h5c++ can be used in much the same way MPIch is used to compile an HDF5 program. It takes care of specifying where the HDF5 header files and libraries are on the command line.
h5c++ supersedes all other compiler scripts in that if you've used one set of compiler scripts to compile the HDF5 C++ library, then
h5c++ uses those same scripts. For example, when compiling an MPIch program, you use the
Some programs use HDF5 in only a few modules. It isn't necessary to use
h5c++ to compile those modules which don't use HDF5. In fact, since
h5c++ is only a convenience script, you are still able to compile HDF5 C++ modules in the normal way. In that case, you will have to specify the HDF5 libraries and include paths yourself. Use the
-show option to see the details.
An example of how to use
h5c++ to compile the program
hdf_prog, which consists of modules
prog2.cpp and uses the HDF5 C++ library, would be as follows:
# h5c++ -c prog1.cpp
# h5c++ -c prog2.cpp
# h5c++ -o hdf_prog prog1.o prog2.o
