[Qt-interest] 答复: Can not load qsqlite4.dll

[吴海峰]

Yes. I have tried the instructions described in the link you provided already yesterday. But no lucks.

So in the previous mail, I use QPluginLoader to check whether the qsqlite4.dll can be loaded.
The result is that it produced the output "Program is not installed correctory. Reinstalling it may fix the problem", which is caused by the missing of manifest file according to MSDN. But the qsqlite plugin is compile with the mainfest embed mode. I wander why it still produce the result which was caused by the missing of manifest file. Actually it is involved.

I also struggled to make this work.  There was no problem when I was
developing my app in Visual Studio, but when I tried to deploy /
install it, I had the same problem you describe.

Have you copied the plugin into the Plugins directory in your
executable directory (win) or app bungle (mac)?  Have you reviewed all
the documents about deploying Qt applications with plugins?  The info
is here:
Win: http://doc.trolltech.com/4.5/deployment-windows.html#qt-plugins
Mac: http://doc.trolltech.com/4.4/deployment-mac.html#qt-plugins
