Hi,

I am very new.

I am trying to install open-coarrays-bin on my BRAND SPANKING NEW Ubuntu 20.04 Ubuntu Focal Fossa (development branch).

I did

sudo apt update
sudo apt upgrade

However, when I execute

sudo apt install open-coarrays-bin

I am getting the following error:

E: Unable to locate package open-coarrays-bin

computertu@computertu:~/Desktop$ sudo apt install gfortran libcoarrays-dev libopenmpi-dev open-coarrays-bin
[sudo] password for computertu: 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package open-coarrays-bin
computertu@computertu:~/Desktop$

I was following the article from last year:

Fortran 2018 coarray quick start
24 April, 2019

https://www.scivision.dev/fortran-2018-coarray-quick-start/

So ..., what is the way (or easiest/best/most_flexible/awesome way) to install? Is there some better URL/method to follow?

I do prefer the cutting edge.

I noticed mentioned EasyBuild and Spackon the page https://github.com/sourceryinstitute/OpenCoarrays/blob/master/INSTALL.md

Are either good methods?

What are the general recommendations?

Thank you, Andre Mikulec Andre_Mikulec@Hotmail.com

All,

I tried SEVERAL THINGS (but not everything).
This is the way I could get opencoarrays 2.8.0 compiled and built (and working, so far) on Ubuntu Focal Fossa (development branch) 20.04.

This is from a perfectly new Ubuntu Focal Fossa (development branch) 20.04
