Hi, as stated in the title, my update to Qt SDK 1.2 has somehow undefined Q_OS_SYMBIAN and Q_WS_S60. I had a previous Qt SDK installation 1.1.4, which I tried to preserve by installing the new SDK to a folder named QtSDK_1_2. Here's the weird part. These constants are now undefined in both environments, the old and the new. It looks like the new installation overwrites the previous shortcuts to point them to the new SDK. Has anyone else encountered this problem? How can I restore these constant definitions? (I found an earlier thread on this but it's not related to the 1.2 installation.)
