Missing gfortran - CentOS 8

Installation
1

Hello David,

Thanks always for your feedback …
I did install Pillow as a user , i.e. pip3 install Pillow --user.
But the “chck_luka.py” produce a Warning and Error!
…Error:
{flukadir}/bin/lfluka -o testfluka doesn’t compile/link properly <<<<<

	**Please ensure you have the correct version of fluka with the appropriate compiler**

I installed Fluka from “fluka-4-1.1.Linux-gfor9.x86_64.rpm”.

Thanks

Dear Arthur,

this time the issue is that the script can’t find the gfortran compiler on your system.

for the FLUKA package you installed, you will need gfortran 9. To install this you need the following commands:

sudo yum install centos-release-scl
sudo yum install devtoolset-9

Then you need to activate it with

scl enable devtoolset-9 bash

This command can be added to your .bashrc to run it every time you log in.

Cheers,
David

Thanks David,

Yes, my gfortan was the problem …
Some reason it was my oversight. I installed “gcc-gfortran” and with that … all the test for the python script passed …
