Hi Robert, To use MPIR in a Visual Studio project you have to do two things. First you have to include "mpir.h" as you have done. Second, you have to add the relevant MPIR library to your project. It seems likely that you have not done the latter. Assuming that you are using the static library (mpir.lib), you need to add this to your solution by using the Visual Studio 'Properties' dialogue (an option when you right click on your solution in the Solution Explorer). You need to find the location of the library (e.g. lib\win32\release\mpir.lib) and add it to the 'Linker|Input|Additional Properties' item. Alternatively, right click on your solution in the Solution Explorer, select 'Add|Existing item', navigate to the library in the file dialogue and select it to add it to your project. I hope this helps, if not just get back to me and I will see what I can do to help further. Brian -- You received this message because you are subscribed to the Google Groups "mpir-devel" group.
