[CP2K-user] [CP2K:18204] ELPA configure error: No usable BLACS found

[Trevor Voss]

Hello everyone, 

First thing to note is that I am a total noob at all of this. This is my 
first time using Linux (luckily I have an expert to help me).

I am working to build CP2K on Ubuntu 22.04.1 LTS with an AMD Threadripper 
3970x and NVIDIA 3090Ti using MPI support with openmp. 

I am getting the following error with the configure step in the 
installation of ELPA: "No usable BLACS found. If installed in a 
non-standard place, please specify suitable LDFLAGS and FCFLAGS as 
arguments to configure."

I have added the BLACS installation location to my $PATH and 
$LD_LIBRARY_PATH, and tried using the LD and FC flags, but I cannot for the 
life of me figure out the proper syntax to get it to find my BLACS install. 

Has anyone encountered this error or have any insight for how to include 
the BLACS installation path for ELPA? Please and thank you!
