./config之后，出现如下问题：
checking for sdl-config… no
checking for SDL - version >= 1.2.0… no
* The sdl-config script installed by SDL could not be found
* If SDL was installed in PREFIX, make sure PREFIX/bin is in
* your path, or set the SDL_CONFIG environment variable to the
* full path to sdl-config.
configure: error: * SDL version 1.2.0 not found! 这是因为没安装libsdl1.2，安装后即可：
sudo apt-get install build-essential libsdl1.2-dev
