+# configure.host -- JACK Audio Connection Kit version.
+#
+# This script and the system-dependent header directories it uses were
+# adapted for JACK from gcc/libstdc++-v3/configure.host.
+#
+# We've tried to keep it as close to the original as possible, while
+# removing a bunch of os-specific files that didn't seem relevant.
+# The primary goal has been to avoid changing the cpu-dependent
+# atomicity.h headers.
+#
+# If you need to make changes, the relevant GCC documentation may
+# prove helpful, <http://gcc.gnu.org/onlinedocs/porting>, especially
+# the <http://gcc.gnu.org/onlinedocs/porting/Thread-safety.html>
+# discussion of <atomicity.h>.
+#
+########################################################################
+
+# This shell script handles all host based configuration for libstdc++.
+# It sets various shell variables based on the the host and the
+# configuration options.  You can modify this shell script without needing
+# to rerun autoconf/aclocal/etc.  This file is "sourced" not executed.
+#
+# You should read docs/html/17_intro/porting.* to make sense of this file.
+#
+#
+# It uses the following shell variables as set by config.guess:
+#   host                The configuration host (full CPU-vendor-OS triplet)
+#   host_cpu            The configuration host CPU
+#   host_os             The configuration host OS
+#
+#
+# It sets the following shell variables:
+#
+#   cpu_include_dir        CPU-specific directory, defaults to cpu/generic
+#                          if cpu/host_cpu doesn't exist.  This is
+#                          used to set atomicity_include_dir.
+#
+#   os_include_dir         OS-specific directory, defaults to os/generic.
+#
+#   atomicity_include_dir  location of atomicity.h,
+#                          defaults to cpu_include_dir
+#
+# It possibly modifies the following variables:
+#
+#   OS_LDFLAGS             extra flags to pass when linking the library, of
+#                          the form '-Wl,blah'
+#                          (defaults to empty in acinclude.m4)
+#
+# If the defaults will not work for your platform, you need only change the
+# variables that won't work, i.e., you do not need to explicitly set a
+# working variable to its default.  Most hosts only need to change the two
+# *_include_dir variables.
+
+
+# DEFAULTS
+# Try to guess a default cpu_include_dir based on the name of the CPU.  We
+# cannot do this for os_include_dir; there are too many portable operating
+# systems out there.  :-)
+
+# HOST-SPECIFIC OVERRIDES
+# Set any CPU-dependent bits.
+# Here we override defaults and catch more general cases due to naming
+# conventions (e.g., chip_name* to catch all variants).

+
+Darwin/MacOSX port for Jack : architecture changes in the implementation
+========================================================================
+
+Build Dependencies
+==================
+
+Apple Developer Tools
+  gcc 2.95.x or 3.x, the standard OSX 10.3 gcc-3.3 compiler works fine
+  MacOSX10.3 SDK package
+
+GNU tools
+  autoconf >= 2.57
+  automake >= 1.6.3
+
+optional tools
+  libtool >= 1.5	(to build from CVS)
+  pkg-config >= 0.15.0  (to build from CVS)
+  doxygen		(to build documentation)
+  libsndfile >= 1.0.0	(for some example-clients)
+  GNU readline		(for some example-clients)
+
+All non-Apple tools are available from `fink' or `darwinports'.
+
+Since fink is not well-integrated with OS X, you must define a bunch
+of environment variables...
+
+  export ACLOCAL_FLAGS="-I /sw/share/aclocal"
+  export CFLAGS="-I/sw/include"
+  export CPPFLAGS=$CFLAGS
+  export LDFLAGS="-L/sw/lib"
+  export PKG_CONFIG_PATH="/sw/lib/pkgconfig:/usr/lib/pkgconfig:/usr/local/lib/pkgconfig:/opt/local/lib/pkgconfig"
+
+
+Shared memory
+=============
+
+The system V shared memory is not very reliable on Darwin/MacOSX, so
+POSIX shared memory API is the preferred default.  To override, use...
+
+  ./configure --disable-posix-shm
+
+
+Jack server audio cycle
+========================
+
+On Linux, the jack server audio cycle (jack_run_cycle function) is
+called in a real-time SCHED_FIFO thread.  On Darwin/MacOSX, the
+jack_run_cycle is directly called inside the CoreAudio audio callback.
+
+
+External client activation
+===========================
+
+Jack Linux implementation use system fifo/pipe to trigger the clients
+real-time callback from the server : the first client of an external
+subgraph is triggered, does it's job and wakes up the next one in the
+list, and so on until the last client that wakes up the Jack
+server. This avoid uneeded context switches between the server and
+clients and thus is more efficient.
+
+This Linux implementation works also on Darwin/MacOSX but is not very
+efficient : audio gliches occur quite frequently.
+
+A more efficient system for external client activation has been
+developed. It use low-level mach messages system to implement fast IPC
+between the Jack server and the running clients. The Darwin/MacOSX has
+a very efficient Remote Procedure Call (RPC) implementation that can
+be used: the Jack server activate each external client in turn in a
+loop.
+
+On the client side, each client uses an additionnal thread only used
+for the real-time process callback, that will be triggered by the Jack
+server using this fast RPC mechanism.
+
+
+Real-time threads
+==================
+
+The Darwin/MacOSX system use a special class of scheduling for
+real-time threads.
+
+Since the server audio cycle is called directly from the CoreAudio
+callback, there is nothing special to do on the server side. On the
+client side, the thread used to call the "process" callback from the
+server is made real-time, using the mach thread API.
+
+
+Compilation and installation
+=============================
+
+- In the jack/jack folder, you'll have to produce the version.h
+manually from the version.h.in file ): Edit the version.h.in, replace
+the JACK_PROTOCOL_VERSION value with the one found in configure.in and
+save as a new version.h file. You should get something like "#define
+jack_protocol_version 6" in the file.
+
+Several packages need to be installed before compiling Jack :
+
+- Fink dlcompat (fink.sourceforge.net) : this package define the
+dlopen, dlsym... API used in Jack to load drivers and internal
+clients. The package has to be installed before compiling Jack.
+
+- fakepoll is a implementation of the poll function using select. The
+Fink version of poll does not work correctly, thus the public domain
+"fakepoll" code has been used instead. It is directly included in the
+Jack Darwin/MacOSX port.
+
+- PortAudio (www.portaudio.com) : PortAudio is a free, cross platform,
+open-source, audio I/O library. The Jack CoreAudio driver actually is
+implemented using PortAudio. The PortAudio source code for MacOSX has
+to be installed and compiled to produce a framework called
+"PortAudio.framework" that will be used in the Jack link phase.
+
+
+Several targets are available in the Project Builder project :
+
+- jackd :  build the Jack server ("jackd" executable)
+- jack framework : build the "Jack.framework" library.
+- driver :  build the PortAudio driver as a "jack_portaudio.so" shared library.
+- jack_metro :  build the "jack_metro" executable.
+- jack_lsp :  build the "jack_lsp" executable.
+- jack_connect :  build the "jack_connect" executable.
+- jack_disconnect :  build the "jack_disconnect" executable.
+
+Server, driver and library installation :
+-----------------------------------------
+
+First copy the Jack.framework in /Library/Framework. Then as root : 
+
+  # cp jack_portaudio 	/usr/local/lib
+  # cp jackd 		/usr/local/bin
+
+Launching Jack server :
+-----------------------
+
+By default buffer size is 128 frames and sample rate is 44100.
+
+  $ jackd  -v -R -d coreaudio 
+
+To setup a 32 frames buffer and a 4800 Hz sample rate : 
+
+  $ jackd  -v -R -d coreaudio -p 32 -r 48000  
+
+Performances
+=============
+
+The Darwin/MacOSX implementation is quite efficient: on a G4/867 Mhz,
+the Jack server can run with a 32 frames buffer size without noticable
+problems.
+
+
+Known problems or unimplemented features
+=========================================
+
+- thread cancellation : the pthread API pthread_cancel is not
+completely available on Darwin/MacOSX. Thread cannot be cancelled in
+the general case: they must use explicit cancelation points like
+"pthread_testcancel" (see the "jack_client_thread" function)
+
+- xruns detection and report: not implemented.
+
+
+Possible improvements
+======================
+
+- The audio driver is built on top of PortAudio. It may be more
+efficient to directly use the CoreAudio API in order to avoid
+additional buffer copy and interleaving/disinterleaving operations.
+
+- The project uses Project Builder.  It would be helpful to work on
+the autoconf and automake tools as the Linux version.  In this case,
+the macosx/config.h file would have to be removed and generated by
+configure, and jack/version.h will be generated automatically from
+jack/version.h.in
+
+- Better separation of Linux and Darwin/MacOSX only code.
+
+The Jack port for Darwin/MacOSX version has be done by:
