still having problems compiling

[Igor Gueths]

Hi all. I followed Cheryl's suggestion about editing the Makefile and
uncommenting duplex = -halfduplex, but I still get the same error message.
However, the code has changed from 52 to 69. I don't think this has any
significance over what could be going wrong, but there is the posibility
of me being wrong on this. For reference, I get the message: Make:
Commands commense before first target. Stop! I am attaching the new
Makefile for reference. Thanks again!

#				Linux

#    Linux users please note: many Linux audio drivers are
#    half-duplex, even through your sound card may actually
#    have full-duplex hardware.
#
#    The following settings are for the most "vanilla" Linux
#    sound configuration.  This should work with the OSS/Free
#    sound drivers and audio hardware which emulates a Sound
#    Blaster Pro.  If you get long delays, try also adding
#    -DLINUX_DSP_SMALL_BUFFER.	If you have fancier hardware
#    and/or drivers it's wise to start out with simple settings
#    like those below and experiment with fancier modes (for
#    example, full duplex) only after you're sure the basic
#    functionality is working.	Please see the detailed description
#    of the available flags which follows these declarations.
#
CCFLAGS =  -DAUDIO_BLOCKING -DLINUX -DHALF_DUPLEX -DM_LITTLE_ENDIAN
CC = gcc -O3 # for GNU's gcc compiler
LFLAGS = -lncurses -lm
#
# If the above LFLAGS doesn't work, try the one below.
#LFLAGS = -lcurses -lm
#
#   The following is a detailed description of these and other flags
#   you may want to specify or not depending upon the details of your
#   Linux sound configuration.
#
#	-DAUDIO_BLOCKING
#	    You almost always want to specify this.  If it's
#	    not present, Speak Freely may read short blocks of
#	    audio from the input source and send compressed
#	    packets filled with mostly silence.  The option is
#	    provided since it's required with some workstation
#	    audio hardware to avoid buffering problems.  However,
#	    some Linux configurations will encounter long delays
#	    between audio input and transmission which cannot be
#	    fixed entirely by setting the LINUX_DSP_SMALL_BUFFER and
#	    associated flags described below.  On such systems, you
#	    may need to also to build without AUDIO_BLOCKING defined.
#	    Such is the state of sound drivers for Linux that you may
#	    have to experiment with various settings of these
#	    variables to find a combination which works acceptably for
#	    your audio hardware and drivers.
#
	-DHALF_DUPLEX
#	    Required if your audio hardware and/or driver does not
#	    permit simultaneous opening of the audio device for
#	    input and output by two separate programs.	As noted
#	    above, many Linux audio drivers are half duplex and
#	    require this flag even though the underlying audio hardware
#	    is full duplex.  Start by specifying this and then, if
#	    you believe your system capable of full duplex,
#	    experiment with turning it off.
#
	-DIN_AUDIO_DEV=\"/dev/audio\"
	-DOUT_AUDIO_DEV=\"/dev/audio1\"
#
#	    Some Linux audio drivers, for example the commercial
#	    OSS/Linux full-duplex driver, require full duplex programs
#	    to open separate /dev/audio and /dev/audio1 devices for
#	    input and output (or vice versa, presumably).  To
#	    configure the audio drivers in soundbyte.c to do this add
#	    the above to the CCFLAGS declaration.
#
#	    If your make or shell has different opinions about how to
#	    get quotes all the way from a make macro to the C compiler
#	    command line, you may have to experiment with the quoting
#	    on these declarations.  As a last resort, just edit the
#	    top of soundbyte.c and hammer in hard-coded definitions of
#	    symbols IN_AUDIO_DEV and OUT_AUDIO_DEV.  You can set the
#	    input and output audio device file names to anything you
#	    wish, not just the values given above.
#
#	-DLINUX
#	    Required for all Linux configurations.
#
#	-DLINUX_DSP_SMALL_BUFFER
#	    Some Linux sound drivers default to a very large buffer
#	    for audio input, which results in long delays between
#	    the time audio is received by the microphone and when
#	    Speak Freely receives it to be transmitted.  Defining this
#	    symbol attempts to set the audio input buffer size to
#	    2048 bytes to minimise this delay.
#
#	-DFRAGMENT_BUFSIZE=32
#	-DFRAGMENT_BUFPOWER=8
#    
#	    Control the audio input buffer size.  Only works if
#	    LINUX_DSP_SMALL_BUFFER is also defined. The buffer size is 
#	    calculated as FRAGMENT_BUFSIZE * 2 ^ FRAGMENT_BUFPOWER.
#	    Big input buffers will delay when transmitting (input ->
#	    recording) while too small input buffers cause clipping.
#	    If you have still trouble reducing the delay, try compiling
#	    _without_ -DAUDIO_BLOCKING.
#	    For more details please refer to README.Linux_OSS_bufsize
#	    and soundinit() of soundbyte.c.  This code was developed
#	    and contributed by Walter Haidinger (walter.haidinger at gmx.at)
#	    who reports that the above values work for him, with no
#	    clipping with just about one second delay.	These values
#	    are applicable only to the OSS sound driver; defining them
#	    requires -DLINUX_DSP_SMALL_BUFFER also be defined,
#	    otherwise they will have no effect.
#
#	-DLINUX_FPU_FIX
#	    Some older C libraries on Intel-based Linux systems did
#	    not place the processor's floating point unit into default
#	    IEEE exception handling mode, which could result in
#	    program crashes due to harmless floating point underflows
#	    to zero which occur in the LPC compression library.
#	    Defining this symbol compiles in code which explicitly
#	    sets IEEE exception handling.
#
#	-DM_LITTLE_ENDIAN
#	    This symbol should be defined when compiling on "little-
#	    endian" platforms such as the Intel x86 series and
#	    clones.  Little-endian machines store multi-byte values
#	    with the least significant byte first in memory; big-endian
#	    machines store bytes in the opposite order.  This should
#	    be defined unless you're running on a big-endian processor
#	    (a SPARC, for example). 
#
#	-DNEEDED_LINEAR
#	    Some Linux audio drivers (for example, the OSS/Free [but
#	    *not* the commercial OSS/Linux drivers for the very same
#	    card] drivers for the Ensoniq AudioPCI card) do not
#	    support 8 bit mu-law I/O (which has been the default
#	    /dev/audio format since the first Sun workstations were
#	    shipped with audio in the late 1980's).  Defining this
#	    symbol compiles in code, developed and contributed by
#	    Jean-Marc Orliaguet, which translates between the 16 bit
#	    PCM audio used by such drivers and the 8 bit mu-law
#	    representation expected by Speak Freely.  If you're able
#	    to send and receive audio but the sound is horribly
#	    distorted, you may need to enable this.  If you're able to
#	    play the mu-law sound files included with Speak Freely,
#	    for example:
#		    cat ring.au >/dev/audio
#	    without distortion, then it's unlikely this option will help.
#
#   Another problem frequently encountered by Linux users is the
#   permissions on the audio device.  To prevent eavesdropping, some
#   Linux distributions require root privilege to open audio input.
#   Unless you want to become root in order to run Speak Freely,
#   you'll need to change the permissions on /dev/audio (or whatever)
#   to allow regular users to open it for input.

# In order to build Speak Freely, you need to have the dmedia_dev
# packages installed.  In IRIX 5.3 and later, they are included with
# The IRIX Development Option (IDO), but may not be installed by a
# default installation of IDO. The command "versions dmedia_dev.sw"
# will tell you whether these components are present on your system.
# If they aren't, you need to install them before building Speak
# Freely.
#
# The following options are optimal for IRIX 6.5 with C 7.2.1.
# If you're compiling on an earlier version, adding the -float
# option may speed up certain compression modes.  If you get a
# warning about -float being ignored in non -cckr compiles, it
# has no effect on your system.

# (-fsingle is needed for pre-4.0 compilers and is ignored by 4.0 in
# ANSI mode.)  Defining THREADS enables multi-threaded operation in
# sflwld (and has no effect on any other component of Speak Freely).
# THREADS has been tested on Solaris 2.5 through 2.7 (a.k.a. 7) SPARC
# and requires POSIX thread support.  If you cannot build with THREADS
# defined, simply remove it from the CCFLAGS line below.  If you
# disable THREADS, you can also remove the "-lpthread" library
# specification from the LFLAGS line, which may cause an error if the
# system does not include the POSIX threads library.

#    the definition DUPLEX = -DHALF_DUPLEX later in this file.
