+Installing hosted Inferno from source
+
+Overview
+
+     Like the native kernels  emu relies on  several  auxil-
+iary libraries (the source of which it often shares with the
+native kernels).  Emu itself is built by the  mkfile in the
+emu subdirectory containing the platform-specific source for
+the host platform.  Each library has its own    mkfile;  the
+various  components  are  made  in  the  right order by the
+mkfile at the root of the Inferno tree.   The    mkfile  for
+each  platform  will also invoke  mk recursively to make the
+appropriate libraries for a given configuration.
+
+     The Unix emu variant generally is  covered  by  `POSIX'
+(with  common  extensions)  but  each Unix port has one file
+that   differs   considerably   for   each   port,    namely
+emu/platform/os.c, the differences corresponding to the dif-
+ferent ways  under  Unix  of  implementing  kernel-scheduled
+threads efficiently.
+
+     There  are  working  emu  versions   for   FreeBSD/386,
+Irix/mips,  Linux/386, NetBSD/386, MacOSX/386, MacOSX/power,
+Plan 9, Solaris/sparc, and Windows (NT,  2000  and  Explorer
+plug-in).   Each platform typically uses mechanisms specific
+to the host operating system to implement Inferno's internal
+thread/process  structure.   POSIX  threads  have often been
+found to be insufficient (poorly implemented) on some  plat-
+forms, and if so are avoided.  See  kproc in  emu/*/os.c.
+
+     Source is included for ports to HP/UX  (S800  architec-
+ture),  Solaris/386, and Unixware, in case someone wishes to
+take them up now, but we have not determined their fitness.
+
+     The Plan 9 hosted implementation is unusual in that  it
+supports several processor types:  386,  mips,  power (Power
+PC) and  sparc.  Furthermore, all versions of   emu  can  be
+built on any processor type, in the usual way for Plan 9.
+
+     Otherwise, as distributed,  emu for a platform can only
+be built when running on that platform.
+
+     One unusual variant makes the whole of Inferno a  plug-
+in  for Microsoft's Internet Explorer, giving the same envi-
+ronment for Inferno applications running in an HTML page  as
+is  provided by hosted or native Inferno.  That is, there is
+not a distinct `applet' environment with special programming
+interfaces.   The  source for the various plug-in components
+is found in  /tools/plugin and    /usr/internet  within  the
+Inferno  tree;  they  use the version of  emu defined by the
+configuration file  /emu/Nt/ie.
+
+Build steps
+
+     All the libraries and executables can  be  built  in  a
+tree containing only the source code.  To do that for a sup-
+ported variant of hosted Inferno, on Unix or Plan 9, do  the
+following in the root of the Inferno tree:
+
+1    Edit    mkconfig  to  reflect  your  host  environment,
+     specifically  ROOT  (which  must  be  an  absolute path
+     name), SYSHOST and OBJTYPE.  The comments in  the  file
+     should help you choose.
+
+2    Run  makemk.sh to rebuild the   mk  command,  which  is
+     used to build everything else.
+
+3    Set  PATH (or  path on Plan 9)  to  include  the    bin
+     directory for the platform, which will now contain the
+     mk binary just built.  On Unix, export  PATH.
+
+4    Then  mk nuke to remove any extraneous object files.
+
+5    Finally,    mk  install  to  create  and  install   the
+     libraries,    limbo  compiler,  emu for hosted Inferno,
+     and auxiliary commands.  The rules do that in an  order
+     that ensures that the commands or libraries needed by a
+     later stage are built and installed first.  (Note  that
+     a  plain   mk will not suffice, because it does not put
+     the results in the search path.)
+
+Doing something similar  on  Windows  or  Plan  9  currently
+requires  the  executable  for    mk  to be available in the
+search path, since there is no  equivalent  of    makemk.sh.
+Otherwise  the procedure is the same.  On Plan 9, of course,
+the host system's normal version of  mk should be adequate.

+Bugs to support@vitanuova.com, though.
+
+March 2006: initial MacOSX 10.4/x86 port
+
+12-Dec-2003
+Emu can use wm with Apple's X11R6 again.

+Inferno Services (6660, 6666-6676, 2202)
+
+26-Aug-2003
+In order to run and use Inferno services appropriately on OSX, you need to ensure that the Sharing System Preferences include an entry in the Firewall section that is turned on and looks like the following line:
+
+Inferno services (6660, 6666-6674)
+
+
+05-Jul-2003
+In order to support 1.4, the build will now use the default 'mk' provided with the Inferno distribution.  You can also copy tcshrc to the Inferno ROOT and source the file from that directory before running or building emu.  Modified mkfiles and sources are now available in the srcMacOSX archive.  You may also want to change 'mkconfig' with the following diff

+The build now uses the open sourced 'mk' from http://www.pdos.lcs.mit.edu/~rsc/software/
+
+There is a file .tcshrc at the root of this tree (..) that can be used to set up the environment required to build emu.
+
+
+
+28-Feb-2001
+
+The initial port has been provided by Corpus Callosum Corporation.
+
+This port of Inferno for Darwin, Mac OS X, and Mac OS X Server hosted environments currently provides base 'emu' support.  Wm, audio, and other services are not currently ported.  It has only been tested on UFS partitions and will require further testing for HFS+ support.
+
+Emu -c1 currently errors out as "Illegal instruction"
+
+Various malloc/free (from libc/System on Mac OS X/Darwin) warnings should be removed in the following version.
+
+eia devices will recognize /dev/ttyd.irda and /dev/ttyd.modem though both are completely untested (need to get updates to the RCX interface to test irda).
+
+The following modification was added to various 'mkfile' to support required redefinition of varios core functions.
+
+	<$ROOT/mkfiles/mkalloc-$SYSHOST-$OBJTYPE
+
+Some of the base libraries and utils will have *.pbproj files which were used to bootstrap the initial build system on Mac OS X (Public Beta).
+
+
+
+"Mac OS X" and "Mac OS X Server" are trade marks of Apple Computer, Inc.
