bootstrap
	recent Scheme48 revisions from the Mercurial repository using
	some likewise recent Scheme48 versions.

	E. g., when trying to bootstrap Scheme48 rev. dc9216ef6864 using
	Scheme48 rev. dc9216ef6864, which was in turn built with
	Scheme48 1.8:

$ mkdir +build-1 
$ cd +build-1 
$ ../configure --prefix="$HOME" 
...
$ make \
      ../build/filenames.make \
      i-know-what-i-am-doing \
      c/scheme48.h \
      ../build/initial.image-{32,64}
...
cd ../ps-compiler &&					     \
	(echo ',batch';							     \
		echo ',config ,load ../scheme/platform-interfaces.scm';	     \
		echo ',config ,load ../scheme/rts-packages-64.scm';          \
		echo ',config ,load ../scheme/prescheme/interface.scm';	     \
		echo ',config ,load ../scheme/prescheme/package-defs.scm';   \
		echo ',exec ,load load-ps-compiler.scm';		     \
		echo ',exec ,load compile-twospace-gc-64.scm';		     \
		echo ',exit'						     \
	) | scheme48 -h 8000000 &&					     \
		mv ../scheme/vm/scheme48-twospace-heap-64.c ../c

AC_ARG_ENABLE() isn't used quite properly

	There's a problem with S48_GLIB and some other Autoconf macros
	used by Scheme48's configure.in currently.  Consider, e. g.:

$ nl -ba s48_glib.m4 
     1	### s48_glib.m4 --- S48_GLIB macro  -*- Autoconf -*-
     2	# serial 1
     3	dnl
     4	dnl
     5	dnl
     6	AC_DEFUN([S48_GLIB], [dnl
     7	AC_ARG_ENABLE([glib],
     8	[AC_HELP_STRING([--enable-glib],
     9	                [Use the glib event loop])],
    10		[dnl Check for glib-2.0
    11	  	 PKG_CHECK_MODULES(GLIB, glib-2.0, AC_DEFINE(HAVE_GLIB), AC_MSG_WARN(glib-2.0 not found))
...

	I. e., the PKG_CHECK_MODULES(GLIB, ...) (and the rest) will be
	executed whenever --enable-glib or --enable-glib=ARG is given,
	no matter what the ARG will be.  In particular, the GLIB checks
	will be made whenever --enable-glib=no is given, or the form
	treated synonymously to it by Autoconf: --disable-glib.

	(That way, I was really quite a GLIB user for some time.)

	The proper way to use AC_ARG_ENABLE() would be, e. g.:

AC_DEFUN([S48_GLIB], [dnl
AC_ARG_ENABLE([glib],
[AC_HELP_STRING([--enable-glib],
