On win7/x64. Installed dng sdk and all dependencies per the readme files. xml sdk built OK with vc10 express, as 64 bit static and dll.
But the vc solution for dng_validate has incorrect names for the xml sdk build projects, so it cannot find those components. Specifically it looks for "..\..\..\xmp_sdk\build\vc\XMPCore.vcxproj". the actual paths in the xmp sdk are different and longer, like "..\..\..\xmp_sdk\build\vc10\dynamic\windows_x64". Moreover there is no XMPCore.vcxproj there.
I suppose the real problem may be that the dng sdk project is trying to build it as .net managed code, while the xml sdk was built as open code. So I guess what I am looking for is a way to build the dng sdk open.
