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
