Hi, I ran through the tutorial and ran into a snag at the very end.
When I try to run

python configure.py –p win32-g++

from within my PyQt4 folder I get the following error:

Error: Make sure you have a working Qt v4 qmake on our PATH.

Does anyone know how to resolve this?

Thanks!

@notize: At the moment (and quite unfortunately), yes. But I hope to change that in the very, very near future. I am in the process of creating a stand-alone installer which has only the things necessary for Time Drive to run (Duplicity, PyQt, etc). I'm nearly there but I've never done an installer before and want to test it before I break anyone's machine. I will post a blog post about it as soon as it is ready.

I'm also waiting until the next iteration (0.2) is done and tested because it will support browsing and restoring older snapshots and clean up a few little things that don't quite work right, yet. The joys of young software, it still has all the sharp edges.

Do you mean that if I have 5 windows PC's in my household I have to do all these steps on everyone of them?

Is there a better/shorter way?

Thanks

Hello, thank you for your tutorial.
I follow it and can install all successfully but when i try to run 'from PyQt4 import QtCore' i get windows dialog error, it tell me:

pythonw.exe has encountered a problem and needs to close. We are sorry for the inconvenience.

First installation, i separate Qt folder and Python folder (PyQt4 and sip48 is in Qt folder) i get error, so i uninstall all of it and reinstall again by,
i create folder c:\Python_Qt then put both Qt and Python in this folder but it still show same error.

I MUST use C:\Windows folder same as you, right?
or something that i don't know?

i used:
qt-sdk-win-opensource-2009.02.1.exe
python-2.5.4.msi
PyQt4.zip
sip48.zip

if you know please tell me, Thank you.

Did a did a complete uninstall and then reinstall of everything and this is what I finally got to work.

Qt4 SDK 2009.02.1
Python 2.6.2
sip-4.8-snapshot-20090601
PyQt4 snapshot hosted on this site http://www.oak-tree.us/tutorials/PyQt4.zip

The first time around I installed everything under C:. The second time, I followed these instructions verbatim and installed to C:\Windows. I don't know if that really made a difference, but at least everything is working for me now. Thanks again for the post.

I appreciate this how-to. I followed these instructions and didn't appear to have an hitches with the installation. However, when trying to run "from PyQt4.QtCore import *" I receive the following error:
File "", line 1, in
ImportError: DLL load failed: A dynamic link library (DLL) initialization routine failed.

I'm running XP sp2 and have tried both Python 2.5 and 2.6.

Anyone else have this problem? Anyone have any luck solving it?

Thanks,
Regis

@Jason. I'd be happy to upload my version of the PyQt snapshot. You can find it at:

http://www.oak-tree.us/tutorials/PyQt4.zip

I spent a bit of time playing with other configurations early this event. In the process, I experimented with different versions of Python. For reasons I don't understand, I had issues with Python 2.5.4. (Though it worked flawlessly for me the first time I set up PyQt.) In a virtual machine with a clean Windows XP SP3 install, I was successfully able to compile and install with the most recent version of Python 2.6. However, your mileage may vary.

Maybe you also have the PyQt 4.5 snapshot by chance? I can find the Windows snapshot on the Riverbank website, but it doesn't seem to compile correctly. I have found one other user with the same issue in their mailing list (http://www.riverbankcomputing.com/pipermail/pyqt/2009-June/023134.html), but was posted just recently, so who knows if/when the issue will be resolved... It is annoying that Riverbank doesn't keep a short history of snapshots available.

Thanks

@Jason. You happen to be in luck, for I do have a copy of the sip48 snapshot code. I can't remember which version it is, but it successfully compiled and installed without issue. It is also the same version which I used to compile and install the PyQt snapshot.

If you are Windows Vista or Windows 7, make sure that you run all commands as an administrator. (Or if you are using XP, make sure that the commands are run from an administrator account.) I have verified that you can build and install this version of SIP on Windows XP, Windows Vista, and the release candidate of Windows 7.

Thank you. Nice article which is easy to follow.

Still, I ran into an issue...

At the current time, there are no SIP 4.8 snapshots available on the Riverbank website. I found one through GitHub at:
http://github.com/kevinw/sip/tree/master
by using the download button and choosing (.zip) for Windows, but the process failed at the make command. I then tried the stable 4.7.9 release and the make command was successful, but the install failed.

If you have a copy of the snapshot, could you provide a link to download it, or send a copy to my email?

Thanks. In the meantime, I will keep an eye on the Riverbank download page.
