[Pw_forum] Installation Error

Hi

> ( I followed manual but it gives nothing)

it gives nothing because there is no zhegv in your library

> [root at localhost lib]# nm libfftw.a  | grep T | grep -i fftw_f77
> 00000050 T fftw_f77__

your fftw library contains two underscores at the end.
You need to add one:

CPPFLAGS = -I$(OSHOME)/include/ -DPC -DFFTW  \
           -D"FFTWND_F77_ONE=fftwnd_f77_one_" \
           -D"FFTW3D_F77_CREATE_PLAN=fftw3d_f77_create_plan_" \
           -D"FFTW_F77=fftw_f77_" \
           -D"FFTW_F77_CREATE_PLAN=fftw_f77_create_plan_"

> addusforce.o(.text+0x23eb): undefined reference to `ddot__'

who told you to add one underscore to blas symbols ?
"make clean" before recompiling.

Paolo
