If you are using CMake to build your project, just add:<br><br>TARGET_LINK_LIBRARIES(myExeOrLib vtkRendering)<br><br>after your ADD_EXECUTABLE or ADD_LIBRARY statement.<br><br>See "cmake --help-command TARGET_LINK_LIBRARIES" for more info.

<br>Dear David:<br><br>I am using CMake with the following configuration:<br><br>Source code: C:\VTK<br>build the binaries: C:\VTK\build<br><br>BUILD_EXAMPLES: OFF<br>BUILD_SHARED_LIBS:OFF<br>CMAKE_BACKWARDS_COMPATIBILITY:

<br><br>I think as you that some library is missing from the link.<br><br>In borland the path to library are placed using Project | Options |<br>Directories/Conditionals | Library path<br><br>Hear is the path C:\VTK\build\bin that contains the VTK libraries builded by

<br>><br>> That is the normal/expected VTK use.<br>><br>> If you have built VTK and want to use it *without* using CMake to drive<br>> the<br>> build of your project, then you have to add stuff to the Borland project
<br>> to<br>> enable including VTK header files and linking to VTK libraries.<br>><br>> As I am not a Borland GUI user, I do not know how to tell you to add a VTK<br>> library through Borland's GUI. Unresolved external errors mean that some
<br>> library is missing from the link line -- if you are using a CMake based<br>> project, this should just work; if you are using Borland's IDE/GUI then<br>> you<br>> are on your own... :-)<br>><br>> Any other Borland IDE users out there that can help Walter?
