[Pw_forum] Quantum Espresso installed, but examples not running

[Alexander Eftimiades]

If I uninstall FFTW from synaptic then synaptic will uninstall quite a  
few other packages. What about:
Paolo Giannozzi's suggestion--
If this message appears for all errors, compile internal
FFTW instead of using external FFTW v.3: in make.sys
replace -D__FFTW3 with -D__FFTW and remove -lfftw3
from libraries, delete all objects that depend upon such
options (rm Modules/fft_scalar.o clib/fft_stick.o should
be enough),  recompile

I still do not know what you mean by "internal"? Do you mean Quantum  
Espresso comes with FFTW? Do I have to download/install anything or do  
I just set these variables in the make.sys file and compile as usual?
