Installing ROOT with PYTHIA6 support

[dhashin_krishna]

ROOT Version: 6.30.08
Platform: Ubuntu 22.04.5

Hi Experts,
I am trying to install root with pythia6 support - required to install NuWro. The steps I follow:

mkdir ~/install
cd ~/install

tar xzf pythia6.tar.gz
cd pythia6
sed -i ‘s/g77/gfortran/g’ ./makePythia6.linux
bash ./makePythia6.linux
cd ~/install

tar zxf root_v6.30.08.source.tar.gz
mkdir ~/root
cd ~/root
mkdir ~/root/lib
cp ~/install/pythia6/libPythia6.so ~/root/lib
cmake -DPYTHIA6_LIBRARY=~/root/lib/libPythia6.so -Dpythia6=ON ~/install/root-6.30.08
make -j4

While running the make command, I am getting the following error

CMake Error at /home/name/root/builtins/xrootd/XROOTD-prefix/src/XROOTD-stamp/XROOTD-build-.cmake:49 (message):
Command failed: 2

‘make’

The XROOT build error log file shows:

[I] No git repository info found. Trying to interpret VERSION_INFO
[I] The XrdVersion.hh file already exists

Please let me know what should be done. Thank you!

Hi Dhashin,

Thanks for the post and welcome to the ROOT Community! I am sorry to read ROOT did not work out of the box for you.
It seems that there is a conflict on your system with the libcrypto installed in /user/local.
Have you tried installing the required packages as shown on the website Dependencies - ROOT ?

Cheers,
D

Hi @Danilo , Thanks for your reply

I checked the dependencies. The only error I find is
E: Unable to locate package libvdt-dev

Not sure if this is causing any issue. Other packages are already installed, including the most common optional packages

[Danilo]

Thanks.

libvdt is indeed likely not to be part of the problem.
Can you confirm you installed with apt libssl-dev? The path usr/local looks suspicious for that package manager. Maybe I am wrong, but I think we are dealing with layered incomplete installations done with different package managers on your system: can this be the case?

Cheers,
D

Thank you for your reply @Danilo
I am unsure, but that could probably be the case (incomplete installations). But I am confused about what to remove or if there is a way to fix this. I checked - locate libcrypto and have attached the screenshot for your reference.
