Unresolved while linking [cling interface function]!

I can’t execute a macro with TBrowser or .x command

IncrementalExecutor::executeFunction: symbol ‘_ZN5cling10printValueEP7TObject’ unresolved while linking [cling interface function]!
You are probably missing the definition of cling::printValue(TObject*)
Maybe you need to load the corresponding shared library?
(TBrowser &) Error in ValuePrinter: missing output string.

I guess you compiled ROOT 6 with gcc 5.x.
If this is the case, see the beginning of: ROOT v6-06-04 on Ubuntu 16.04


Note that the HEAD of ROOT’s master should have this fixed.
