Dear Herve,

Thank you for your explanation.

The reason that xps does not work with ROOT 6 is that I have tried it
but there seem to be so many changes, that I did not succeed.
Since for xps there is no advantage using ROOT 6 vs ROOT 5, and ROOT 5
was still supported, I have decided to stay with ROOT 5.

OK


BTW, I have also one question:
Why did you decide to set up a new Mac with El Capitan instead of using
the newest OS Sierra? (I have the impression that most Mac users are
either happy to stay with their old OS or they upgrade to the newest one.)

Same reason as for the choice of compilers: that's what the R folks
decided to use for producing the Mac binaries of R and CRAN packages.
We're just following their lead on that.

Cheers,
H.


Best regards,
Christian

Hi Christian,

The CRAN folks are currently experimenting with clang 4.0.0 for
producing the Mac binaries of R and CRAN packages so we are using
the same on veracruz2. This is a version of clang that is ahead of
what's in XCode 8.x or XCode 7.x. So I guess that means we'll have
to compile ROOT from source on veracruz2.

BTW any reason not to make xps work with ROOT 6?

Cheers,
H.

Dear Valerie,

I have seen that you have set up a new Mac server, veracruz2, running El
Capitan.

Although the development version of xps does even run on Mac OS Sierra,
one issue still remains the same:

You need to install the latest ROOT version 5, since xps does not run
with ROOT 6!

So you need to install on veracruz2 the same root version that you have
installed on toluca2 running Maverics, i.e.
root_v5.34.36.macosx64-10.11-clang70.dmg

However, if you have installed on El Capitan XCode 8.x instead of XCode
7.x, then you need to compile ROOT from source, i.e.:
https://urldefense.proofpoint.com/v2/url?u=https-3A__root.cern.ch_download_root-5Fv5.34.36.source.tar.gz&d=DwICAg&c=eRAMFD45gAfqt84VtBcfhQ&r=BK7q3XeAvimeWdGbWY_wJYbW0WYiZvSXAJJKaaPhzWA&m=q9mk6yIytaNZlSdiLX_dFwchX8Tb7ra6x3WBBNIcs2o&s=Lz7YkqZ3XwjRsYIXVTbSvbDvTM-jTyoWvoVSa1PdBDw&e=



The README file of xps does explain how to compile ROOT for Sierra. This
should also be valid for El Capitan running XCode 8.x.

Thank you in advance.
Best regards,
Christian
