<p>Comment (by Lucas Timotheo Sanches):</p>
<p>Hey Roland, sorry for the delay. Looks like the culprit is indeed <code>CPPFLAGS=-D_GNU_SOURCE</code>. Here are my compiler flags from simfactory’s optionlist file:</p>
<div class="codehilite"><pre><span></span>CFLAGS = -g -std=gnu11 -D_GNU_SOURCE -fcommon
CXXFLAGS = -g -std=gnu++11 -fcommon -fpermissive
F90FLAGS = -g -fcray-pointer -ffixed-line-length-none
</pre></div>
<p>I’m quite sure I’ve got this flag from one of the tutorials in the official site, but now I cant seem to find the exact page that recommends it <img class="emoji" src="https://pf-emoji-service--cdn.us-east-1.prod.public.atl-paas.net/standard/551c9814-1d37-4573-819d-afab3afeaf32/48x48/1f615.png" alt="😕" title=":confused:" data-emoji-short-name=":confused:" />. I’ve managed to use the toolkit successfully with it for some time now but always with the system provided HDF5. I’ve decided to try the bundled version to solve an error that in the end hadn't anything to do with the HD5F lib being used and stumbled upon this.</p>
<p>Also, as you’ve asked, my output of <code>cat /etc/os-release</code></p>
