[Pw_forum] installation problem

[Prasenjit Ghosh]

Dear All,

I tried to install PWscf v.2.0.4 with GUI, on a linux pc using intel
compiler. the following is the message I'm getting while installing using
the ./configure command:

-----------------------------------------------------------------
PWscf can take advantage of several optimized numerical libraries
(essl, fftw, mkl...). This configure script attempts to find them,
but may fail if they have been installed in non-standard locations.

The following libraries have been found:
  LIBS= -llapack -lblas

If any libraries are missing, you may specify a list of directories
to search and retry, as follows:
  ./configure LIBDIRS="list of directories, separated by spaces"

For more information, read the INSTALL file or the PWscf manuals.

Can any one of you throw any light on it. To me it appears that it can't
recognize the ifc compiler. but i don't know how to fix it.


Thanks in advance.
