Instructions for Building EDuke32's Library Dependencies Targeting Win32 and Win64
==================================================================================

First, follow these instructions: http://wiki.eduke32.com/wiki/Building_EDuke32_on_Windows

Download the latest sources from the link provided.

The build output listed as "Desired Results" is what EDuke32 needs to function.

The desired results for each library in some cases may need to be installed to the compiler. "x depends on the results of y to compile" means that the build output of x must be added to the compiler in this way. Copy files listed in each category to the appropriate destinations. Unless otherwise noted, do NOT copy the ".dll.a" file or else the final product may depend on external DLLs (which you may actually want).

For MinGW (MinGW32):
from the compiler root (ex. C:/MinGW/)
  * headers: include/
  * libraries: lib/

For MinGW-w64:
from the compiler root (ex. C:/MinGW-w64/mingw32-dw2/)
  * headers: <target>-w64-mingw32/include/
  * libraries: <target>-w64-mingw32/lib/

Binaries (if mentioned) need to be present with the finished EDuke32 executables. They are not needed during compilation.

NB: Text formatted as code blocks are commands to be pasted into the Windows command prompt.

libogg
------
### Download ###
Download: libogg-<version>.tar.xz
  * Stable: https://www.xiph.org/downloads/
  * Git: https://git.xiph.org/ogg.git
### Build ###
    sh ./configure && make
### Desired Results ###
  * headers: ogg/config_types.h ogg/ogg.h ogg/os_types.h
  * libraries: libogg.a

libvorbis
---------
### Prerequisites ###
libvorbis depends on the results of libogg to compile.
### Download ###
Download: libvorbis-<version>.tar.xz
  * Stable: https://www.xiph.org/downloads/
  * Git: https://git.xiph.org/vorbis.git
### Build ###
    sh ./configure && make
### Desired Results ###
  * headers: vorbis/codec.h vorbis/vorbisfile.h
  * libraries: libvorbis.a libvorbisfile.a

libFLAC
-------
### Prerequisites ###
libFLAC depends on the results of libogg to compile.
### Download ###
Download: flac-<version>.tar.xz
However, Git HEAD is highly recommended.
  * Stable: https://www.xiph.org/downloads/
  * Git: git://git.xiph.org/flac.git
### Build ###
    make -f Makefile.lite libFLAC
### Desired Results ###
  * headers: FLAC/all.h FLAC/assert.h FLAC/callback.h FLAC/export.h FLAC/format.h FLAC/metadata.h FLAC/ordinals.h FLAC/stream_decoder.h FLAC/stream_encoder.h
  * libraries: libFLAC.a


zlib
----
### Download ###
Download: zlib-<version>.tar.xz
  * Stable: http://zlib.net/
  * Git: git://github.com/madler/zlib.git
### Modifications ###
  * Modify win32/Makefile.gcc as follows:
      * CFLAGS: change -O3 to -O2 for stability and possibly performance benefits.
### Build ###
    make -f win32/Makefile.gcc
    ar rcs libz_mini.a crc32.o deflate.o adler32.o zutil.o trees.o
### Desired Results ###
  * headers: (none)
  * libraries: libz_mini.a

libpng
------
### Prerequisites ###
Copy *.h from zlib to your compiler's include directory.
### Download ###
Download libpng-<version>.tar.xz
  * Stable: http://www.libpng.org/pub/png/libpng.html
  * Git: git://git.code.sf.net/p/libpng/code
### Modifications ###
  * Modify scripts/Makefile.gcc as follows:
      * Ensure ZLIBINC and ZLIBLIB point to the directory of zlib from above, or, rename your zlib directory so that, relative to the libpng directory, it is "../zlib". You will get a compile-time error if this is omitted or done incorrectly.
  * Copy the file "minipng.dfa" to the root of the libpng data.
### Build ###
    make -f scripts/pnglibconf.mak DFA_XTRA=./minipng.dfa CPP="gcc -E"
    make -f scripts/makefile.gcc libpng.a
    ren libpng.a libpng_mini.a
### Desired Results ###
  * headers: png.h pngconf.h pnglibconf.h
  * libraries: libpng_mini.a


libvpx
------
### Prerequisites ###
Download the binary of yasm (http://yasm.tortall.net/) for your host system architecture. Both builds target both architectures.
The build environment needs pr.exe (https://mingw-lib.googlecode.com/files/coreutils-5.97-MSYS-1.0.11-snapshot.tar.bz2).
### Download ###
  * Instructions: http://www.webmproject.org/code/
  * Stable: http://downloads.webmproject.org/releases/webm/
  * Git: https://chromium.googlesource.com/webm/libvpx
### Build ###
    sh ./configure --disable-vp8-encoder --disable-vp9-encoder --disable-multithread --disable-spatial-resampling --as=yasm && make libvpx.a
### Desired Results ###
  * headers: vpx/vp8.h vpx/vp8dx.h vpx/vpx_codec.h vpx/vpx_decoder.h vpx/vpx_frame_buffer.h vpx/vpx_image.h vpx/vpx_integer.h
  * libraries: libvpx.a


SDL
---
### Download ###
Download SDL2-devel-<version>-mingw.tar.gz
  * Stable: http://www.libsdl.org/download-2.0.php
  * Mercurial: http://hg.libsdl.org/SDL
### Build ###
    sh ./configure --disable-libc && make
### Desired Results ###
  * headers: SDL_*.h
  * libraries: libSDL2.a libSDL2main.a


dsound, dxguid, and dxguid_sdl
------------------------------
### Download ###
See Windows/src/dxlibs.
### Build ###
    make
### Desired Results ###
  * headers: ddraw.h dinput.h dsound.h (pre-positioned in Windows/include/dx)
  * libraries: libdsound.a libdxguid.a libdxguid_sdl.a
