[Pw_forum] QE 4.0.2: configure error

[Sangamesh B]

Hi all,

     I tested the installation of Quantum Espresso-4.0.2 on Rocks-5.0 with
GNU compilers ( gcc-4.1.2 & gfortran-4.1.2) succeessfully.

But the same installation is failing on Rocks-4.2 cluster either with GNU
compilers or pathscale compilers.
The error is:

configure:2314: WARNING: serial/parallel compiler mismatch detected
configure:2316: WARNING: parallel compiler  uses gfortran, but serial
compiler is /usr/bin/gfortran
...
configure:2983: /usr/bin/gcc4 -E  conftest.c
conftest.c:9:28: error: ac_nonexistent.h: No such file or directory
configure:2989: $? = 1

configure:4172:  --version </dev/null >&5
./configure: line 4173: --version: command not found

./configure: line 4178: -v: command not found
configure:4180: $? = 127
configure:4182:  -V </dev/null >&5
./configure: line 4183: -V: command not found
configure:4185: $? = 127
configure:4193: checking whether we are using the GNU Fortran 77 compiler
configure:4207:  -c  conftest.F >&5
./configure: line 4208: -c: command not found
configure:4213: $? = 127
....

The GNU version of Rocks 4.2 is 4.1.0 but in Rocks 5.0 it is 4.1.2.

The strange thing happened with Rocks-4.2 is, if the variables CC, F77 or
MPIF90 did not set to either gcc or pathscale, then configure works fine,
but fails during make.

If set the variables it fails in configure itself.

I'm attaching here the config.log file.

Please let me know if any one has faced this problem or atleast anybody
successful to install QE on Rocks 4.2.

Thanks,
Sangamesh
