+************************************************************************
+ HDF5 Build and Install Instructions for Cygwin
+************************************************************************
+
+Preconditions:
+--------------
+
+1. Installed Cygwin 1.5.17 or higher
+
+ To install the Cygwin net release, go to http://www.cygwin.com and
+ click on "Install or update now!" icon. This will download a GUI
+ installer called setup.txt which can be run to download a complete
+ Cygwin installation via the internet. Then follow the instructions
+ on each screen to install Cygwin.
+
+ Cygwin uses packages to manage installing various software. Users can
+ choose to install or uninstall certain packages by running setup.exe.
+ http://www.cygwin.com/packages/ provides detailed information about
+ Cygwin packages.
+
+ To build HDF5 on Cygwin, Devel package (including gcc,gcc-g++,
+ gcc-g77, and gcc-java compiles, and gdb tool) should be installed.
+
+2. Compilers Installed
+
+ 2.1 C/C++ Compilers HDF5-1.8.0 Supported
+
+ gcc-3.4.4 is included in Cygwin, which includes:
+ gcc : GNU C compiler
+ gcc-g++: GNU C++ compiler
+ gcc-g77: GNU Fortran 77 compiler
+
+ 2.2 Fortran Compiler HDF5-1.8.0 Supported
+
+ HDF5-1.8.0 supports g95(GCC 4.0.1 (g95!) Jul 22 2005) and higher.
+
+ g95 is a free, open source Fortran 95 compiler. Users can
+ download the g95 binaries for Cygwin in the following website:
+ http://www.g95.org.
+
+ 2.3 Using Compilers Not Supported
+
+ The compilers in 2.1 and 2.2 are supported and tested by HDF
+ group. Any other compilers may still work but they are not
+ guaranteed by HDF group.
+
+ If users want to use other compilers except those in 2.1 and 2.2,
+ try to set the following variables to override the default
+ choices.
+
+ CXX : C++ compiler command
+ FC : Fortran compiler command
+
+ For example, if users want to use pgf90 as fortran compiler, then
+
+ setenv FC pgf90
+
+3. HDF5 Dependencies
+
+ 3.1 Zlib
+
+ zlib-1.2.2 or later is supported and tested on Cygwin.
+
+ 3.2 Szip
+ The HDF5 library has a predefined compression filter that uses
+ the extended-Rice lossless compression algorithm for chunked
+ datatsets. For more information about Szip compression and
+ license terms see
+ http://hdf.ncsa.uiuc.edu/HDF5/doc_resource/SZIP/index.html.
+
+ The latest supported public release of SZIP is available from
+ ftp://hdf.ncsa.uiuc.edu/szip/2.0. Binary distribution can be
+ found under ftp://hdf.ncsa.uiuc.edu/lib-external/szip/2.0/bin
+
+
+Install HDF5 on Cygwin
+----------------------
+
+1. Get HDF5 source code package
+ Users can download HDF5 source code package from HDF website
+ (http://hdf.ncsa.uiuc.edu).
+
+2. Unpacking the distribution
+
+ The HDF5 source code is distributed in a variety of formats which
+ can be unpacked with the following commands, each of which creates
+ an `hdf5-1.8.0' directory.
+
+ 2.1 Non-compressed tar archive (*.tar)
+
+ $ tar xf hdf5-1.8.0.tar
+
+ 2.2 Gzip'd tar archive (*.tar.gz)
+
+ $ gunzip < hdf5-1.8.0.tar.gz | tar xf -
+
+ 2.3 Bzip'd tar archive (*.tar.bz2)
+
+ $ bunzip2 < hdf5-1.8.0.tar.bz2 | tar xf -
+
+3. Configuring
+
+ Notes: See detailed information in hdf5/release_docs/INSTALL,
+ part 5. Full installation instructions for source
+ distributions
+
+ The host configuration file for cygwin i686-pc-cygwin is located
+ in the `config' directory and are based on architecture name,
+ vendor name, and operating system which are displayed near the
+ beginning of the `configure' output. The host config file influences
+ the behavior of configure by setting or augmenting shell variables.
+
+ In short,
+
+ 3.1 To configure HDF5 C Library, using
+
+ $ ./configure
+
+ 3.2 To configure HDF5 C/C++ Library, using
+
+ $ ./configure --enable-cxx
+
+ 3.3 To configure HDF5 C/Fortran Library, using
+
+ $ ./configure --enable-fortran
+
+ 3.4 To configure HDF5 C with Szip library, using
+
+ $ ./configure --with-szlib="path to szlib"
+
+ For example, if szip library was installed in the directory
+ /cygdrive/c/szip, which is parent directory of "include" and
+ "lib", then the following command will configure HDF5 C library
+ with szip enabled:
+
+ $ ./configure --with-szlib=/cygdrive/c/szip
+
+ 3.5 To configure HDF5 C without Zlib,
+
+ To disable zlib, using
+
+ $ ./configure --without-zlib
+
+ 3.6 Two ways to configure HDF5 C with specified Zlib
+
+ 3.6.1 Using
+
+ $ ./configure --with-zlib=INCDIR,LIBDIR
+
+ For example, if the zlib library is installed in
+ /cygdrive/c/usr, which is the parent directory of directories
+ "include" and "lib",
+
+ $ ./configure --with-zlib=/cygdrive/c/usr/include,/cygdrive/c/usr/lib
+
+ 3.6.2 Through the CPPFLAGS and LDFLAGS Variables
+
+ For example, if zlib was installed in the directory
+ /cygdrive/c/usr then using the following command to configure
+ HDF5 with zib
+
+ $ CPPFLAGS=-I/cygdrive/c/usr/include \
+ $ LDFLAGS=-L/cygdrive/c/usr/lib \
+ $ ./configure
+
+ 3.7 To specify the installation directories, using
+
+ $ ./configure --prefix="path for installation"
+
+ By default, HDF5 library, header files, examples, and
+ support programs will be installed in /usr/local/lib,
+ /usr/local/include, /usr/local/doc/hdf5/examples, and
+ /usr/local/bin. To use a path other than /usr/local specify
+ the path with the `--prefix=PATH' switch as in the above
+ command.
+
+ 3.8 Combination of Switches
+
+ All of the above switches can be combined together. For
+ example, if users want to configure HDF5 C/C++/Fortran
+ library with szip library enabled, with zlib library at
+ /cygdrive/c/usr/, and install HDF5 into directory
+ /cygdrive/c/hdf5 using gcc/g++ as C/C++ compiler and g95
+ as fortran compiler
+
+ $ ./configure
+ --with-szlib=/cygdrive/c/szip
+ --with-zlib=/cygdrive/c/usr/include,/cygdrive/c/usr/lib
+ --prefix=/cygdrive/c/hdf5
+ --enable-cxx
+ --enable-fortran
+ <"If no more switches, then hit Enter">
+
+ Notes: The command format above is for readilibity. In practice,
+ please type in the command above with at least one
+ space between each line, No "Enter" until users finish
+ the switches and want to run the configure.
+
+
+ or do it through CPPFLAGS and LDFLAGS variables:
+
+ $ CPPFLAGS=-I/cygdrive/c/usr/include \
+ $ LDFLAGS=-L/cygdrive/c/usr/lib \
+
+ $ ./configure
+ --with-szlib=/cygdrive/c/szip
+ --prefix=/cygdrive/c/hdf5
+ --enable-cxx
+ --enable-fortran
+ <"If no more switches, then hit Enter">
+
+4. Make and Make Check
+
+ After configuration is done successfully, run the following series of
+ commands to build, test and install HDF5
+
+ $ make > "output file name"
+ $ make check > "output file name"
+
+ Before run "make install", check output file for "make check", there
+ should be no failures at all.
+
+5. Make Install
+
+ $ make install > "output file name"
+
+
+6. Check installed HDF5 library
+
+ After step 4, go to your installation directory, there should be
+ three subdirectories: "bin" "include" and "lib".
+
+7. Known Problems
+
+ Shared libraries can not be built on Cygwin In release 1.8.0.
