The libraries are threadsafe and can be used in omp-parallel codes. To see configure-details on the installed libraries, load a hdf5-module and issue cat $HDF5DIR/libhdf5.settings!
Modules and Prerequisites
- module avail hdf5 shows all available hdf5 versions
- module show <modulename> shows environment variables set when loading the module
- module help <modulename>shows some details on compilers and MPI
...
- readelf -a $HDF5DIR/libhdf5_hl.so | grep RPATH
Linking the hdf5-libraries in user programs
Loading a hdf5-module does not link the libraries automatically, when compiling some other software. hdf5 does not deliver any standard way to detect the path to the libraries like pkg-config. So you have to configure Makefiles or install-scripts "by hand". The environment variables exported by the modules should allow short and flexible notation.
hdf5-modules do not have any effect during the runtime of your binaries. If the hdf5-libraries are linked dynamically, it is recommended to set RPATH in the binary. Otherwise the hdf5-libraries (and others) will not be found, during runtime. This can be done with the compiler option -Wl,-rpath=$LD_RUN_PATH, which passes the rpath to the linker.
hdf5 compiler wrapper
The compiler wrapper h5cc, h5fc (parallel h5pcc and h5pfc) can be used to build programs linking the hdf5-libraries. These wrappers set rpath for all libraries to be linked dynamically for hdf5.
