Hi there,
<div><br>
</div>
<div><br>
</div>
<div>As you probably know I develop the McStas code <a href="http://www.mcstas.org">
http://www.mcstas.org</a>, which has had a NeXus-output implementation for something like a decade.</div>
<div><br>
</div>
<div>In relation to a recent effort to output slightly more “Mantid friendly” output, I have had a look at the combination of McStas, Mantid and NeXus across platforms.</div>
<div><br>
</div>
<div>It turns out that for NeXus on Mac OS X I have the choice of either</div>
<div>* 4.3.0 <a href="http://download.nexusformat.org/kits/macosx/4.3.0/10.5-Leopard/NeXus-4.3.0.dmg">http://download.nexusformat.org/kits/macosx/4.3.0/10.5-Leopard/NeXus-4.3.0.dmg</a></div>
<div><span class="Apple-tab-span" style="white-space:pre"></span> - which is unfortunately 32bit only?</div>
<div>* 4.2.1 <a href="http://download.nexusformat.org/kits/macosx/old/NeXus-4.2.1.dmg">
http://download.nexusformat.org/kits/macosx/old/NeXus-4.2.1.dmg</a></div>
<div><span class="Apple-tab-span" style="white-space:pre"></span> - which is “fat binaries” including 32 and 64 bit for both Intel and PPC (the latter is long gone)</div>
<div><br>
</div>
<div>The last couple of OS X distros are pure 64bit, so the 4.3.0 is unfortunately not so useful. </div>
<div><br>
</div>
<div>It seems that maybe the Mantid folks are building their own distribution of NeXus on 64bit Mac OS - this is the status of the libs in the Mantid Third_party/lib repository:</div>
<div><br>
</div>
<div>willend@pkwi-mbp15:~/Projects/Mantid-git/mantid/Code/Third_Party/lib/mac64$ file libNeXus*<br>
libNeXus.0.dylib: Mach-O 64-bit dynamically linked shared library x86_64<br>
libNeXus.a: current ar archive random library<br>
libNeXus.dylib: Mach-O 64-bit dynamically linked shared library x86_64<br>

libNeXusCPP.0.dylib: Mach-O 64-bit dynamically linked shared library x86_64<br>

libNeXusCPP.dylib: Mach-O 64-bit dynamically linked shared library x86_64<br>
libNeXusCPP.la: libtool library file<br>
<br>
</div>
<div>May I suggest that a common effort is done with the Mantid folks to make a 64bit distribution available to people on the OS X platform?</div>
<div><br>
</div>
<div><br>
</div>
<div>Best,</div>
