"""Build Pygame dependencies using MinGW and MSYS

Configured for Pygame 1.9.2 and Python 2.5 and up.

By default the libraries are installed in the MSYS directory /usr/local unless
a diffrent directory is specified by the --prefix command line argument.

This program can be run from a Windows cmd.exe or MSYS terminal. The current
directory and its outer directory are searched for the library source
directories. Run the program from the pygame trunk directory. The Windows
file path cannot have spaces in it.

The recognized, and optional, environment variables are:
  PREFIX - Destination directory
  MSYS_ROOT_DIRECTORY - MSYS home directory (may omit 1.0 subdirectory)
  CPPFLAGS - preprocessor options, appended to options set by the program
  CFLAGS - compiler flags, appended to options set by the program
  LDFLAGS - linker options, prepended to flags set by the program

To get a list of command line options run

python build_deps.py --help

This program has been tested against the following libraries:

SDL 1.2.15
SDL_image 1.2(.10+) hg changset 45748e6e2f81
SDL_mixer 1.2.12 hg changeset b455bc681654
SDL_ttf 2.0.11 hg changeset d9a600fa3c4a
smpeg SVN revision 391 (built separately with MSVC++)
freetype 2.4.8
libogg 1.3.0
libvorbis 1.3.2
FLAC 1.2.1
mikmod 3.1.12 patched (included with SDL_mixer 1.2.12)
tiff 4.0b7
libpng 1.6.0b1
jpeg 8c
zlib 1.2.5
PortMidi revision 217 from SVN
untested with GCC 4.6.1: ffmpeg revision 24482 from SVN (swscale revision 31785)

The build environment used: 

GCC 4.6.1
MSYS 1.0.17
dx7 headers
yasm 1.2.0


The build has been performed on Windows XP, SP3.

Build issues:
  An intermitent problem was noted with SDL's configure involving locking of
  conftest.exe resulting in various C library functions being reported unavailable
  when in fact they are present. This does not appear to be a problem with the
  configure script itself but rather Msys. If it happens then just rerun
  msys_build_deps.py.

#   Build specific code
#

# This list includes the MSYS shell scripts to build each library. Each script
# runs in an environment where MINGW_ROOT_DIRECTORY is defined and the MinGW
# bin directory is in PATH. Four build control environment variables are
# defined: BDCONF, BDCOMP, BDINST and BDCLEAN. They are either '0' or '1'. They
# represent configure, compile, install and clean respectively. When '1' the
# corresponding action is performed. When '0' it is skipped. The installation
# directory is given by PREFIX. The script needs to prepend it to PATH. The
# script's HOME directory is the source code root directory. The msvcrt version
# is given as BDMSVCRT_VERSION. BDMSVCRT is where to place a shadow libraries
# which hide the normal MinGW C runtime export libraries. Various gcc flags are
# in CPPFLAGS, CFLAGS, and LDFLAGS. INCLUDE is undefined.
#
# None of these scripts end with an "exit". Exit, possibly, leads to Msys
# freezing on some versions of Windows (98).
# 
# The list order corresponds to build order. It is critical.
