Root5 fails at run time

[unelg (gokhan unel)]

Root Version 5.34/37 compiles on High Sierra, but running fails with:

dlopen error: dlopen(/opt/local/libexec/root5/lib/root/libThread.so, 9): can't resolve symbol __DefaultRuneLocale in /opt/local/libexec/root5/lib/root/libThread.so because dependent dylib #1 could not be loaded in /opt/local/libexec/root5/lib/root/libThread.so

(same errors on a fresh compilation downloaded from sources)

In the future, please use WikiFormatting, fill in the Port field and Cc the port maintainers (port info --maintainers nco), if any.

ROOT5 has not been updated for some time, and likely never will for maxOS 10.13. I'll take a look sometime to see if anything can be done but I recommend you look to migrating to ROOT6 instead.

I am able to reproduce the issue.

Some basic attempts to fix it, such as updating to the latest git revision in the 5.34 branch, or using macports clang (3.8 or 3.9) did not help (root5 did not even compile with the later).

I am afraid there is nothing much more I can do here, as this is an issue for upstream to address. I will leave it to you to follow up with upstream if you wish to see if they are interested in fixing this. If they are I will happily use any future updates. I will not though look into fixing it myself.

Finally, I repeat, in the long run you will be much better served looking to migrate to ROOT6.

I have decided to officially retire support for ROOT5 starting with mac OS 10.13. ROOT5 is very much depreciated, and it was just a matter of time before it would no longer work. It was always my intention to do this eventually, and now seems as good a time as any.

Why make that that keyword change ? Both work just the same...
