[Q-e-developers] Compilation problems with xx.f90

[Paolo Giannozzi]

Hi Oliviero

the first error you mention is a line too long (hidden by
preprocessing) and should be fixed (I'll do it). The second, I don't
know, it must be some new feature, I'll inquire with the guys at Nersc
who added it. In general: g95 used to be a great compiler, but it is
unmaintained since 5+ years and slowly fading into obsolescence. I am
strongly against too quick adoption of new language features or new
versions of libraries, but from time to time we have to move on.

First I had a stupid (but never seen before) issue with lines being truncated, in particular when the compiler-time modification of the lines was used, e.g.
