[QE-users] Failure in installing QE 6.7 in a server

[Pietro Davide Delugas]

hello

when you compile the qe, first the program creates all executables in 
bin subdirectory of the top qe directory. Check if they are there.

If they are:  you may either avoid the secod step either using  the full 
path to execute the program.

e.g. in my case

/home/pietro/q-e/bin/pw.x

or adding  to the q-e/bin directory to the default path. For example in 
my case:

type the bash command

export PATH=/home/pietro/q-e/bin:$PATH

The second installationt would be copying the executables in a specified 
directory, that, if I am not wrong,  by default is /usr/local/bin  for 
which you would need the administrator privileges.


The second thing you tried has nothing to do with the compilation of the 
package.

It's ubuntu that knows that there is a debian package of 
quantum-espresso available, and asks you if you want to install it. But 
again to do this you need administrator privileges.


hope it helps

best regards -- Pietro
