************************************************************************
HDF5 Build and Install Instructions for MinGW
************************************************************************
Preconditions:
--------------
1. Installed MinGW (5.1.4 or higher) and MSYS (1.0.10 or higher)
To install the MinGW net release, go to http://www.mingw.org 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
MinGW installation via the internet. Then follow the instructions
on each screen to install MinGW.
2. Compilers Installed
2.1 C/C++ Compilers HDF5-1.8.1 Supported
gcc-3.4.2 is included in MinGW, which includes:
gcc : GNU C compiler
gcc-g++: GNU C++ compiler
2.2 Using Compilers Not Supported
The compilers in 2.1 are supported and tested by The 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,
try to set the following variables to override the default
choices.
CC : C compiler command
CXX : C++ compiler command
FC : Fortran compiler command
3. HDF5 Dependencies
3.1 Zlib
zlib-1.2.2 or later is supported and tested on MinGW.
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://hdfgroup.org/HDF5/doc_resource/SZIP/index.html.
Szip is currently not supported on MinGW, although we plan to add
support in the future.
Build HDF5 on MinGW
----------------------
1. Get HDF5 source code package
Users can download HDF5 source code package from HDF website
(http://hdfgroup.org).
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 `hdf5-1.8.1' directory.
2.1 Non-compressed tar archive (*.tar)
$ tar xf hdf5-1.8.1.tar
2.2 Gzip'd tar archive (*.tar.gz)
$ gunzip < hdf5-1.8.1.tar.gz | tar xf -
2.3 Bzip'd tar archive (*.tar.bz2)
$ bunzip2 < hdf5-1.8.1.tar.bz2 | tar xf -
3. Setup Environment
Building HDF5 1.8.1 requires an explicit link to libws2_32.a
to handle Windows Sockets. To do this, issue the command:
$ export LIBS=-lws2_32
Also, the default search path can cause trouble using ./configure in HDF5
1.8.1. Check that non-MinGW or non-msys directories are not added to the
PATH. You can do this by:
$ echo $PATH
If there are spurious entries, specifically those related to other Windows
compilers or tools, remove them by setting a new PATH without them. For
example,
$ export PATH=.:/usr/local/bin:/mingw/bin:/bin
4. Remove Unsupported Source
There are some projects which are built by default to test performance on
POSIX systems. They are irrelevent on MinGW, and can cause compiler errors.
To remove these projects from the build script, open ./perform/Makefile.in
Find all instances of "h5perf_serial", and remove them (along with their
respective extension or targets, if they exist). Then save the file.
5. Remove Tests
When building with MinGW, many tests must be removed from the
test suite run with "make check". This is because of the way
MinGW and Windows handles certain parsing. For example, MinGW
treats any command parameter starting with '/' as a path, and
replaces it with it's root directory on Windows, such as
'C:\msys\1.0\'.
To remove the tests, open the given 'Makefile.in' and edit the
line begining with "TEST_SCRIPT = " to remove the test script.
For example, to remove the "testerror.sh" from ./test/Makefile.in:
1) Open ./test/Makefile.in
2) Find the line "TEST_SCRIPT = $(top_srcdir)/test/testerror.sh"
3) Change it to simply read "TEST_SCRIPT =", and save.
Do this for the following Makefiles and tests:
- ./test/Makefile.in: "testerror.sh"
- ./tools/h5dump/Makefile.in: "testh5dump.sh" and "testh5dumpxml.sh"
- ./tools/h5diff/Makefile.in: "testh5diff.sh"
- ./tools/misc/Makefile.in: "testh5mkgrp.sh"
- ./tools/h5copy/Makefile.in: "testh5copy.sh"
- ./tools/h5ls/Makefile.in: "testh5ls.sh"
- ./tools/h5stat/Makefile.in: "testh5stat.sh"
6. Configuring
Notes:
1) Building Fortran libraries is also currently unsupported. This is
because the current release of gcc for mingw (3.4.5) is not compatible
with the current g95 for mingw (g95 0.91!, gcc version 4.0.3).
However, MinGW offers versions of gcc 4.x as a "Technology Preview"
or "Testing" release. These should be compatible with the latest
MinGW g95, but is untested. Keep in mind that this is UNSUPPORTED,
and any Fortran binaries build should be considered experimental.
2) Shared libraries can not be built on MinGW in release 1.8.1.
3) See detailed information in hdf5/release_docs/INSTALL,
part 5. Full installation instructions for source
distributions
In short,
To configure HDF5 with C Library, use
$ ./configure
If you would like to build the C++ library, add the parameter:
--enable-cxx
If you would like to build without the Zlib library, add the parameter:
--without-zlib
If you would like to specify the the Zlib library, there are two ways:
Using
--with-zlib=INCDIR,LIBDIR
For example, if the zlib library is installed in
/usr, which is the parent directory of directories
"include" and "lib",
--with-zlib=/usr/include,/usr/lib
Through the CPPFLAGS and LDFLAGS Variables
For example, if zlib was installed in the directory
/c/usr then using the following command to configure
HDF5 with zib
$ export CPPFLAGS=-I/usr/include
$ export LDFLAGS=-L/usr/lib
If you would like to specify the install directory, add the parameter:
--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.
Combination of Switches
All of the above switches can be combined together. For
example, if users want to configure HDF5 C/C++
library, with zlib library at /c/usr/, and
install HDF5 into directory /c/hdf5 using
gcc/g++ as C/C++ compiler:
$ ./configure
--with-zlib=/usr/include,/usr/lib
--prefix=/c/hdf5
--enable-cxx
<"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/usr/include \
$ LDFLAGS=-L/usr/lib \
$ ./configure
--prefix=/c/hdf5
--enable-cxx
<"If no more switches, then hit Enter">
7. 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.
8. Make Install
$ make install > "output file name"
9. Check installed HDF5 library
After step 4, go to your installation directory, there should be
three subdirectories: "bin" "include" and "lib".
