Rev 674

On Linux machines using PyQt4.2, there is a bug that causes vtk pipelines not to show on the spreadsheet. Solution: edit the file path_to_vistrails_src/vistrails/packages/vtk/

in the import section (around line 27), add

 import sip

replace line 244:

 vp = '_%s_void_p' % (hex(int(QtGui.QX11Info.display()))[2:])


    vp = '_%s_void_p' % (hex(int(QtGui.QX11Info.display()))[2:])
except TypeError:
    #This was changed for PyQT4.2
    if isinstance(QtGui.QX11Info.display(),QtGui.Display):
        display = sip.unwrapinstance(QtGui.QX11Info.display())
        vp = '_%s_void_p' % (hex(display)[2:])

Rev 559

There are two issues with the binary version of this release.

1. When the current directory is not on the PATH. This causes VisTrails to raise a Requirements not fulfilled exception.

Solution: Adding '.' or path_to_vistrails_install/vistrails to the PATH solves this problem.

2. When installing on a non-english system or on a custom directory, VisTrails won't start. This is due to absolute paths inside the bookmarks file.

Solution: Remove file bookmarks.xml inside ~/.vistrails folder. On Windows XP it's located on C:\Documents and Settings\your_username\.vistrails. On Windows Vista, it's located at C:\Users\your_username\.vistrails.
