h5fc [OPTIONS] <compile line>
h5pfc [OPTIONS] <compile_line>

h5fc and h5pfc subsume all other compiler scripts in that if you have used a set of scripts to compile the HDF5 Fortran library, then h5fc and h5pfc also use those scripts. For example, when compiling an MPICH program, you use the mpif90script. If you have built HDF5 using MPICH, then h5fc uses the MPICH program for compilation.

Some programs use HDF5 in only a few modules. It is not necessary to use h5fc and h5pfc to compile those modules which do not use HDF5. In fact, since h5fc and h5pfc are only convenience scripts, you can still compile HDF5 Fortran modules in the normal manner, though 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 h5fc to compile the program hdf_prog, which consists of the modules prog1.f90 and prog2.f90and uses the HDF5 Fortran library, would be as follows. h5pfc is used in an identical manner.

        # h5fc -c prog1.f90
        # h5fc -c prog2.f90
        # h5fc -o hdf_prog prog1.o prog2.o

When set, these environment variables override some of the built-in h5fc and h5pfc defaults.

The last three of these environment variables have corresponding variables with names ending in BASE that can also be set by editing their values in the "Things You Can Modify to Override HDF5 Library Build Components" section of the h5fcand h5pfc scripts.

Note that adding library paths to HDF5_LDFLAGS where another HDF5 version is located may link your program with that other HDF5 Library version.
