Compile single plugin to be 32-bit, while rest of app and plugins are 64-bit

[dovy]

I am curious if it is at all possible to have a 64-bit QT Desktop application compiled for 64-bit, but compile and package a 32-bit plugin to read and write a specific file format?

Any guidance would be greatly appreciated. Thank you.

No, this is not possible, at least on "Windows":http://stackoverflow.com/questions/2265023/load-32bit-dll-library-in-64bit-application

Well, you can do a hack: create very simple plug-in in 64 bits which call an 32 bits application. You will need to use one of the "Inter-Process Communication":http://doc.qt.digia.com/latest/ipc.html method. 32 bits application will read and write a specific file format.
