Hi,
I had a webmail problem so the answer below didn't go out to the mailing

Hi,
Mingcheng Chen, you'll need the 32bit version of MPICH2 as well. Otherwise
it doesn't make any sense!
As stated on the ParaView Developers mailing list, MS-MPI is a variant of
MPICH2. Additionally, the version of MS-MPI that is installed in Windows
x64 has libraries (DLLs) for 32 and 64bits. But with MPICH2, 32 and 64bit
are completely separate and independent installations.
Best regards,
Bruno

kind of building errors of paraview development version under Visual
Studio 2010 on Windows 7 64bits
Please keep the discussion on the mailing list so that everyone can
contribute and benefit. Also this discussion probably should have stayed on
the paraview users list so I'm cross-posting there.
I'm not certain if the 64 bit-ness of the MPI lib matters. It's certainly
safer to stick with a 32 bit version if you are compiling 32 bit code (and
64 bit for 64 bit libs), but it might not be required. Someone else on the
list may clarify.
In any case, the CMake FindMPI module we have has a rich and sordid history
behind it. It could just be buggy on your system. Try moving the cxx.lib to
the MPI_EXTRA_LIBRARY variable. I suspect it will build for you then.

Thanks David!
Before turning off PARAVIEW_USE_MPI, I still want to have a try.
I have installed MPICH2(64bit) on my machine. Is the 64bit version OK? And
I have set MPI_INCLUDE_PATH (According to online tutorial, it is not
MPI_INCLUDE, right?) and MPI_LIBRARY.
There is a small problem that CMake automatically sets MPI_LIBRARY to be
"C:\Program Files\MPICH2\lib\mpi.lib C:\Program Files\MPICH2\lib\cxx.lib".
So I have to manually split it into two separate lines for some projects in
the ParaView solution. Otherwise there will be several errors from those
projects, called "cannot open file 'C:\Program
Files\MPICH2\lib\mpi.lib C:\Program Files\MPICH2\lib\cxx.lib'."
Currently I am finding all the projects which needs such split by
compiling the whole solution again and again.

Turn off PARAVIEW_USE_MPI in CMake and recompile. If that doesn't work
(because of stale dependent build option settings) you will have to clear
out the build directory and recompile.
Alternatively you could install MPICH2 or OpenMPI for Windows and then
rebuild. When you turn on PARAVIEW_USE_MPI the first time, CMake should
find MPI in your path and and determine what the correct settings for
MPI_INLCUDE, MPI_LIBRARY and MPI_EXTRA_LIBRARY accordingly. The VTK and
ParaView dashboards have a few examples, but it appears the Kitware hosted
machines (see http://www.cdash.org/CDash/viewNotes.php?buildid=1886001for
example) all use Microsoft's MPI.

Hi everybody,
These days I was puzzled by different kinds of errors when I tried to
build paraview from open source code.
My machine is AMD64 and my OS is Windows 7 64bits.
My IDE is Visual Studio 2010.
My CMake is 2.8.
I choose to build a 32bit version.
A kind of errors is as follows.
"Error 31 error LNK1120: 12 unresolved externals
D:\LCSWorkSpace\ParaViewTest\ParaViewDev\bin\Release\Cosmo.dll Cosmo"
"Cosmo" is a project in ParaView.sln generated by CMake.
"D:\LCSWorkSpace\ParaViewTest\ParaViewDev" is my output directory of
CMake (where ParaView.sln is).
I do not know what the 12 unresolved externals are. Moreover, there is
another kind of errors such as follows.
"Error 29 error LNK2019: unresolved external symbol _MPI_Recv
referenced in function "public: void __thiscall
Message::receive(int,int)"
(?receive@Message@@QAEXHH@Z)
D:\LCSWorkSpace\ParaViewTest\ParaViewDev\VTK\Utilities\Cosmo\Message.obj
Cosmo"
Is it one of the 12 unresolved externals? What is the meaning of this
error and how can I get rid of it?
Thanks!
I am very interested in whether there are people who have successfully
built 32bit paraview using Visual Studio 2010 on 64bit machine.
Thanks again!
Best regards,
Mingcheng Chen
