[Pw_forum] FFTW problem

[sprokuda at dnk.ru]

Dear Paolo!

I've reported you aobut my problem with #define FFTW, I had following
compilation error:

> ifc -Vaxlib -O2 -tpp6 -fpp -I/home/sprokuda/PWscf/include/ -D__LINUX

you replied :

which version of the code are you using ? the one on the web, the one or 
cvs,...? C_POINTER is defined in include/machine.h

I've modified machine.h as following :

!#if defined(CRAYY) || defined(SGI) || defined(PC) || defined(AIX) || !defined(T3D) //||defined(HITACHI) || defined(SUN)
#define C_POINTER  integer
!#endif

it seems my Linux doesn't understoond "PC", and now I have following
after issuing "make pw" :

I was looking for routines and files with name fftw_f77_*, but I've
found nothing (except fftw.f90 in Modules, but there is nothing
relevant). what could be the reason for those errors ?

Best wishes, Sergey Prokudaylo.
