<div dir="ltr">Hi all,<br><br> 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.<br><br>But the same installation is failing on Rocks-4.2 cluster either with GNU compilers or pathscale compilers.<br>
The error is:<br><br>configure:2314: WARNING: serial/parallel compiler mismatch detected<br>configure:2316: WARNING: parallel compiler uses gfortran, but serial compiler is /usr/bin/gfortran<br>...<br>configure:2983: /usr/bin/gcc4 -E conftest.c<br>

....<br><br>The GNU version of Rocks 4.2 is 4.1.0 but in Rocks 5.0 it is <a href="http://4.1.2./" target="_blank">4.1.2.</a><br><br>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.<br>
<br>If set the variables it fails in configure itself.<br><br>I'm attaching here the config.log file.<br><br>Please let me know if any one has faced this problem or atleast anybody successful to install QE on Rocks 4.2.<br>
<br>Thanks,<br>Sangamesh</div>
