Question

I’ve reinstalled python3.2.2 interpreter from source on Linux Mint to add unicode support in curses and found out that PyQt4 library is not importing. I’ve tried to reinstall it, but got the same problem as here: PyQt4 for Python 3.2.2 failing to install on Linux Mint 12. So I’ve followed the answer of BlaXpirit and installed PySide, but it wasn’t importing too. Then I’ve found them both in /usr/lib/python3/dist-packages that wasn’t added to PYTHONPATH variable. I’ve added that dir and recieved next:

In [1]: import PySide

is okay, but:

In [2]: import PySide.QtCore
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-3-1c10ffe6e7d7> in <module>()
----> 1 import PySide.QtCore

ImportError: No module named QtCore

and PyQt4:

In [3]: import PyQt4
In [4]: import PyQt4.QtCore
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-5-e7e95ffb1113> in <module>()
----> 1 import PyQt4.QtCore

ImportError: /usr/lib/python3/dist-packages/PyQt4/QtCore.so: undefined symbol:       PyUnicodeUCS4_AsLatin1String

In PySide directory content is:

I’ve reinstalled python3 several times from repositories and python.org, from sources and binaries, and now I have 1 executable python3.2mu in /usr/bin and 3 (python3, python3.2, python3.2m) in /usr/local/bin.
Help me please!

Answer 1

solved the problem with PyQt4 by changing 65 line in pyatomic.h:

from

 _Py_ANNOTATE_HAPPENS_BEFORE(address);

to

_Py_ANNOTATE_HAPPENS_BEFORE(address) (void)address;
