      I'm trying to compile and build the "Reading from a .skp file" example found at http://www.sketchup.com/intl/en/developer/su-api/

      What I did:

      1. Installed Visual Studio C++ 2010 Express
      2. Downloaded the SDK
      3. Created a blank Win32 Console app and copied the example into it.
      4. Among the project settings set the location for the sdk header and lib files.
      5. Added #include "stdafx.h" as the first line of the example code.
      6. Tried to build.
      7. Got a list of errors:
      
      d external symbol __imp__SUTerminate referenced in function _main
      1>skp demo.obj ; error LNK2019; unresolved external symbol __imp__SUModelRelease referenced in function _main
      1>skp demo.obj ; error LNK2019; unresolved external symbol __imp__SUStringRelease referenced in function _main

      1>skp demo.obj ; error LNK2019; unresolved external symbol __imp__SUStringCreate referenced in function _main
      1>skp demo.obj ; error LNK2019; unresolved external symbol __imp__SUVertexGetPosition referenced in function _main

      1>skp demo.obj ; error LNK2019; unresolved external symbol __imp__SUEntitiesGetFaces referenced in function _main
      1>skp demo.obj ; error LNK2019; unresolved external symbol __imp__SUEntitiesGetNumFaces referenced in function _main

      1>skp demo.obj ; error LNK2019; unresolved external symbol __imp__SUInitialize referenced in function _main
      1>c;\users\user1\documents\visual studio 2010\Projects\skp demo\Debug\skp demo.exe ; fatal error LNK1120; 17 unresolved externals
      ========== Build; 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
      
      

      The error messages obviously refer to the implementation of these functions are not found in the library files. I tried to copy the SDK libraries (.lib, .dll) to any directory I could imagine in the search path but still got the same error list on build.

      Any ideas what needs to be done to successfully compile and build the example?

        Generally, its better to amend the VS library search path rather than have multiple copies of libs/dlls

          Thank you AdamB. I did add the path of the downloaded .dll and .lib to the VS library search path.
          Somewhere I read that character encoding differences could cause such error messages. So I also tried to change the project's encoding settings without any luck....

          EDIT: Thank you. SUCCESS!!! (Well it was a missing reference to the lib... 😳 )
