<pre>Dear Quantum Espresso Users
I had installed Quantum Espresso previously on my AMD (3 core)
parallel. but Now I get an error !!
I have installed Intel Compilers (version 11) included fort, icc,
icpc, and Math Kernel; and parallelized them by lam successfully.
my operating system is OpenSUSE 11.2 (64 bit). Also mpif77 and
mpicc work well on my 3 core AMD.
I have installed ACML also, that is not necessary when we have MKL.
but error: Fortran 77 compiler cannot create executables !!
linux-4koa:~/Install/QSPRESSO4.1.2/espresso-4.1.2 # ./configure
MPIF90=mpif77 F77=mpif77 CC=mpicc --enable-parallel
checking build system type... x86_64-unknown-linux-gnu
checking architecture... x86_64
checking for ifort... ifort
checking for Fortran 77 compiler default output file name...
configure: error: Fortran 77 compiler cannot create executables
See `config.log' for more details.
with and without --enable-parallel I saw the same error. anyhow it is
amazing that I had installed parallel Quantum Espresso on this AMD and
using
CentOS5.4 (64 bit) as the Operating system.
This is Ngoc Linh Nguyen's solution :
The problem could come from Fortran 77 compiler.
You say that the Intel Compilers (version 11) included ifort, icc ...
has been installed, so let try compiling without specifying "F77=mpif77
CC=mpicc".
but this can not help me, and the error remained.
<br>Someone here suggested me below lines but the error remained:
<br>linux-76gb:~/LinSoft/QSPRESSO4.1.2/espresso-4.1.2 # ./configure MPIF90=mpif77 F77=ifort CC=icc –enable-parallel
checking build system type... x86_64-unknown-linux-gnu
checking architecture... x86_64
checking for ifort... ifort
checking for Fortran 77 compiler default output file name... configure: error: Fortran 77 compiler cannot create executables
See `config.log' for more details.
<br><br>Is it really necessary to install a F77 compiler?
I think that the ifort is sufficient !! No ?!!
<br>I appreciate so much if you help me. Many thanks
