Now, running QE 4.2.1 example 12 under an Ubuntu 8.04.4 umbrella goes just fine. So...I smell a fortran compiler problem here. 8.04.4 comes with gfortran-4.2, whilst 10.04.1 has “upgraded” to gfortran-4.4. Anyone else run into gfortran problems with QE 4.2.1?

I’ve heard both good and bad things about gfortran, but there does seem to be some agreement that it produces reasonably optimized code. And it’s free...cheap at twice the price.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Paul Grant<o:p></o:p></p><p class=MsoNormal><a href="http://www.w2agz.com">www.w2agz.com</a><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
