[IGSTK-Users] Error compiling the current cvs version on linux

[Karthik Krishnan]

Hi Yair, Patrick,

You've compiled ITK just fine. This is a bug in
igstkToolCalibrationReader.txx .

The correct way this file should've included zlib is
   #include "itk_zlib.h"    or   #include "vtk_zlib.h"
not
   #include "zlib/zlib.h"

The problem with including "zlib/zlib.h" is that IGSTK will fail to build
1.  against installed ITK/VTK. since they don't install the zlib.h header
file in "zlib/zlib.h".
2.  if ITK and VTK were compiled so as to use system zlib.

HTH,

PS:
The header file itk_zlib or vtk_zlib picks the appropriate zlib library
based on whether you'd compiled ITK/VTK asking the libraries to pick the
system zlib or the zlib provided with the library.
