root5 libReflex ld -lCore build error

[cdeil (Christoph Deil)]

I updated to macOS sierra and did a fresh install of macports and now this fails:

sudo port install root5

with this build error:

Forgot to say: this is with latest XCode Version 8.0 (8A218a)

Looks like an upstream issue. You should contact them to ask about support for macOS Sierra.

[cjones051073 (Chris Jones)]

But bear in mind root5 is very much depreciated now. You should probably be looking to migrate to root6.

For reference: I've mentioned this issue and ticket in the ROOT forum here:

I see upstream have acknowledged and fixed the issue, pending a release.

Once upstram have released a new version, i will submit a port update.

Please, if this happens and i do not notice, ping this report.

Actually, looking at the commit message it appears adding support for 10.12 removes support for some older OSes (<10.9).

​https://root.cern.ch/gitweb/?p=root.git;a=commit;h=c06fdeae0b3b4d627aacef2bda9df0acd079626b

Its not clear to me whats more important for a legacy package like root5, to support older or newer OSes.

I'll need to run some test once the new tag is out, but if as the above suggests it removes support for older OSes, I am more include to keep root5 on the current version to support the older OSes, and just deprecate support for Sierra, as users of the newer OS should anyway be looking to migrate to root6 in my opinion.

It seems I can keep compatibility with OSX 10.6 upwards using compiler blacklists to force the use of macports clang on OSX <10.8.
