REST install with preexisting root

[bencattermole]

Preexisiting root install

if you have source thisRoot.sh in your .bashrc this will take priority over your conda environment, to successfully launch root from the conda env you need to remove this from your path (echo $PATH)

Creating environment - troubleshooting

• Connection broken: incomplete read( ... )

After trying to create conda environment with Geant4, this error is caused by losing internet connection during install. Simply try again with a better connection

Testing environment

to test your newly created environment run:

root

you should get:

[text welcoming you to root, your root version, operating system version
root[0]

if you get

error: unable to read PCH file /home/ben/anaconda3/envs/RestG4/etc//allDict.cxx.pch: 'No such file or directory'
fatal error: PCH file '/home/ben/anaconda3/envs/RestG4/etc//allDict.cxx.pch' not found: module file not found
*** Break *** segmentation violation

then you are have another install of root in your PATH variable

Installing REST-for-physics

cd ~/
mkdir REST-for-physics
cd REST-for-physics
mkdir rest-framework
cd rest-framework
git clone https://github.com/rest-for-physics/framework.git .
python pull-submodules.py –latest:master

should be changed to

cd ~/
mkdir REST-for-physics
cd REST-for-physics
mkdir rest-framework
cd rest-framework
git clone https://github.com/rest-for-physics/framework.git .
git checkout 9bfed7c
python pull-submodules.py –latest:master

This is the correct version of REST from December 22.

Trouble shooting

after make install if you get :

error: unknown type name 'any'

or

-lstdc++fs: not found

You are trying to install the wrong version of REST for your ROOT and Geant4 versions, you need to go back and change the version of REST you git cloned.
