[Pw_forum] CPV compilation error

[Eyvaz Isaev]

Hi, 

You need to install FFTW3 library. Presumably, there
is some effort to change from fftw2.1 to fftw3.

As far as I know last releases of SuSe Linux  contain
precomiled fftw3 libraries.
For sources see www.fftw.org, download sources,
compile, and enjoy!

Bests,
Eyvaz.
