How to install ROOT with cling

[mattiad]

Hi,
I’m using ROOT from years but I’m not an expert in compile it. I’m really looking foward of the first official release of cling.

So I would like try the test version but I can not compile root with that.

I tryed with to extract ecsft.cern.ch/dist/cling/curren … 88.tar.bz2
in my home folder and then I tryed to compile ROOT with the command

./configure --build=debug --with-llvm-config=/home/myhome/cling-Ubuntu-12.04-64bit-r45688/bin --enable-cling make

The result is an error.

Any advance?

The result is:

…

Hi,

The build problem should be fixed now; you’re welcome to try tomorrow’s nightly snapshot! We do have a major issue at runtime, though (the dictionary replacements don’t load correctly). This is really work in progress, lots of changes every day… Your chances that ROOT + cling work might be better next week

Thanks for trying and for your report! We’re also looking forward to ROOT 6!

Cheers, Axel.
