That source is for PocketPC (ARMV4). I was able to compile it, but like I said, it's targeted to the ARM archetecture and won't run on an x86 machine.
I try to create an interface between RR and gmpc and i need to compile a dll writen with vc++ 2005.
I have found this source that is free here!
The name of the dll must to be 'Garmin.Native.dll'
Thanks for all help!!!
