Dear Rolly,
The simplest way to tell if the installation went wrong is what you did, check
the output and look for Environ-specific messages. Since there are none, I
would start by double checking that the steps necessary to install Environ went
fine.
These are the steps as reported in the Environ/README file
1) in QE main dir run the script addsonpatch.sh
./install/addsonpatch.sh Environ Environ/src Modules -patch
2) in PW/src dir run
../../Environ/patches/environpatch.sh -patch
3) in install dir run
./makedeps.sh -addson Modules Modules
./makedeps.sh PW/src
4) in QE main dir re-compile pw and neb
make pw
make neb
5) run pw.x with argument pw.x -environ
step 1 should generate some *Environ* files around the QE directories, in
particular there should be a Environ_PATCH file in the main directory, a
make.inc.preEnviron file, an Environ.inc file inside Modules and, most
importantly, there should be some new files inside Modules which are actually
links to the files in Environ/src/. See if you have these files in your QE
directory and check that they are not empty.
step 2 should patch the plugin_*something*.f90 files inside PW/src/, if this
step went fine you should see some extra lines of code within the ***Environ
markers in those files. For example the PW/src/plugin_clean.f90 file after the
patch should look like this

!
subroutine plugin_clean(lflag)
!
! This routine is used for cleaning calls
! from plugins
! DO NOT REMOVE THE TAGS ! ***ADDSON_NAME KIND_OF_PATCH***
!
USE plugin_flags
!
! ***Environ MODULES BEGIN***
!Environ patch
USE environ_init, ONLY : environ_clean
!Environ patch
! ***Environ MODULES END***
!
implicit none
!
LOGICAL, INTENT(IN) :: lflag
!
! ***Environ VARIABLES BEGIN***
! ***Environ VARIABLES END***
!
! ***Environ CALLS BEGIN***
!Environ patch
if(use_environ) CALL environ_clean(lflag)
!Environ patch
! ***Environ CALLS END***
!
end subroutine plugin_clean
If step 3 didn't succeed, the main result would be that you cannot complete
step 4, so I would skip this check.
To double check that the compilation (step 4) went fine, just see if make pw
generated the objects of the new Environ files that were linked in Modules/,
for example check if Modules/environ_main.o or Modules/environ_main.mod are
there.
If all these steps are fine, then there could be a problem with the pw.x
--environ command, but I would not look at that yet. let me know if you manage
to solve the problem or if you have more infos.
Best regards,
Oliviero

Dear Oliviero,
Thank you and I am sorry that I forgot to attach the output file. Here it is
and it definitely missed the Environ subsection. I have also check the result
folder of example01 after calling run_example.sh. Both files missed the Environ
subsection.
I have Intel parallel studio 2015 installed and I have my ./config pointing to
icc ifort mkl etc. I have also followed the Environ installation instructions.
May I know how to check if the installation went wrong?
Thanks,

Subject: Re: [Pw_forum] Running Environ with pw.x
Dear Rolly Ng,
I am not sure about your question, are you concerned that no output specific of
Environ is produced by your calculation? You say this because you confronted
the output you have with the reference reported in the
Environ/example/example01/references directory?
You say that you attached the output, but I can only see the input files, from
which I notice that you are running a calculation in which basically all the
environment effects are turned off (environ_type = vacuum). Still, you should
see some rather minor modifications in the output of pw due to Environ, in
particular a summary of environ input parameters at the beginning (introduced
by "Environ Module”) and a line at each SCF step saying "add environment
contribution to local potential” (while as a matter of fact no contribution is
added if environ_type = vacuum, thus no contribution is reported in the
following output).
If you don’t see any of this things in your output, probably the compilation of
QE + Environ had some problems or you are not using the right executable, since
the input and the command seem ok and Environ 0.2 is fully compatible with QE
5.3.0.
If you want to forward me the output or if you have other doubts or questions,
don’t hesitate to ask the forum or to contact me directly.
Best,
Oliviero Andreussi

Dear Environ users,
I have compile Environ 0.2 with QE v.5.3.0 and I am trying to run example01
using my own input format, so I extract the essential parts from the
run_example.sh as h2o.in and environ.in. These 2 input files are placed in the
same directory.
Then I called mpirun -np 24 ./pw.x --environ -inp h2o.in |tee h2o.out,
I can see the output file is being generated but I cannot see any subsection
stating Environ in the output file as attached.
Did it run with Environ plugin enabled? Is QE v.5.3.0 supported?
Thanks for your advise.
Regards,
Rolly Ng
