EPW Forum

Hi everyone,

I just study the EPW from the school2018 document. In the exercise 2 in Tuesday, it is said that in order to calculate the semiconductor, the ph.x should be re-complied.

After : cp do_phonon.f90 elphon.f90 phq_readin.f90 symdyn_munu.f90 PATH/q-e/PHonon/PH
I can't recompile successfully, with the following errors:

elphon.f90(282): error #7002: Error in opening the compiled module file. Check INCLUDE paths. [WAVEFUNCTIONS_MODULE]
USE wavefunctions_module, ONLY: evc
------^
elphon.f90(293): error #6580: Name in only-list does not exist or is not accessible. [LRWFC]
USE units_ph, ONLY : iubar, lrbar, lrwfc, iuwfc
-------------------------------------^
elphon.f90(293): error #6580: Name in only-list does not exist or is not accessible. [IUWFC]
USE units_ph, ONLY : iubar, lrbar, lrwfc, iuwfc

elphon.f90(367): error #6404: This name does not have a type, and must have an explicit type. [EVC]
CALL get_buffer(evc, lrwfc, iuwfc, ikk)


Does anyone saw this before? Thank you so much!

Hi shashali,

Are you using the same version of qe that was used during the school? I think in the school qe-v6.2.2 was used.

Hi, Hari Paudyal

Thank you so much for your attention. I used the qe6.4.1. I will try the 6.2.2. Thank you!

Dear shasha,

If you want an up-to-date version of the files, you can also look into q-e/test-suite/not_epw_comp
