I am have a problem when I am importing QtGui from PyQT4 inside Houdini's python.
import PyQt4 is without errors but the QtGui gives the same error: >>> from PyQt4 import QtCore Traceback (most recent call last): File "<console>", line 1, in <module> ImportError: /usr/lib/python2.6/dist-packages/PyQt4/QtCore.so: undefined symbol: _PyByteArray_empty_stri ng Houdini in my machine uses its own python2.6.4 and not system's python2.6.7 but Houdini's python calling pyqt4 from system's python with: *>>> import sys >>> sys.path.append('/usr/lib/python2.6/dist-packages')* * * and maybe thats the problem, the small difference between the two python versions. PyQt in stadard python works fine. Any idea why is this happening, how to fix it? Do I have to install python2.6.4 in my system also in order to much with Houdini's and if yes, which version of pyqt I should install? Does linux choose the right one based on the python installed in the system? cheers -- Christos Parliaros
