VisIt avt Integration

TODO

General Information and Notes

This file is a site-config file that I used to build VisIt as a library for use with ParaView. To do so VisIt's makefiles had to be patched so that its GUI is excluded and ParaView's VTK can be used. The top section of the file is a set of notes as to how I configured VisIt's dependencies and VisIt itself. The bottom of this file is a bash script that VisIt uses to configure itself. You will have to modify the variables to reflect locations of the dependencies on your system. If you are only interested in a specific database plugin then you can skip many of the dependencies. You can't skip szip, silo, or hdf5. Be sure to point ParaView to the version of HDF5 you are using here when you build ParaView.

Notes:

VisIt suggests to use static libraries for its dependencies. This isn't always a good idea. HDF5 for instance should be shared when using with ParaView. Theses notes need to be updated to reflect this. TODO

Windows has a completely different build process because VisIt used visual studio. Mac is as of yet uncharted territory.

In theory one can build all of VisIt's dependencies using the "build_visit" script available from VisIt's web site. If you go that route, then you still should use this file to configure the patched VisIt with the ./configure line below.

You'll need to have Qt 3 development packge around somewhere because VisIt's ./configure script has a Qt 3 dependency.

It's best to try ot use the versions of the libraries I have used here, if not then second best is to use the ones recomended by VisIt. If you do niether you're on your own, but things will probably be OK as long as you stick to the recomended configuration.

Step 1: Build VisIt's dependencies

szip

LIBS=-lm CFLAGS=-fPIC CXXFLAGS=-fPIC ./configure --prefix=/opt/szip-2.1 --disable-shared
make -j 8
sudo make install

HDF4

LIBS=-lm CFLAGS=-fPIC CXXFLAGS=-fPIC ./configure --prefix=/opt/hdf4-4.2r3 --disable-fortran --with-szlib=/opt/szip-2.1/ 
make -j 8
sudo make install

HDF5

for gcc 4.3 you'll have to edit perform/zip_perf.c change line 549 to "output = open(filename, O_RDWR | O_CREAT, S_IRWXU);"

CFLAGS=-fPIC CXXFLAGS=-fPIC ./configure --prefix=/opt/hdf5-1.6.8_ser --disable-shared --disable-fortran --disable-parallel --with-szlib=/opt/szip-2.1 
make -j 8
sudo make install
sudo ln -s /opt/szip-2.1/lib/libsz.a /opt/hdf5-1.6.8_ser/lib/libsz.a

BoxLib

For gcc-4.3 add #include <cstdlib> to ParallelDescriptor.cpp Usiing gfortran instead of g77 works well.

cd into boxlib directory in the CCSEApps
edit GNUMakefile, set USE_MPI=false, COMP=g++
mv std std.old
chmod 644 *.H
CXXFLAGS=-fPIC CFLAGS=-fPIC FFLAGS=-fPIC make -j 8
sudo  mkdir -p /opt/boxlib/{include/2D,include/3D,lib}
sudo cp libbox3d.Linux.g++.f77.DEBUG.a /opt/boxlib/lib/libbox3D.a
sudo cp *.H /opt/boxlib/include/3D/
edit GNUMakefile,set DIM=2
CXXFLAGS=-fPIC CFLAGS=-fPIC FFLAGS=-fPIC make -j 8
sudo cp libbox2d.Linux.g++.f77.DEBUG.a /opt/boxlib/lib/libbox2D.a
sudo cp *.H /opt/boxlib/include/2D/

NetCDF

For gcc-4.3 add #include <cstring> to ./cxx/ncvalues.cpp

CXXFLAGS=-fPIC CFLAGS=-fPIC ./configure --prefix=/opt/netcdf-3.6.0-p1
make -j 8
sudo mkdir /opt/netcdf-3.6.0-p1
sudo make install 

Silo

4.6.2 doesn't work with VisIt and gcc 4.3 as of this writing(2009-02-25). Some sort of link issue, may be libtool.?

./configure --prefix=/opt/silo-4.6.1 --without-readline --with-hdf5=/opt/hdf5-1.6.8_ser/include/,/opt/hdf5-1.6.8_ser/lib/ --without-exodus --with-szlib=/opt/szip-2.1 --disable-fortran --disable-browser --disable-shared --disable-silex
make -j 8
sudo make install
sudo ln -s /opt/silo-4.6.2/lib/libsiloh5.a /opt/silo-4.6.2/lib/libsilo.a

CGNS

Only use hdf5 if you need it.
CXXFLAGS=-fPIC CFLAGS=-fPIC ./configure --prefix=/opt/cgns-2.4 --with-szip=/opt/szip-2.1/lib/libsz.a --with-hdf5=/opt/hdf5-1.6.8_ser/
make -j 8
sudo mkdir -p /opt/cgns-2.4/{include,lib}
sudo make install

CFITSIO

./configure --prefix=/opt/cfitsio
make -j 8
sudo make install

H5Part

CFLAGS=-fPIC ./configure --prefix=/opt/h5part-1.3.3 --with-hdf5path=/opt/hdf5-1.6.8_ser/
make -j 8
sudo make install

CCMIO

Didn't work & looks like it uses qmake ?!?. If some one complains we'll get it working.

GDAL

For gcc-4.3 download gdal-1.6.0, the following config works with both version

CFLAGS=-fPIC CXXFLAGS=-fPIC ./configure --prefix=/opt/gdal-1.6.0 --enable-static --disable-shared --with-libtiff=internal --with-gif=internal --with-png=internal --with-jpeg=internal --with-libz=internal --with-netcdf=no --without-jasper --without-python
make -j 8
sudo make install

Qt 3

We don't have to link against Qt but VisIt plugin system requires Qt to build.

export QTDIR=`pwd`
export LD_LIBRARY_PATH=$QTDIR/lib
./configure --prefix=/opt/qt-3.3.8
make -j 8
sudo make install

Step 2: Build VisIt

NOTE for now set VTK_USE_64BIT_IDS to OFF NOTE should we force the use of static libs when both shared and static are available? -Bstatic ??

patch -p6 < /home/burlen/ext/kitware_cvs/VisitPluginTool/VisItPV3Build.in.patch

./configure --prefix=/opt/VisIt-1.10.0 --with-config=/home/burlen/ext/kitware_cvs/VisitPluginTool/building_visit/vtkVisitDatabaseBridge.conf --with-hdf5=/opt/hdf5-1.6.8_ser/include,/opt/hdf5-1.6.8_ser/lib --enable-parallel --disable-scripting --disable-visitmodule --disable-viewer-mesa-stub --disable-icet --disable-bilib --disable-glew --disable-bzip2 --with-dbs=all

Step 3: Build the ParaView plugin

Building the database plugin for ParaView is a two step process, namely:

cd bin;
ccmake ../ ===> Set BOOTSTRAP to ON
make
ccmake ../ ===> Set BOOSTRAP to OFF
make

Step 1:

  BootstrapConfigure.
     During this pass a local copy of the VisIt libraries and database
     plugins are made. On Windows a copy of the "third party dependencies"
     is also made. This is done to facilitate the crossplatform build
     and configuration which is necessary due the large differences between
     the VisIt build system accross platforms, and to mitigate differneces
     in how various platforms handle shared libraries at run time. The final
     step of this pass is to generate the CMake files, ServerManager and 
     Pq xml for the vtkVisItDatabaseBridge plugin upon the VisIt configuration
     found.

Step 2:

  vtkVisItDatabaseBridge ParaView Plugin.
    During this pass the paraview plugin is built from the configuration
    generated during the first pass.

Windows

Configure PV for shared libs, using system HDF5. Point both ZLIB and HDF5 include and lib to HDF5 of VisIt/windowsbuild.
