我尝试在我的 Mac OSX Lion 上为 PyPy 安装 Pygame 版本 1.9.1release。我先跑pypy config.py了pypy setup.py install。我将配置添加到安装过程中，因为我看到它正在尝试使用普通 python 进行配置（正确安装，但会导致导入错误）。在安装过程中，有很多警告，例如：

src/overlay.c:44:5: warning: implicit declaration of function 'PyObject_Free' is invalid in C99 [-Wimplicit-function-declaration]
PyObject_Free ((PyObject*)self);
^

但它也为我提供了 2 个类似的错误：

    In file included from src/scale_mmx.c:33:

对我来说，PyPy 卡在生成似乎是 C 中的块注释的行对我来说似乎很愚蠢。为什么它将注释封装在 asm 和 volatile 中是我无法理解的。但这是提供给我并在常规 python 中工作的代码。那么这是一个错误吗？还是我错过了什么？

Chances are PyPy has some #defines different than CPython (for good or bad reasons) and pygame chooses to use something else (based on a badly thought out #else with implicit assumptions) that tries to compile invalid C. I'm just guessing though, you would need to follow why and how the same code is/is not compiled on CPython.
