<p>Just out of curiosity, what's wrong with just using the Visual
Studio Community compiler? I reckon they are be agnostic towards
hardware and will not "accidentally" cause worse performance when
executing your build on an AMD processor.<br>

HI Folks
<div class=""><br class="">
</div>
<div class="">Following from a DIALS issue about it being slow on
Windows</div>
<div class=""><br class="">
</div>
<div class=""><a href="https://github.com/dials/dials/issues/1666"
class="" moz-do-not-send="true">https://github.com/dials/dials/issues/1666</a></div>
<div class=""><br class="">
</div>
<div class="">I have fallen into a rabbit hole and I am trying to
build DIALS (and hence cctbx) on Windows with the intel
compilers from oneAPI - however I keep stumbling over linking
errors with e.g. undefined symbol __floor</div>
<div class=""><br class="">
</div>
<div class="">Should I abandon hope or has someone done this? </div>
<div class=""><br class="">
</div>
<div class="">I know this is not a new path to tread as
windows_icc was a defined combination on the SConscripts</div>
<div class=""><br class="">
</div>
<div class="">I had had to hack some bits around a little
presumably to accommodate 2021 versions of icc compilers, but
this felt like I was going down a bad path</div>
<div class=""><br class="">
</div>
<div class="">Would welcome input from anyone who can help -
currently windows DIALS is a pretty poor relation</div>
<div class=""><br class="">
</div>
<div class="">It is noteworthy however that parallel operation
does now appear to work on Windows with easy mp :-)</div>
<div class=""><br class="">
</div>
<div class="">In other news - has anyone considered adding clang
support with clang coming from conda? Could make for more
consistency in the builds… I had a look at how one may go about
doing this but rapidly found myself in SCons hell. </div>
<div class=""><br class="">
</div>
<div class="">Thanks in advance for any help & all the best
Graeme</div>
