Quantum espresso installation problem

Click For Summary
SUMMARY

The installation issue with Quantum Espresso 6.1 arises during the compilation phase, specifically when executing the "make all" command. The error message indicates a problem with a pointer dummy argument in the Fortran source file realus.f90, where an INTENT(IN) argument is incorrectly used as an actual argument for a subroutine expecting INTENT(OUT) or INTENT(INOUT). To resolve this, users should seek assistance from the Quantum Espresso mailing list for expert guidance on correcting the variable assignment error.

PREREQUISITES
  • Familiarity with Fortran programming language
  • Understanding of Quantum Espresso software and its installation process
  • Basic knowledge of compiling software from source code
  • Experience with error debugging in Fortran applications
NEXT STEPS
  • Consult the Quantum Espresso mailing list for specific installation issues
  • Review Fortran documentation on pointer dummy arguments and their attributes
  • Investigate common compilation errors in Quantum Espresso 6.1
  • Explore best practices for variable assignments in Fortran programming
USEFUL FOR

This discussion is beneficial for researchers, developers, and computational scientists working with Quantum Espresso, particularly those involved in installation and troubleshooting of Fortran-based applications.

Hi,
I am trying to install quantum quantum espresso 6.1 in our cluster. I can do the ./configure successfully. But after that when I try to do "make all" I am getting the following error:
fortcom: Error: realus.f90, line 377: A pointer dummy argument with the INTENT(IN) attribute shall not appear as an actual argumen t if the associated dummy argument has the INTENT(OUT) or INTENT(INOUT) attribute. [TABP]
CALL real_space_q( nt, ia, mbia, tabp )
------------------------------------------^
compilation aborted for realus.f90 (code 1)
make[2]: *** [realus.o] Error 1
make[2]: Leaving directory `/home/nanoSIUC/myruns/zunaid/qespresso6.1/qe-6.1/PW/src'
make[1]: *** [pw] Error 1
make[1]: Leaving directory `/home/nanoSIUC/myruns/zunaid/qespresso6.1/qe-6.1/PW'
make: *** [pw] Error 1

Can anyone help me to solve this problem of installation.
Thank You

It looks like there's a bad variable assignment of some kind. You should probably start by asking this question on the quantum espresso mailing list. They'll be best positioned to give you guidance.

I am having a hell of a time finding a good all-in-one inkjet printer. I must have gone through 5 Canon, 2 HP, one Brother, one Epson and two 4 X 6 photo printers in the last 7 yrs. all have all sort of problems.

Mainly it's for my wife which is not exactly good in tech. most of the problem is the printers kept changing the way it operate. Must be from auto update. I cannot turn off the...
