Examples – SoundTouch DLL ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Examples – SoundTouch DLL ,[object Object],PRJ_PLATFORMS DEFAULT PRJ_EXPORTS ..ncoundTouch.h ..ncFIFOSamplePipe.h ..ncTTypes.h PRJ_MMPFILES SoundTouch.mmp

Examples – SoundTouch DLL ,[object Object],TARGET SoundTouch.dll TARGETTYPE dll UID 0x1000008D 0x0839739D CAPABILITY ReadUserData USERINCLUDE ..nc SYSTEMINCLUDE poc32nclude poc32ncludetdapis SYSTEMINCLUDE poc32ncludetdapisys SYSTEMINCLUDE poc32ncludetdapistlport SOURCEPATH ..rc SOURCE SoundTouch.cpp SoundTouchDllMain.cpp AAFilter.cpp SOURCE FIFOSampleBuffer.cpp FIRFilter.cpp SOURCE RateTransposer.cpp TDStretch.cpp LIBRARY euser.lib LIBRARY libc.lib libm.lib libstdcpp.lib

Examples – SoundTouch DLL ,[object Object],[object Object],[object Object],[object Object],[object Object],throw std::runtime_error("Illegal number of channels"); Code like this: Should compile by simply including <stdexcept> but <string> is needed as well. The string header should be included internally by <stdexcept> but it seems there is a bug in the Symbian version of STLport… With <string> included in the relevant files it compiles for all build targets.
