[Pw_forum] compilation error

[Bhagawan Sahu]

Paolo,

thanx. It could get past that. Now it gives errors in 'include' files of 
fftw. I used the machine installed fftw. The version is 2.1.5. 

In the make.sys,

DFLAGS         =  -D__LINUX -D__INTEL -D__FFTW -D__MPI -D__PARA
FDFLAGS        = $(DFLAGS)
IFLAGS         = -I../opt/apps/fftw/fftw-2.1.5/include -I../include

I have loaded the fftw-related environment variables. but it gives the 
error:

make[1]: Entering directory `/home/utexas/ee/eefz340/espresso-3.1/clib'
icc -O3 -D__LINUX -D__INTEL -D__FFTW -D__MPI -D__PARA 
-I../opt/apps/fftw/fftw-2.1.5/include -I../include  -c fft_stick.c
fft_stick.c(19): catastrophic error: could not open source file "fftw.h"
  #    include <fftw.h>
                       ^
 
compilation aborted for fft_stick.c (code 4)
make[1]: *** [fft_stick.o] Error 4
make[1]: Leaving directory `/home/utexas/ee/eefz340/espresso-3.1/clib'
make: *** [libs] Error 2

It is not able to find fftw.h from /opt/apps/fftw/fftw-2.1.5/include

I checked this path. fftw.h exist and not empty. Also in the clib 
directory of espresso-3.1, fftw.h exists.

We also have fftw version 3.1.1. It's include file is fftw2.h. In order to 
include this .h file, which files in clib or other directories need to be 
changed so that it can identify fftw3.h instead of fftw.h
