Statically link FFmpeg on Windows. This requires building a slimmed-down version of FFmpeg from source. The build process is documented in the README. Also add ffmpeg dependency to the nix flake.

xsystem4
|
|
========
|
|
|
|
xsystem4 is an implementation of AliceSoft's System 4 game engine for unix-like
|
|
operating systems.
|
|
|
|
Compatiblity
|
|
------------
|
|
|
|
See the [game compatibility table](game_compatibility.md) for a list of games
|
|
that can be played on xsystem4.
|
|
|
|
Building
|
|
--------
|
|
|
|
First install the dependencies (corresponding Debian package in parentheses):
|
|
|
|
* chibi-scheme [optional, for debugger]
|
|
* bison (bison)
|
|
* cglm (libcglm-dev) [optional, fetched by meson if not available]
|
|
* flex (flex)
|
|
* freetype (libfreetype-dev)
|
|
* glew (libglew-dev)
|
|
* meson (meson)
|
|
* libffi (libffi-dev)
|
|
* libpng (libpng-dev)
|
|
* libsndfile (libsndfile-dev)
|
|
* libturbojpeg (libturbojpeg0-dev)
|
|
* libwebp (libwebp-dev)
|
|
* SDL2 (libsdl2-dev)
|
|
* zlib (zlib1g-dev)
|
|
|
|
Then fetch the git submodules,
|
|
|
|
git submodule init
|
|
git submodule update
|
|
|
|
(Alternatively, pass `--recurse-submodules` when cloning this repository)
|
|
|
|
Then build the xsystem4 executable with meson,
|
|
|
|
mkdir build
|
|
meson build
|
|
ninja -C build
|
|
|
|
Finally install it to your system (optional),
|
|
|
|
ninja -C build install
|
|
|
|
### Windows
|
|
|
|
xsystem4 can be built on Windows using MSYS2.
|
|
|
|
First install MSYS2, and then open the MINGW64 shell and run the following command,
|
|
|
|
pacman -S flex bison \
|
|
mingw-w64-x86_64-gcc \
|
|
mingw-w64-x86_64-meson \
|
|
mingw-w64-x86_64-pkg-config \
|
|
mingw-w64-x86_64-SDL2 \
|
|
mingw-w64-x86_64-freetype \
|
|
mingw-w64-x86_64-libjpeg-turbo \
|
|
mingw-w64-x86_64-libwebp \
|
|
mingw-w64-x86_64-libsndfile \
|
|
mingw-w64-x86_64-glew
|
|
|
|
To build with FFmpeg support, you must compile FFmpeg as a static library:
|
|
|
|
git clone https://github.com/FFmpeg/FFmpeg.git
|
|
cd FFmpeg
|
|
git checkout n6.0
|
|
./configure --disable-everything \
|
|
--enable-decoder=mpegvideo \
|
|
--enable-decoder=mpeg1video \
|
|
--enable-decoder=mpeg2video \
|
|
--enable-decoder=mp2 \
|
|
--enable-parser=mpegaudio \
|
|
--enable-parser=mpegvideo \
|
|
--enable-demuxer=mpegps \
|
|
--enable-demuxer=mpegts \
|
|
--enable-demuxer=mpegtsraw \
|
|
--enable-demuxer=mpegvideo \
|
|
--enable-decoder=vc1 \
|
|
--enable-decoder=wmapro \
|
|
--enable-parser=vc1 \
|
|
--enable-hwaccel=vc1_d3d11va \
|
|
--enable-hwaccel=vc1_d3d11va2 \
|
|
--enable-hwaccel=vc1_dxva2 \
|
|
--enable-demuxer=asf \
|
|
--enable-protocol=file \
|
|
--enable-filter=scale \
|
|
--enable-static \
|
|
--disable-shared \
|
|
--extra-libs=-static \
|
|
--extra-cflags=--static
|
|
make
|
|
make install
|
|
cd ..
|
|
export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH"
|
|
|
|
Then build the xsystem4 executable with meson,
|
|
|
|
mkdir build
|
|
meson build
|
|
ninja -C build
|
|
|
|
To create a portable executable, it is neccessary to copy some DLLs into the same directory as xsystem4.exe.
|
|
You can determine the required DLLs with the following command,
|
|
|
|
ldd build/src/xsystem4.exe | grep mingw64
|
|
|
|
The `fonts` and `shaders` directories must also be shipped together with xsystem4.exe.
|
|
|
|
Installing
|
|
----------
|
|
|
|
If building from source, run:
|
|
|
|
ninja -C build install
|
|
|
|
to install xsystem4 on your system.
|
|
|
|
### Windows
|
|
|
|
The recommended way to install on Windows is to copy the xsystem4 directory
|
|
into the game directory. E.g. if Sengoku Rance is installed at
|
|
`C:\Games\AliceSoft\Sengoku Rance`, then your filesystem should look something
|
|
like this:
|
|
|
|
C:\
|
|
Games\
|
|
AliceSoft\
|
|
Sengoku Rance\
|
|
System40.ini
|
|
xsystem4\
|
|
xsystem4.exe
|
|
...
|
|
...
|
|
|
|
Running
|
|
-------
|
|
|
|
You can run a game by passing the path to its game directory to the xsystem4
|
|
executable,
|
|
|
|
build/src/xsystem4 /path/to/game_directory
|
|
|
|
Alternatively, run xsystem4 from within the game directory,
|
|
|
|
cd /path/to/game_directory
|
|
xsystem4
|
|
|
|
### Windows
|
|
|
|
If you've installed xsystem4 into the game directory as described above, simply
|
|
double-click `xsystem4.exe` to run the game.
