6. Installation¶
This section describes how to install the NeXus API and details the requirements. The NeXus API is distributed under the terms of the GNU Lesser General Public License version 3.
The source distribution of NAPI can be downloaded from the release page of the associated GitHub project. Instructions how to build the code can be found in the INSTALL.rst file shipped with the source distribution. In case you need help, feel free to contact the NeXus mailing list: http://lists.nexusformat.org/mailman/listinfo/nexus
6.1. Precompiled Binary Installation¶
6.1.1. Linux RPM Distribution Kits¶
An installation kit (source or binary) can be downloaded from: http://download.nexusformat.org/kits/
A NeXus binary RPM (nexus-*.i386.rpm) contains ready compiled NeXus libraries whereas a source RPM (nexus-*.src.rpm) needs to be compiled into a binary RPM before it can be installed. In general, a binary RPM is installed using the command
rpm -Uvh file.i386.rpm
or, to change installation location from the default (e.g. /usr/local) area, using
rpm -Uvh --prefix /alternative/directory file.i386.rpm
If the binary RPMS are not the correct architecture for you (e.g. you need x86_64 rather than i386) or the binary RPM requires libraries (e.g. HDF4) that you do not have, you can instead rebuild a source RPM (.src.rpm) to generate the correct binary RPM for you machine. Download the source RPM file and then run
rpmbuild --rebuild file.src.rpm
This should generate a binary RPM file which you can install as above. Be careful if
you think about specifying an alternative buildroot for rpmbuild by using
--buildroot
option as the “buildroot” directory tree will get remove (so
--buildroot
/ is a really bad idea). Only change buildroot it if the default
area turns out not to be big enough to compile the package.
If you are using Fedora, then you can install all the dependencies by typing
yum install hdf hdf-devel hdf5 hdf5-devel mxml mxml-devel
6.1.2. Microsoft Windows Installation Kit¶
A Windows MSI based installation kit is available and can be downloaded from: http://download.nexusformat.org/kits/windows/
6.1.3. Mac OS X Installation Kit¶
An installation disk image (.dmg) can be downloaded from: http://download.nexusformat.org/kits/macosx/
6.2. Source Installation¶
6.2.1. NeXus Source Code Distribution¶
The source code distribution can be obtained from GitHub. One can either checkout the git repositories to get access to the most recent development code. To clone the definitions repository use
$ git clone https://github.com/nexusformat/definitions.git definitions
or for the NAPI
$ git clone https://github.com/nexusformat/code.git code
For release tarballs go to the release page for the NAPI or the definitions. For the definitions it is currently recommended to work directly with the Git repository as the actual release is rather outdated.
Instructions how to build the NAPI code can be found either on the GitHub project website or in the README.rst file shipped with the source distribution.
