For some reason autoconf seems to pick up version 1.10.2 instead of 1.8.20 ``` checking for HDF5 libraries... yes (version 1.10.2) ``` Mabe some path is wrong?

Hi Hans-Peter, a quick profiling exercise suggests that most of the time (80%) is spent in the `$close_all()` call: ```R Rprof("issue-92-hdf5r.out", line.profiling=TRUE) h5file

The problem seems to be the version of miniconda you are linking to, see also #113.

As far as I remember h5 stores NA strings as `"NA"`and converts them to `NA_character_` when reading back.

Hi Michael, I just revisited the issue and found that 1. Opening datasets in **hdf5r** is significantly slower than **h5** - as Holger already mentioned R6 object instantiation in H5GTD_factory...

According to your first line, the problem seems to be the miniconda hdf5 version: ``` checking for h5cc... /miniconda/bin/h5cc ``` Try to link to `libhdf5-dev` directly.

Well, we should maybe state it in the readme since the issue seems to be quite common.

That sounds really interesting!!! Would like to contribute to that one! > Am 27.10.2017 um 05:56 schrieb hhoeflin : > > — > You are receiving this because you are...

Any updates on this?
