2. Aetherspace

Aetherspace是一个GNU退役的项目，不再进行维护也不会再有产出。

GNU Aetherspace 的核心是一个游戏引擎，叫做PySoy。这个游戏引擎使用C、GObject、cross-platfrom SIMD assembly和OpenGL着色器写的。

游戏引擎的前端是用纯C写的Python库，这个库金依赖于Python3和该引擎的后端。

游戏引擎的后端构建在Gnome库（GLib、GDK和Cairo等）之上的。引擎的后端并不依赖于Python，因此基于Gnome的应用程序可以使用后端提供的接口。

接着进行源码编译这个项目（但这并没有成功）

首先，需要安装Mercurial（相当于git）来获取源码，安装valac来编译Genie语言写的一些代码。这两个程序可以使用sudo apt-get install mercurial valac来安装。

接下来，获取libsoy和pysoy的源码：

hg clone http://hg.pysoy.org/libsoyhg clone http://hg.pysoy.org/pysoy

接着，分别编译libsoy和pysoy。（但是我的环境有问题？？？有些错误，没有解决。如果你能帮我解决这个问题请回复或者emai我：[e-mail]）

编译libsoy：进入libsoy目录执行以下三条指令。

./waf configure./waf buildsudo ./waf install

在build的过程中出现错误，看输出应该是和Genie语言有关的：

编译pysoy：进入pysoy目录执行以下三条指令。（PySoy依赖于python 3.1+和libsoy所以前提是libsoy编译安装成功，由于一般Linux发行版默认python版本为2，所以要加一些特殊辅助参数。）

PKG_CONFIG_PATH="/usr/local/lib/pkgconfig" python3 waf configurepython3 waf buildsudo python3 waf install

等上面的错误解决了才能进行下一步。
