Description

I had tried several ways to install hdf5 on torch, but always get an error when I require 'hdf5' in torch:

/home/azyl99/torch/install/share/lua/5.2/trepl/init.lua:389: /home/azyl99/torch/install/share/lua/5.2/hdf5/ffi.lua:29: could not load library /usr/local/lib/libhdf5.a

Research direction

Start with the failing require 'hdf5' entry point and hdf5/ffi.lua:29, where the error reports that /usr/local/lib/libhdf5.a cannot be loaded. Reproduce the require in the reported Torch/Lua environment and determine the expected library path; done means the hdf5 module loads without this error.
