This file contains instructions for the installation of HDF5 on
Unix-like systems. First, one must obtain a tarball of the HDF5
release from the ftp://hdf.ncsa.uiuc.edu/pub/dist/HDF5
repository. The files are available in uncompressed tar, gzip, bzip2,
and compress formats.
For those that like to live dangerously and don't like to read ;-) you
can do the following:
$ tar xf hdf5-1.0.0a.tar
$ cd hdf5-1.0.0a
$ make test
$ make install # Optional
Step 1. Unpack the source tree.
* The tarball will unpack into an hdf5-1.0.0a directory with one of
the following commands:
$ tar xf hdf5-1.0.0a.tar OR
$ gunzip <hdf5-1.0.0a.tar.gz |tar xf - OR
$ bunzip2 <hdf5-1.0.0a.tar.bz2 |tar xf - OR
$ uncompress -c <hdf5-1.0.0a.tar.Z | tar xf -
Step 2. Configure makefiles.
* HDF5 uses the GNU autoconf program for configuration. Most
installations can be configured by typing just (from the
hdf5-1.0.0a directory)
$ ./configure
* By default libraries, include files, programs, and documentation
are installed under /usr/local/lib, /usr/local/include,
/usr/local/bin, and /usr/local/man. However, if you want them
in some other location you can specify a prefix to use instead
of /usr/local. For instance, to install in /usr/lib,
/usr/include, /usr/bin, and /usr/man one would say
$ ./configure --prefix=/usr
Note: HDF5 can be used without installing it.
* You can also override detection of certain things with
environment variables:
CC Name of the C compiler to use.
CFLAGS Alternate C compiler flags.
CPPFLAGS Alternate C preprocessor flags.
MAKE Name of the make(1) program.
For instance it is common to specify the name of the C compiler,
C proprocessor flags, and compiler flags (add `env' to the
beginning of this command if you're running a csh-like shell)
$ CC=gcc CPPFLAGS=-DNDEBUG CFLAGS="-Wall -O3" ./configure
* The HDF team recommends the following C flags for this prototype
release of the library.
o Full warnings, usually `-fullwarn' or `-Wall' depending on
the compiler. With GCC you may optionally add:
-Wpointer-arith -Wwrite-strings -Wstrict-prototypes
-Wmissing-prototypes -Wmissing-declarations -Wnested-externs
o Symbol table, usually with `-g'
o Turn on debugging code in the various packages. Some
packages just produce extra output while others traverse
data structures looking for things that seem to be wrong.
-DH5AC_DEBUG - cache debugging
-DH5B_DEBUG - B-link-tree debugging
-DH5F_DEBUG - File debugging
-DH5G_DEBUG - Group debugging
-UH5O_DEBUG - Open/Close debugging (produces lots of output)
-DH5T_DEBUG - Data type conversion statistics
o The default low level driver can be chosen with
-DH5F_LOW_DFLT=H5F_LOW_STDIO - Use libc stdio.h functions
-DH5F_LOW_DFLT=H5F_LOW_SEC2 - Use system calls directly
the default is to use stdio functions.
* You can see a list of other configuration options by saying
$ ./configure --help
Step 3. Compile library, tests, and programs.
* Build library targets by saying
$ make
Note: If you supplied some other make command through the MAKE
environment variable in the previous step then use that command
instead. The same applies below.
Note: If you're re-building the library after changing some
files and you're not using GNU make and gcc, then you should say
`make clean' from the top directory between each build attempt
since the development Makefiles don't have complete dependency
information yet.
Note: When using GNU make you can add `-j -l6' to the make
command to compile in parallel on SMP machines.
Step 4. Run confidence tests.
* All confidence tests should be run by saying
$ make test
The command will fail if any test fails.
Note: some old versions of make will report that `test is up to
date'. If this happens then run `make _test' instead or run
`make test' from within the test directory.
Step 5. Install public files.
* Install the library, header files, and programs by saying:
$ make install
This step will fail unless you have permission to write to the
installation directories. Of course, you can use the header
files, library, and programs directly out of the source tree if
you like, skipping this step.
Step 6. Subscribe to mailing lists.
* Subscribe to the mailing lists described in the README file.
