[ITK] [ITK-users] ITK 4.8.1 build on Cygwin

[Andrew J. Buckler (Elucid Bioimaging)]

Hello,
I am working to build ITK 4.8.1 on Cygwin, but receive the following error:
/cygdrive/c/Users/Andrew Buckler/My Documents/projects/InsightToolkit-4.8.1/Modules/ThirdParty/KWSys/src/KWSys/SystemTools.cxx: In function 'void Realpath(const string&, std::string&, std::string*)':
/cygdrive/c/Users/Andrew Buckler/My Documents/projects/InsightToolkit-4.8.1/Modules/ThirdParty/KWSys/src/KWSys/SystemTools.cxx:326:51: error: 'realpath' was not declared in this scope
   char *ret = realpath(path.c_str(), resolved_name);

I had run cmake beforehand, using the following:
$ cmake -DCMAKE_CXX_FLAGS=-std=c++11 -DCMAKE_PREFIX_PATH=../VTK-build -DModule_ITKReview:BOOL=ON -DModule_MinimalPathExtraction:BOOL=ON -DModule_ITKVtkGlue:BOOL=ON ../InsightToolkit-4.8.1

Which ran successfully.

As it happens, I did have what seems the same error building VTK.  A request to that list elicited a most helpful message from Cory, pointing me to http://hvrl.ics.keio.ac.jp/kimura/vtk/vtk-6.3.0.html which included a patch and instructions that cleared the problem.  Before posting this message to the list, I did ask Cory whether he had or knew of a similar fix for ITK, but he replied suggesting I post to this list (apparently indicating that he had more specific experience on this point for VTK than ITK).

Any help would be most wlecome, with my thanks.

Happy Halloween,
Andy
