R/Bioc is still building on Mavericks, and before was built on Snow
Leopard (which many people are sill using).
Personally I think that it does not make much difference whether
Mavericks or El Capitan (or Yosemite) is used to build R/Bioc.
However, Sierra is different, and when the CRAN people are experimenting
with clang 4.0.0 for producing the Mac binaries, as Herve has mentioned,
then backwards-compatibility would probably be lost anyhow.
But I understand that this is a decision the CRAN people have to make.
Best regards,
Christian

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.
Also, it's always good not to require users to upgrade if they don't have to.
Building on El Capitan means users will not have to upgrade to macOS Sierra if
they don't want to. Building on Sierra would mean R and packages would not be
backwards-compatible with El Capitan.
But it's a tradeoff that also involves the difficulty of maintaining build
machines with old OSes, and wanting to take advantage of newer compiler
technology. Otherwise R/Bioc would still be building on Mavericks, or Snow
Leopard...

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
