Question

我在尝试导入python模块pjsua时遇到以下错误。我有Mac OS 10.8.1版本。我验证了http://www.darrensessions.com/?p=292中提供的解决方案，解决方案似乎已在MacOS-10.7中修复了此问题。对于MacOS-10.8来说，这似乎再次被打破。编译代码时没有任何错误。导入PJSUA模块时仅获得以下错误。

>>> import pjsua
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "pjsua.py", line 59, in <module>
    import _pjsua
ImportError: dlopen(/Library/Python/2.7/site-packages/_pjsua.so, 2): Symbol not found: _AudioOutputUnitStart
  Referenced from: /Library/Python/2.7/site-packages/_pjsua.so
  Expected in: flat namespace
 in /Library/Python/2.7/site-packages/_pjsua.so

非常感谢你的帮助。谢谢，

一个直接的解决方案是（纯理论上，未经测试）：

查看http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2011-November/013722.html

请参阅补丁说明的地方：

# OS X Lion Support
if platform.mac_ver()[0].startswith("10.7"):
extra_link_args += ["-framework", "AudioUnit"]

更改行

if platform.mac_ver()[0].startswith("10.7"):

到

if platform.mac_ver()[0].startswith("10.7") or platform.mac_ver()[0].startswith("10.8"):

重新编译

- 编辑 -

好的，我按照我的建议修补了它：

> python ~/a.py 
a
> cat ~/a.py 
import pjsua

test = "a"
print test

最近修正了这个错误，如上面PJSIP 2.4 python包中所示：

# OS X Lion (10.7.x) or above support
    if version[0] == '10' and int(version[1]) >= 7:
        extra_link_args += ["-framework", "AudioUnit"]

有趣的是我遇到了同样的错误：

    macbookproloreto:python admin$ python samples/simplecall.py 
Traceback (most recent call last):
  File "samples/simplecall.py", line 23, in <module>
    import pjsua as pj
  File "/Library/Python/2.7/site-packages/pjsua.py", line 59, in <module>
    import _pjsua
ImportError: dlopen(/Library/Python/2.7/site-packages/_pjsua.so, 2): Symbol not found: _pj_atexit
  Referenced from: /Library/Python/2.7/site-packages/_pjsua.so
  Expected in: flat namespace
 in /Library/Python/2.7/site-packages/_pjsua.so

不明白为什么因为检查平台版本的Python setup.py脚本似乎没问题：

>>> import platform
>>> version = platform.mac_ver()[0].split(".")
>>> version
['10', '10', '4']
>>>
