+ +Building Parallel HDF5
++When you build HDF5, you will need to build an version with parallel I/O +enabled. Here is a set of configure options that worked for us on a +Linux workstation running SuSE 10.1 with MPICH installed in /usr/local/mpich. +
+ ++./configure --prefix=/usr/local/hdf5-mpich --enable-parallel CC=mpicc CXX=mpicxx --disable-shared --enable-static --enable-stream-vfd ++ +
-
+
- --prefix=/usr/local/hdf5-mpich : the location where the HDF5 libs and +binaries will be installed. +
- --enable-parallel : contrary to the HDF5 documentation, which says that +"--enable-parallel" is optional for building the parallel version of +HDF5, you must have --enable-parallel to get the parallel-enabled +build. See these notes from HDF5 where they claim that +--enable-parallel is optional. +
- CC=mpicc CXX=mpicxx : contrary to the output from configure --help, the
+configure script seems to ignore the CC and CXX environment variables.
+We tried setting these environment variables to mpicc and mpicxx,
+respectively, and then ran configure with --enable-parallel. The configure
+script would faile with this error message:
+
+checking whether a simple MPI-IO program can be linked... no +configure: error: unable to link a simple MPI-IO application +
+
+ - --disable-shared and --enable-static: the HDF5 build failed for us +w/o these options when attempting to read symbols from libmpich.a. The +result of these options is that your parallel-enabled HDF5 libaries +will be static rather than dynamic. + +
