Have a problem using ACLIC of v6.08.00

Hello,

I have downloaded into my MacBook Air the binary file root_v6.08.00.macosx64-10.12.tar.gz
from root.cern.ch/content/release-60800
I have decompressed it in my directory Downloads using the command
tar -xzvf root_v6.08.00.macosx64-10.12.tar.gz
It gave me a directory /Users/elemernagy/Downloads/root
I put a line in my .login file:
source Downloads/root/bin/thisroot.sh
I have issued a command
source .login
and started to execute root in a directory
/Users/elemernagy/work/bridge
root -x CardDa,C
worked fine.
However when trying ACLIC in a root session it ended with the following error:
elemers-macbook-air:bridge elemernagy$ root

I would appreciate somebody tells me what did I wrong.

PS BTW the above procedure worked fine w/o error with an old version:
root_v5.34.18.macosx64-10.9-i386.tar.gz
so I suspect that something has changed since this version, and especially in v6.08/00.

Did you install latest Xcode and the command line tools?

If you mean by Xcode X11, yes, I have the latest one.
On the other hand I don’t know what you mean by Command Line Tools.

To install the command line tools you need to run ‘xcode-select --install’ from a terminal.
See root.cern.ch/build-prerequisites#macosx

Many thanks for this good suggestion, now also ACLIC works w/ v6.08/00.
Best, Elemer
