Description
CMake 2.0.6 is not able to properly link VTK when compiling with gcc 4. A post on the vtkusers mailing list [1] indicates that the problem is due to the CMake module file CMakeDefaultMakeRuleVariables.cmake. This file explicitly adds "-lgcc" to the linker command line, and that causes problems with Apple's gcc. If that extra item is removed, then compilation proceeds without any trouble. An attached patch removes the explicit link.
The larger issue is whether this is an obscure bug in Apple's gcc implementation, as it appears with several other open source packages as well. (See BUG #3032, for example.) I am not familiar with smpeg, but maybe the resolution it implemented can be applied for CMake and/or VTK? I also tried the approach recommended in BUG #2927, but it did not resolve this error.
