I’m trying to build a moderately sized Symbian Qt project (around 100 files) using the latest released Nokia Qt SDK (Qt 4.6.3 and Qt Mobility 1.0.2).

The build for the simulator finishes in under 3 minutes, but when I build for the device, the build takes well over 20 minutes! I can forget trying to debug on the device. It is very frustrating!

My machine specs are the following:
Windows 7 32-bit
3.24GB RAM
Intel Core 2 Duo 1.86GHz

The compiler has been stuck here for over 10 minutes:

    I solved the slow compilation problem as indicated by this thread
    http://discussion.forum.nokia.com/forum/showthread.php?196650-Selective-compiling&p=720040&viewfull=1#post720040

    I added

    SYMBIANBUILD_DEPENDENCYOFF = 1

    to the project environment variables (or it could be added to Windows environment variables), and the project compilation was back to speed again.
