Re: Unable to init function during import of debug version of extension

[Barry S. <ba...@ba...>]

In the vcproj file for example I have the following:

			<Tool
				Name="VCLinkerTool"
				AdditionalOptions="/export:initexample"

Make sure you are also have this /export:initcinterpreter in your  
vcproj file.
