Error in piloting DOS

[Sherif_Yehia1]

Dear Users and experts

I am new users in vasp and need your help
Please see following I am trying to Use py4vasp to plot the DOS as written in the tutorial part2 and keep getting the following error
Any advisable comments would appreciated
Thank you

Please also check whether you are running the Python script in the same directory or pass the appropriate filename including the path.

Hello!

I think you are missing the HDF5 output file which VASP generates when you compile it with -DVASP_HDF5 (see blue info box here). Although there are output files in your example folder, I do not see the .h5 files which are read by py4vasp.

Please try recompiling VASP with HDF5 support and try to run the example again!

Best,
Andreas Singraber

Thank you very much

May be I am doing something wrong but I just send another inquires

because when I put CPP_OPTIONS on i.e.

# HDF5-support (optional but strongly recommended)
CPP_OPTIONS += -DVASP_HDF5
HDF5_ROOT ?= /usr/local/hdf5
LLIBS += -L$(HDF5_ROOT)/lib -lhdf5_fortran -lhdf5
INCS += -I$(HDF5_ROOT)/include

I am keep getting the following error I am using

vhdf5_base.o: In function `vhdf5_base_mp_vh5_start_':
vhdf5_base.f90:(.text+0x46): undefined reference to `h5lib_mp_h5open_f_'

My hdf5 is hdf5-1.13.3 system Centos8 Intel FORTRAN compiler

Please see part my makefile.include the rest NO change

VASP_TARGET_CPU ?= -march=core-avx2
FFLAGS += $(VASP_TARGET_CPU)

Thank for your effort and time
