Does anyone know if it's possible to build PyQt so that there is one shared
library that contains all the code instead of the 8 (libqtcanvascmodule.so,
libqtcmodule.so, libqtextcmodule.so, libqtnetworkcmodule.so,
libqtsqlcmodule.so, libqttablecmodule.so, libqtuicmodule.so,
libqtxmlcmodule.so) as there are today?
   

Building it as a single shared library shouldn't be too difficult. The problem 
is that I'm not sure Python can deal with several modules being defined in a 
single library as it uses the module name to load the extension and to call 
the initialisation function.

Why would you want to do this?

Python can deal with it, but only on windows platforms. There you can 
make a registry entry containing a module name as a key and the name of 
a DLL as the value. The Win32 extensions for Python use this feature:

[HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.2\Modules\pywintypes]
@=C:\\WINNT\\System32\\PyWinTypes22.dll
[HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.2\Modules\pythoncom]
@=C:\\WINNT\\System32\\pythoncom22.dll
C:\>python -v
...
>>> import pywintypes
import pywintypes # dynamically loaded from 
C:\WINNT\System32\PyWinTypes22.dll
>>> import pythoncom
import pythoncom # dynamically loaded from C:\WINNT\System32\pythoncom22.dll
>>>
