[Paraview] Is There An Error In vtkSocketCommunicator (2.4.2)?

[Kent Eschenberg]

I can't tell whether this is a bug or another dumb thing I've done. 
Compiling a fresh download of 2.4.2 on a Fedora Core 4 system (cmake 
2.2-patch 2, gcc 4.0.2) with no changes yields the following error:

======
.../VTK/Parallel/vtkSocketCommunicator.cxx:
In member function
virtual int vtkSocketCommunicator::GetPort(int):
error: invalid conversion from int* to socklen_t*
======

At the top of this routine are the lines

======
#if defined(VTK_HAVE_GETSOCKNAME_WITH_SOCKLEN_T)
  socklen_t sizebuf = sizeof(sockinfo);
#else
  int sizebuf = sizeof(sockinfo);
#endif
======

and the only line in CMakeCache.txt that includes the flag is

======
VTK_HAVE_GETSOCKNAME_WITH_SOCKLEN_T:INTERNAL=1
======

So, "&sizebuf" is an "int*" and gcc doesn't know how to convert it to 
"socklen_t*".

On a hunch I tried merely re-running cmake then make. None of the files 
from the first cycle were changed. This worked without problems.

What do you think is wrong?

Thanks!
