Hello Samuel,

Sorry for my delayed reply, I was in out of my office.

I am happy that you solved the problem,

I will tried  the same solution for my case also.

Actually, I did already smth for that issue, because my ROOT_v5.26
installation created also problems for the beginning , however I tried below
solution for this

./configure  prefix=/home/data0/root_v5.26  --enable-gsl-shared and it
solves my problems  on 64 bit debian cluster.

However, I will try also your approach to see what will happen.

Best regards,

Sebnem
