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

[Ari P Seitsonen]

Dear Oliviero, CC: All Others

   My guess: It is a feature either in newer standards of FORTRAN, or 'g95' 
has not implemented it. Sorry, I am too busy (lazy) to check it myself, 
one could try restricting the 'gfortran' to a specific standard. What I 
can possibly contribute is that this kind of errors appeared some years 
ago in CP2K, a code that has a long history of testing the FORTRAN 
compilers, and I seem to remember that the Developers decided to abandon 
g95, but it could be also that this was because they went for a standard 
"higher" than the official FORTRAN90.

   If no one has better answers, I can try to check later, just giving my 
first "experience" right now.

     Greetings from Paris,

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.
