Re: [PyQt] Problem freezing a Sqlite based PyQT app
I actually had nothing but problems with PyInstaller. In my instance, I am using Twisted + PyQt4 in my app, so I could never even get it to run while frozen. Not to mention it seems to want to pickup every dll in my system to package it into my app (like kernel32.dll). You can manually copy the Qt plugins folder, since you should only need to do this once unless you delete the dist folder each build (that gets annoying quick). I know theres no support for implicit dependencies, but you can explicitly define them in the setup script (or you can use something like Gui2Exe).

2010/1/11 Anil ani...@atlastooling.com.au Have you included sqldrivers folder in to your package?

Claudio ___ PyQt mailing list p...@riverbankcomputing.comhttp://www.riverbankcomputing.com/mailman/listinfo/pyqt -- Thanks Anil, it worked just fine! Just complementing for those who face the same problem in the future, I had to copy the C:\Python26\Lib\site-packages\ PyQt4\plugins\sqldrivers dir to my frozen app target-dir. The only file needed in my case was qsqlite4.dll (which refers to QSqlite), but it has to be in a folder named ''sqldrivers'' into the target-dir for the app to work.
