[Paraview] build ParaView git on Windows7 64bit + MSVC2010 with vtkPythonCore errors

Wed Feb 16 08:05:13 EST 2011

Hi David and Rob,
Just want to add another data point.
I have rebuild ParaView from git source with MSVC2008 instead. Everything else is the same with what I was reporting before. Enthought Python 7.0.1 64bit is used. All the python flags in Cmake are turned on. PYTHON_DEBUG_LIBRARY is left empty accompanied with modified C:/Python27/include/pyconfig.h as following, i.e. assigning python27.lib as the debug library instead of default python27_d.lib.

                /* For an MSVC DLL, we can nominate the .lib files used by extensions */
#ifdef MS_COREDLL
#             ifndef Py_BUILD_CORE /* not building the core - must be an ext */
#                             if defined(_MSC_VER)
                                                /* So MSVC users need not specify the .lib file in
                                                their Makefile (other compilers are generally
                                                taken care of by distutils.) */
#                                             ifdef _DEBUG
#                                                             pragma comment(lib,"python27.lib")//"python27_d.lib")
#                                             else
#                                                             pragma comment(lib,"python27.lib")
#                                             endif /* _DEBUG */
#                             endif /* _MSC_VER */
#             endif /* Py_BUILD_CORE */
#endif /* MS_COREDLL */

The entire build went smoothly. And now I have a running (Debug) paraview package! Another interesting thing to be noted is with "VTK_WRAP_PYTHON_SIP". When it is enabled, CMake looks for sip installation in the system. However, current SIP source distribution for windows
http://www.riverbankcomputing.co.uk/software/sip/download
does not have 64bit windows specs. There is only win32-msvc2008 variation as the closest match. That creates a 32bit installation instead. And vtkCommonPythonSIP(D) projects cannot be built due to incompatible libraries...

Best,
x

Hi Dave and All,
I got some progress in terms of building vtkPythonCore. I had Enthought's Python distribution ver 7.0.1 !!!64bit!!! initially. I have verified it is indeed a 64bit Python executable. The package comes with python27.lib and CMake did not blink and automatically set PYTHON_LIBRARY to that lib. However, during building, MSVC2010 kept reporting "python27.lib" cannot be found.
Now, the fun part, I uninstalled Enthought distribution and tried "Python 2.7.1 Windows X86-64 Installer" from
http://www.python.org/getit/
This time, MSVC2010 no longer complained about missing "python27.lib". I am left with errors like

Error    1          error LNK2001: unresolved external symbol __imp__invalid_parameter_noinfo_noreturn            C:\ParaViewGit_VS2010\VTK\Wrapping\Python\vtkPythonUtil.obj           vtkPythonCore

After a bit digging, the error has something to do std::vector. Here are the beginning lines of vtkPythonUtil.cxx

#include "vtkPythonUtil.h"
#include "vtkPythonOverload.h"

#include "vtkSystemIncludes.h"

#include "vtkObject.h"
#include "vtkSmartPointerBase.h"
#include "vtkWeakPointerBase.h"
#include "vtkVariant.h"
#include "vtkStdString.h"
#include "vtkUnicodeString.h"
#include "vtkWindows.h"
#include "vtkToolkits.h"

#include <vtksys/ios/sstream>
#include <vtkstd/map>
#include <vtkstd/vector>
#include <vtkstd/string>
#include <vtkstd/utility>
       ...

After I move "#include <vtkstd/vector>" to the top of the file, POW! vtkPythonCore is successfully built. So I guess #include <vector> in vtkstd/vector.h gets undefined somewhere by those headers listed before it. Not sure whether it is a bug for other people.

Hi David,
I am out of luck.
Just did a fresh CMake configure with PARAVIEW_ENABLE_PYTHON on and the same PYTHON_LIBRARY value. The errors from MSVC2010. Any other suggestions?
Best,

Hi Xunlei,

What do you have the PYTHON_LIBRARY cmake option set to? If you set that correctly then it should be able to link properly. For example this is what it is set to on my machine.

C:/Support/Python27-x32/libs/python27.lib

Hello,

PARAVIEW_ENABLE_PYTHON and VTKMY_WRAP_PYTHON in my CMake. I also built Python 2.7.1 64bit from source so that I have both python27.lib and python27_d.lib available. However the core python related projects are failed to build in both Debug and Release builds. Then the effects just trickled down like crazy. Below are 3 major errors in Debug build I feel might be the primary errors. And I do link python27_d.lib for all of them. Please see the attached CMakeLists.txt for more details.

Error      6              error LNK1104: cannot open file 'python27.lib'                C:\ParaViewGit\Utilities\VTKPythonWrapping\Executable\LINK               vtkPVPythonInterpretor

Error      3              error LNK1104: cannot open file 'python27.lib'    C:\ParaViewGit\VTK\Wrapping\LINK      vtkWrapPython

Would you please help me? Thanks a lot.

Best,
