root6: error: thread-local storage is unsupported for the current target

What variants are you using (not so easy to decipher from the log...).

port installed root6

Can you try an uninstall followed by clean install, rather than an upgrade ?

sudo port uninstall root6
sudo port install root6 +<whatever variants you want>

Is your Xcode and command lines tools up to date ?

I have

MacBookPro ~/Downloads > /usr/bin/clang -v
Apple LLVM version 6.0 (clang-600.0.51) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin13.4.0
Thread model: posix

whereas your log says

:info:configure -- The C compiler identification is AppleClang 5.0.0.5000279
:info:configure -- The CXX compiler identification is AppleClang 5.0.0.5000279

Please make sure you are using the latest versions compatible with OSX10.9, and then try again.

I think the issue of thread-local storage came up in #44062 previously, although I would have thought that the version of clang being used here would work based on that...

Hi,

The error message here is the same as in the OSX 10.6 log file in #45265, that ultimately lead to that OS no longer being supported by the root6 port.

I still suspect the OP's Xcode and/or command line tools are not the latest, which is required to support root6. Updating is I think the solution. Failing that, if they are not willing, then try with the +clang34 variant, that then forces the use of macPorts Clang 3.4 compiler. This is the compiler used on OSX 10.7 and 10.8, for the very reason that the default compilers there are also not up to date enough to support compiling root6.

I did an uninstall, upgraded my Xcode to 5.1.1 and tried again, and doing one or both of those allowed it to install cleanly. Thanks guys.

Thanks for the feedback. Useful to know root6 did not support the older Xcode...

I have been trying to compile against the root libraries provided through macports and keep running into a similar error posted in this following URL.

​https://root.cern.ch/phpBB3/viewtopic.php?t=19551&p=83737

The root developers say they've fixed the problem and that it is now compatible with OS X 10.10.3 Xcode 6.3.2 and this is correct. If I re-compile the root v6-04-00 natively on my machine, I don't have an issue compiling against the headers. I was wondering what version of Xcode/clang this current port was compiled with and if it could be recompiled to bring it up-to-date. That is if it'll actually fix the problem. May just be a problem on my end.

This report was about ROOT 6.02.00. Based on the reply and the link on the forum I guess this has been solved with new version of ROOT? (We are at version 6.06.00 now.)

In case this is still a problem, please reopen the ticket or open a new one.
