[mcstas-users] Mac OS X Yosemite and McStas: Hold your horses!

[Peter Kjær Willendrup]

Dear all,


A tested download bundle for Mac OS X 10.10 Yosemite has been uploaded to

http://downloads.mcstas.org/mcstas-2.1/mac/

The enclosed McStas has a limited set of differences/bugfixes wrt. the official McStas 2.1 released in september, but should generally behave the same.

A few details are pointed out in the README.TXT of the tar.gz archive, listed below.

Best,

Peter Willendrup

Installation README for McStas 2.1 on Mac OS X 10.10 Yosemite
(This is a "respin" of McStas 2.1 done 40 days later than the
 other 2.1 installation packages after Yosemite arrival...)

A) ESSENTIAL PREREQUISITES:
Xcode from Apple, either installed via DVD or from the App Store
Xquartz from http://xquartz.macosforge.org/landing/

B) Run the metapackage for installing the package - the defaults provide the
   essential bits to run McStas with the Perl tools as well as the gcc and
   gfortran compilers from hpc.sourceforge.net<http://hpc.sourceforge.net>, installed to /usr/local.
   Optionally select openmpi for installation, this will also be installed to
   /usr/local.

   NOTE: The included pgplot / mcplot only produces PostSript graphics, sorry!
   This may be remedied in connection with the next McStas release...

   Follow the URL at the end of this document for information on the Python tools

McStas-2.1 is now available in /Applications/McStas-2.1.app - and can be
removed by dragging that bundle to the trash

For installing Python-tools and their dependencies, please follow instructions
at http://www.mcstas.org/download/install_mac_os_x/

Dear all,


As at least one unfortunate McStas user (besides myself ;-) ) has experienced, upgrading to Mac OS X Yosemite 10.10 removes Perl 5.12, which the Perl tools in McStas 2.1 distributed for Maverics rely on...

The only way to get the Perl-tools working again is to recompile both perl-Tk, perl-pgplot, PDL and pgplot… Not a completely trivial exercise, but can be done...

I am in the process of putting together a ‘plug and play' solution, but it may take one or two weeks.


In conclusion: If you need a fully functional McStas, please do not upgrade to Yosemite just yet... :-)

All the best,

Peter Willendrup
