<div dir="ltr"><div>Hi, where do precompiled binaries come from and how are they compiled? </div><div>Unfortunately very few people know about compilation on Windows (and one of the few recently moved to a different job :-( ). I remember encountering all kinds of funny problems running on Windows executables compiled with MinGW. They convert "/" to "\" in the directory name when a file is opened, but "C:" wasn't accepted, if I remember correctly. I am not sure whether a directory name containing "\" is considered to be valid, though. Natively compiled Windows binaries should accept the Windows syntax for directories, I guess. I know for sure (see the user guide) that it is possible to compile natively on WIndows using PGI 19.10.</div><div><br></div><div>Paolo<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Oct 20, 2020 at 11:54 AM Josh Lipton-Duffin <<a href="mailto:josh.liptonduffin@qut.edu.au" target="_blank">josh.liptonduffin@qut.edu.au</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p class="MsoNormal">Dear QE Developers,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I am a longtime ‘dabbler’ in QE, having not used the program in too much depth other than a few geometry optimisations. Up until recently I have always interacted with the package over a unix-like HPC cluster, but have recently found it
convenient to run small jobs on a windows desktop.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I am using the precompiled binaries (v6.3), and I have noticed that when composing the input file one must specify paths to output files, pseudopotentials, etc using the unix-style forward slash “/”, eg<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">pseudo_dir = "C:/Users/me/QE/pseudos"<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">however, this is syntactically incorrect on windows operating systems, as the accepted convention should use a backslash as a directory separator, eg.
<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">pseudo_dir = "C:\Users\me\QE\pseudos"<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">The real problem I am having is that Burai, the nice GUI from Japan will construct the input files using the latter convention; however, when pw.exe receives an input file with this structure it throws an error, unable to parse the directory.
This isn’t a problem for Burai on mac or linux platforms, since their directory delimiter is the same as unix.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Is it possible to have the windows binary (or, indeed all versions) to recognise either a backslash or a forward slash in the input file as a directory delimiter? I can see where this might cause problems in escaping characters properly,
but from an end-user standpoint it would be easier to move input files across different platforms if either character would work.<u></u><u></u></p>
