1 Motivation

Rhdf5lib provides the C and C++ HDF5 libraries. It is primarily useful to developers of other R packages who want to make use of the capabilities of the HDF5 library directly in the C or C++ code of their own packages, rather than using a higher level interface such as the rhdf5 package. Using Rhdf5lib make life easier for users, as they do not have to worry about installing libraries at a system level, and for developers since they can work with a defined version of the library rather than developing strategies to cope with the potential for multiple versions.

Rhdf5lib is very much inspired by the zlibbioc and Rhtslib packages.*

2 Usage

There is an example package, usingRhdf5lib, that demonstrates how packages should link to Rhdf5lib.

2.2 Locating the library headers

In order for the C/C++ compiler to find the HDF5 headers during package installation, add Rhdf5lib to the LinkingTo field of the DESCRIPTION file of your package, e.g.

LinkingTo: Rhdf5lib

In you C or C++ code files, you can then use the standard include techniques, e.g., #include "hdf5.h" or #include "H5Cpp.h". You can inspect the header files manually to check their names and declared functions. To find their location on your system you can use the following code:

system.file(package="Rhdf5lib", "include")
## [1] "/tmp/Rtmp1HdP0H/Rinst31f27be44803/Rhdf5lib/include"
