Hi Elie
The executable generated in my computer will be useless to you,
because these days most if not all libraries linked to an executable are
dynamic/shared libraries.
You won't have the same in your computer, or the equivalent will be
located in different places, may be from different versions, etc.
(E.g. your Intel compiler libraries will be from a different version,
in a different location, and likewise for OpenMPI libraries etc.)
Take any executable that you may have in your computer and do "ldd
exectuable_name" to see the list of shared libraries.
The error you reported suggests a misconfiguration of Makefiles,
or better, a mispositioning of directories.
**
First thing I would try is to start fresh.
Delete or move the old directory trees,
download everything again on blank directories,
and do the recipe all over again.
Leftovers of previous compilations are often a hurdle,
so you do yourself a favor by starting over from scratch.
**
Second *really important* item to check:
The top directories of QE and EPW *must* follow this hierarchy:
espresso-4.0.3
|-- EPW-3.0.0
Is this what you have?
The EPW web site just hints this in their recipe step 3.
The Makefiles will NOT work if this directory hierarchy is incorrect.
The error you reported in your first email *suggests* that the Makefiles
in the EPW tarball are not finding the Makefiles in the QE tarball,
which indicates that the the directories may not have a correct relative
location.
I.e. the EPW top directory must be right under the QE top directory.
**
Third thing, is that you have to follow the recipe strictly (and on
the EPW web site there seems to be typos and omissions):
1) untar the QE tarball:
tar -zxf espresso-4.0.3.tar.gz
2) move the EPW tarball to the QE top directory produced by step 1
above, something like this:
mv EPW-3.0.0.tar.gz espresso-4.0.3
3) untar the EPW tarball you copied/moved in step 2 above,
something like this:
cd espresso-4.0.3
tar -zxf EPW-3.0.0.tar.gz
4) Set up your OpenMPI environment (assuming you are using OpenMPI
and that it is not installed in a standard location such as /usr/local):
[bash/sh]
export PATH=/your/openmpi/bin:$PATH
export LD_LIBRARY_PATH=/your/openmpi/lib:$LD_LIBRARY_PATH
[tcsh/csh]
setenv PATH /your/openmpi/bin:$PATH
setenv LD_LIBRARY_PATH /your/openmpi/lib:$LD_LIBRARY_PATH
5) configure espresso-4.0.3, i.e, assuming you already are in the
espresso-4.0.3, do:
./configure CC=icc F77=ifort
(assuming you are using Intel compilers, and that you compiled OpenMPI
with them, if you did
not, say, if you used gcc and gfortran, use CC=gcc FC=gfortran instead)
6) Run "make" on the top EPW directory:
cd EPW-3.0.0
make
When you configure QE it doesn't compile anything.
It just generates/sets up a bunch of Makefiles in the QE directory tree.
When you do "make" on the EPW-3.0.0 directory the top Makefile just
says (cd src; make).
If you look into the "src" subdirectory you will see that the Makefile
therein points to library and include directories two levels above,
which means that they are in the *QE* directory tree:
*********
IFLAGS = -I../../include
MODFLAGS = -I./ -I../../Modules -I../../iotk/src \
-I../../PW -I../../PH -I../../PP
LIBOBJS = ../../flib/ptools.a ../../flib/flib.a \
../../clib/clib.a ../../iotk/src/libiotk.a
W90LIB = ../../W90/libwannier.a
**********
Hence, if your QE directory is not immediately above your EPW directory
everything will fail, because the EPW Makefile won't be able to find
the bits and parts of QE that it needs.
And this is *exactly what the error message in your first email showed*,
a bunch of object files that were not found.
***
Sorry, but I cannot do any better than this.
I hope this helps,
Gus Correa

Ray and Gus,
Thanks a lot for your help. I followed Gus' steps. I still have the same
problem for the compilation (I didnt check the libraries part though!).
The executables for quantum espresso work pretty fine. I have got them
in espresso-4.0.3/bin:
dynmat.x iotk iotk_print_kinds.x iotk.x matdyn.x ph.x pw.x q2r.x.
The problem are the EPW executables and I dont understand why.
Gus do me a favor: can u send me all the EPW executables that you have
produced, in the epw.x? I guess this resolves the problem for the moment.
Regards
ELIO
