Hi Erel, Long time since I've been here! I just got/installed V6 this afternoon and noticed a deficiency in my device that I figured I would create a program for - using the latest version. The app is basically a digital alarm clock that plays a song file when the alarm is triggered. That works fine. The error is when I try to compile the app for the device using the optimized compiler. Attached is a screen shot of the error I received. I have fmod.dll in the Basic4PPC Desktop directory, both FMODDesktop.dll (1.0.2860.24351) and FMODDevice.dll(1.0.2860.24334) in the apps directory. The Desktop version compiled fine with optimized compiling, but the device version failed. I was able to compile the device version WITHOUT the optimization option checked and it works fine on the device. Did I mess something up here? Or is it maybe a conflict with the V6? Any way, I thought I would post this so you could check it out... Happy New Year to you and yours!
