Hi, As you know, the WDK 8 use VS2012 to build the driver. In order to build an APO we need to dynamically link to the CRT because of the lib "AudioBaseProcessingObject.lib". In the previous WDK it used to generate an APO.DLL which dynamicaly link to the MSVCRT.DLL (the one from the OS). Now with the WDK 8, the generated APO needs the MSVCRT100.DLL (from VisualStudio). Is there a way to avoid that? How can I force the link to the static CRT or the dynamic OS-CRT? Is it acceptable to deliver the VS-CRT inside the driver package? Thank you.
