Daniel Gibson 2e47865234 Use updated minizip version for unzip

The implementation is now in framework/minizip/*
instead of framework/Unzip.cpp

This was version 0.15beta, now we use 1.1 from
zlib 1.2.7/contrib/minizip

Some code had to be adjusted for this, but it got
cleaner on the way

CHANGES

Compared to the original DOOM 3, the changes of dhewm 3 worth mentioning are:

64bit port
SDL for low level OS support, OpenGL and input handling
OpenAL for audio output, all OS specific audio backends are gone
OpenAL EFX for EAX reverb effects (read: EAX on all platforms)
A portable build system based on CMake
(Cross-)compilation with mingw-w64

GENERAL NOTES

Game data and patching

This source release does not contain any game data, the game data is still covered by the original EULA and must be obeyed as usual.

You must patch the game to the latest version.

Note that Doom 3 and Doom 3: Resurrection of Evil are available from the Steam store at

http://store.steampowered.com/app/9050/

http://store.steampowered.com/app/9070/

Compiling

The build system is based on CMake: http://cmake.org/

Required libraries are not part of the tree. These are:

zlib
libjpeg (minimum v6, v8 recommended)
libogg
libvorbis
libvorbisfile (may be part of libvorbis)
OpenAL (OpenAL Soft required, Creative's and Apple's versions are made of fail)
SDL v1.2
libcurl (optional, required for server downloads)

For UNIX like system these libraries need to be installed (including the developer files). It is recommended to use the software management tools of your OS (apt-get, portage, rpm, BSD ports, MacPorts, ...).

For Windows there are two options:

Use the provided binaries (recommended, see below)
Compile these libraries yourself

Create a distinct build folder outside of this source repository and issue the cmake command there, pointing it at the neo/ folder from this repository:

cmake /path/to/repository/neo

OSX users need to point cmake at OpenAL Soft (better solutions welcome):

cmake -DOPENAL_LIBRARY=/usr/local/lib/libopenal.dylib -DOPENAL_INCLUDE_DIR=/usr/local/include /path/to/repository/neo

Using the provided Windows binaries

Get a clone of the latest binaries here: https://github.com/dhewm/dhewm3-libs

There are two subfolder:

32bit binaries are located in "i686-w64-mingw32"
64bit binaries are located in "x86_64-w64-mingw32"

Issue the appropriate command from the build folder, for example:

cmake -G "Visual Studio 10" -DDHEWM3LIBS=/path/to/dhewm3-libs/i686-w64-mingw32 /path/to/repository/neo

cmake -G "MinGW Makefiles" -DDHEWM3LIBS=/path/to/dhewm3-libs/x86_64-w64-mingw32 /path/to/repository/neo

The binaries are compatible with mingw-w64 and all MSVC versions.

Cross compiling

For cross compiling a CMake Toolchain file is required.

For the mingw-w64 toolchain "i686-w64-mingw32" on Ubuntu precise it looks like:

set(CMAKE_SYSTEM_NAME Windows)
set(CMAKE_SYSTEM_PROCESSOR i686)

set(CMAKE_C_COMPILER i686-w64-mingw32-gcc)
set(CMAKE_CXX_COMPILER i686-w64-mingw32-g++)
set(CMAKE_RC_COMPILER i686-w64-mingw32-windres)

set(CMAKE_FIND_ROOT_PATH /usr/i686-w64-mingw32)

set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

Then point CMake at your Toolchain file: cmake -DCMAKE_TOOLCHAIN_FILE=/path/to/Toolchain.cmake -DDHEWM3LIBS=/path/to/dhewm3-libs/i686-w64-mingw32 /path/to/repository/neo

Back End Rendering of Stencil Shadows

The Doom 3 GPL source code release does not include functionality enabling rendering of stencil shadows via the depth fail method, a functionality commonly known as "Carmack's Reverse".
