python - 在运行 Snow Leopard 的 Mac 上构建 PortAudio 和 PyAudio(架构问题)

Question

我想告诉您我的尝试，然后我非常欢迎您就如何正确设置 PortAudio 和 PyAudio 提供任何意见!

我尝试从 their website 安装稳定版和 svn 版的 PortAudio适用于运行 Snow Leopard 的 Core 2 Duo MacBook Pro。稳定版有一个 sizeof 错误 can be fixed(?) ，但是每天的 svn 版本可以通过 ./configure && make && make install 安装得很好(所以这就是我正在使用的)。测试已正确编译，我可以获得二进制文件以生成输出/可以读取麦克风输入。

好的，那么 PyAudio 就有麻烦了。从 source 安装我收到有关找不到库的错误消息:

我可以从 their .dmg installer 安装 PyAudio ，但它针对 python2.5。如果我将/Library/Python/2.5/site-packages/的所有相关内容复制到/Library/Python/2.6/site-packages/(这包括 PyAudio-0.2.3-py2.5.egg-info, _portaudio .so, pyaudio.py, pyaudio.pyc, and pyaudio.pyo)然后我的python2.6就可以识别了。

In [1]: import pyaudio
Please build and install the PortAudio Python bindings first.
------------------------------------------------------------
Traceback (most recent call last):
  File "<ipython console>", line 1, in <module>
  File "/Library/Python/2.6/site-packages/pyaudio.py", line 103, in <module>
    sys.exit(-1)
SystemExit: -1

Type %exit or %quit to exit IPython (%Exit or %Quit do so unconditionally).

所以发生这种情况是因为 _portaudio 无法导入。如果我尝试直接导入它:

In [2]: import _portaudio
------------------------------------------------------------
Traceback (most recent call last):
  File "<ipython console>", line 1, in <module>
ImportError: /Library/Python/2.6/site-packages/_portaudio.so: no appropriate 64-bit architecture (see "man python" for running in 32-bit mode)

好的，所以如果我export VERSIONER_PYTHON_PREFER_32_BIT=yes 然后再次运行 python(好吧，我想是 ipython)，我们可以看到它有效但会产生后果:

In [1]: import pyaudio

In [2]: pyaudio
Out[2]: <module 'pyaudio' from '/Library/Python/2.6/site-packages/pyaudio.pyc'>

我们可以假设 pylab 之前在工作!我花了一段时间才走到这一步，但有人可以帮助我完成这个安装或从成功的 Snow Leopard 安装中提供建议吗？抱歉发了这么长的帖子，但我因只提供部分信息而臭名昭著，我正在努力解决这个问题!

感谢 PyAudio 的作者对我的查询的快速响应，我现在有了一个安装良好的副本。他的指示在下面发布，供遇到类似问题的任何人使用。

Hi Michael,

Try this:

1) Make sure your directory layout is like:

./foo/pyaudio/portaudio-v19/ ./foo/pyaudio/

2) Build portaudio-v19 from sources, as you have done

3) cd ./foo/pyaudio/ 4) python setup.py build --static-link

(See the comments at the top of setup.py for more info on --static-link)

If all goes well, inside ./foo/pyaudio/build/lib.macosx-10.6-.../, you'll find the built (fat) objects comprising i386, ppc, and x86_64 binaries. You can also do a "python setup.py install" if you like.

Best, Hubert
