h5cc - Online in the Cloud

PROGRAM:

NAME

h5cc - Helper script to compile HDF5 applications.

SYNOPSIS

h5cc [OPTIONS] <compile line>

DESCRIPTION

h5cc 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.

h5cc supercedes all other compiler scripts in that if you've used them to compile the HDF5
library, then h5cc also uses those scripts. For example, when compiling an MPIch program,
you use the mpicc script. If you've built HDF5 using MPIch, then h5cc uses the MPIch
program for compilation.

Some programs use HDF5 in only a few modules. It isn't necessary to use h5cc to compile
those modules which don't use HDF5. In fact, since h5cc is only a convenience script, you
are still able to compile HDF5 modules in the normal way. In that case, you will have to
specify the HDF5 libraries and include paths yourself.

An example of how to use h5cc to compile the program hdf_prog, which consists of modules
prog1.c and prog2.c and uses the HDF5 shared library, would be as follows:
# h5cc -c prog1.c # h5cc -c prog2.c # h5cc -shlib -o hdf_prog prog1.o prog2.o

OPTIONS

-help Prints a help message.

-echo Show all the shell commands executed.

-prefix=DIR
Use the directory DIR to find the HDF5 lib/ and include/ subdirectories. Default:
prefix specified when configuring HDF5.

-show Show the commands without executing them.

-shlib Compile using shared HDF5 libraries.

-noshlib
Compile using static HDF5 libraries [default].

<compile line>
The normal compile line options for your compiler. h5cc uses the same compiler you
used to compile HDF5. Check your compiler's manual for more information on which
options are needed.

ENVIRONMENT

HDF5_CC
Use a different C compiler.

HDF5_CLINKER
Use a different linker.

HDF5_USE_SHLIB=[yes|no]
Use shared version of the HDF5 library [default: no].
