Welcome to HDF5 external filters

The external filter mechanism introduced with HDF5 1.8.12 allows applications to utilize custom filters not shipped by the HDF5 core library without recompiling your application. This repository provides external filters for HDF5 for

• the LZ4 compression algorithm
• BZip2 compression
• and the BLOSC library.

Installation

Currently the plugins must be built directly from the sources using cmake version 3 or higher. To build, use commands like these:

mkdir build
cd build
cmake .. -DENABLE_BITSHUFFLE_PLUGIN=yes -DENABLE_LZ4_PLUGIN=yes -DENABLE_BZIP2_PLUGIN=yes -DCMAKE_INSTALL_PREFIX=/usr/local
make install

For detailed information about the installation procedures for each module, consult the Readme files in the plugin subdirectories.

If you have a running WiX distribution installed on your Windows system MSI packages can be built. Currently the installation requires some manual intervention once the code is built (or even after an eventual MSI package has been installed).
