can't read "::pwscf::settings(CHDENS)": no such element
Dear users
i am new to pwscf when i try to configure it says success and it recognized all
the lib files and compliers.
but when i give the command make all
it says

configure: success
but make all giving the same error
my system is having ia32, gfortran, fortran77 support, lapack, blas and fftw
waiting for your reply sir

Dear Jibaio Li
Please check your crystallographic parameters carefully. You have used the
lattice parameter value of FCC Ni but followed ibrav = 1 and your atom
positions are also not correct. Delete first 3 atoms and change ibrav =2
and confirm the structure with vesta or xcrysden before carrying
you

/pipermail/users/2022-September/049463.html
you suggest to include la2f = .true for q2r, matdyn.x files as well. After
that we should post process the files to get lambda value without using
lambda.x. Am I right in understanding your message clearly. ??

increase the cut-off till 200 Ry as you suggested but stopped at 90 Ry.
