# Run this script to download and cross-compile dependencies for win32.
#
# A directory named deps will be created and/or populated in the current
# directory.  Upon successful completion (be patient), the compiled
# dependencies will be packaged into an archive named deps.tar.bz2 in the
# current directory.  To install the dependencies, execute this command:
#
# tar xjf deps.tar.bz2 -C $PREFIX
# 
# where $PREFIX is the path to your mingw32 toolchain.  If problems occur,
# check stdout and stderr for clues.  You may be able to easily determine
# the problem and make the necessary corrections.  These packages will be
# downloaded and built:
#
# SDL 1.2.14
# boost 1.43.0 (headers only)
# libogg 1.2.0
# libpng 1.4.2
# libvorbis 1.3.1
# lua 5.1.4
# openal-soft 1.12.854
# zlib 1.2.5
#
# This script requires a working mingw32 toolchain and other basic tools.
#
# Example usage:
#   ./makedeps.sh -H i486-mingw32 -p /usr/i486-mingw32 -m "-j8"
#
# Bugs: Each time the script is run, all of the dependencies will be
# rebuilt, even the ones which were already built successfully.

Yoink Win32 Dependencies
Created `date +"%d %b %Y"`

These dependencies were generated automatically by makedeps.sh, a script
available in the Yoink repository.  You should find here all the header
files, DLL's, implibs, and pkgconfig files required to build Yoink that are
not provided with the standard mingw32 toolchain.  Yoink itself can be
built with mingw32 and these installed dependencies like this:

./configure --host=$HOST --prefix=$PREFIX \\
            PKG_CONFIG_PATH=$PREFIX/lib/pkgconfig
make installer

These files are licensed such that their general distribution under
reasonable conditions is allowable.  The copyrights of these binaries go to
their various respective owners.  Look up the specific library for specific
terms and conditions, or see the file COPYING in the Yoink package.
