This document describes how to install the libraries needed to get squash
running on an empeg.

----- DOWNLOAD -----

I choose to install the libraries by hand.  The libraries needed are:
libmad, tremor (libivorbisdec) and libFLAC (which also needs libogg).
You can get the libraries needed at these urls:

ftp://ftp.mars.org/pub/mpeg/libmad-0.15.0b.tar.gz
http://www.xiph.org/ogg/vorbis/download/tremor_cvs_snapshot.tgz
http://dl.sourceforge.net/sourceforge/flac/flac-1.1.0.tar.gz
http://www.xiph.org/ogg/vorbis/download/libogg-1.0.tar.gz

----- SETUP -----

If you are using the toolchain created with debian, you do not need to
create any shared libriaries (since it uses much newer glibc it seems
difficult to get it to run this way on the empeg).  So run these before
compiling:

export SQ_HOST=arm-linux
export SQ_PREFIX=/usr/local/i686-linux-gnu
export SQ_OPTIONS=--enable-static --disable-shared

Otherwise, if you are using the hijack toolchain, you can use shared
libraries.  Run these before compiling:

export SQ_HOST=arm-empeg-linux
export SQ_PREFIX=/usr/local/i686-arm-cross
export SQ_OPTIONS=--enable-static --enable-shared

----- CONFIGURE/COMPILE -----

For libmad use (and then make && make install):

./configure --build=i686-linux-gnu --host=$SQ_HOST --prefix=$SQ_PREFIX $SQ_OPTIONS

For tremor (libivorbisdec) use (and then make && make install):

./autogen.sh --build=i686-linux-gnu --host=$SQ_HOST --prefix=$SQ_PREFIX $SQ_OPTIONS

For libogg (needed for libFLAC), run these thre commands (and then make
&& make install):

./configure --build=i686-linux-gnu --host=$SQ_HOST --prefix=$SQ_PREFIX $SQ_OPTIONS
find -name Makefile -exec perl -i -pe's/CC = gcc/CC = `$SQ_HOST`-gcc/' "{}" \;
perl -i -pe's/CC="gcc"/CC="`$SQ_HOST`-gcc"/ libtool

For libFLAC, add "LDFLAGS=-L/usr/c++/lib " to the front of the command
if you are using the debian toolchain (and then make && make install):

./configure --build=i686-linux-gnu --host=$SQ_HOST --prefix=$SQ_PREFIX $SQ_OPTIONS

----- INSTALL ------

The libraries are now in $SQ_PREFIX's lib directory.  If you are using
the hijack toolchain you need to copy the shared libraries (*.so*) onto
the empeg.  I suggest using tar to tar the files, then ftp the tar file
to the empeg.  This ensures that you get the symlinks correct.

----- OTHER LIBRARIES -----

I have not tried to install libncurses or libfftw.  If you would like
to try this, you may reenable these features in the Makefile (it's
near the top by ifdef EMPEG).

If you do compile ncurses, you would have the empeg display, the control
fifo -and- the ncurses display all running at once!

If you compile the fftw library, you will have the spectrum analyzer
running on the ncurses interface only (as of now).  Also, the StrongARM
may not be able to handle the floating point calculations that the fftw
library will try to do.
