[Pw_forum] Redhat linux PCs ESPRESSO compilation

[Miriam Marques]

  Hello,

  I am trying to compile the ESPRESO package in  Redhat linux PCs
  build system type: i686-pc-linux-gnu, architecture: ia32)

I am using the NagWare f95 compiler (but I have also tried with the  
gfortran compiler).
  When I write ./configure it seems to work
, but it is unable to detect FFTW libraries. In the make.sys the line  
FFT_LIBS is empty as well as the line corresponding to the pgplot  
libraries and MPI_LIBS.

  Writing locate fftw, I can see that the machines have by default  
fftw3, but it
is not recognised by the program. I have tried to indicate where it is  
located,
but it does not work.

  I do not know if I should  install another fftw library. I was  
trying to install a fftw-2.1.5 library (I downloaded it from  
http://www.fftw.org/)
, but I do not know if it is suitable for Redhat linux.
When using it, the line:
FFT_LIBS       = -L/Home/mmarques/fftw-2.1.5/lib -lfftw
appears,
but when executing make all, the error:

make[1]: Entering directory `/phys/linux/mmarques/espresso-3.2/iotk'
cd src ; make libiotk.a
make[2]: Entering directory `/phys/linux/mmarques/espresso-3.2/iotk/src'
cpp -P -traditional -D__FFTW -I../include

iotk_base.f90 -o iotk_base.F90

make[1]: *** [libiotk.a] Error 2
make[1]: Leaving directory `/phys/linux/mmarques/espresso-3.2/iotk'

appears.

On the other hand, when I use FFT_LIBS="/Home/mmarques/fftw-2.1.5/lib"

the line
checking for library containing fftwnd... no
appears.

and the error when executing make all is:

if test -d iotk ; then \
( cd iotk ; if test "make" = "" ; then make  TLDEPS= libiotk.a ; \
else make  TLDEPS= libiotk.a ; fi ) ; fi

Thank you very much for your help,
