[Pw_forum] Compile pwscf on HP Unix

[Yu Xie]

Dear PWSCF users,

I'm trying to install the pwscf 3.2.3 on a HP Unix machine. The  
compiler is f90. And I got some problems with compute_fes_grads.F90.  
The error message is like below:

         cpp -P -traditional -D__FFTW -D__USE_INTERNAL_FFTW -D__MPI -

2 Errors
f90: error 213: Errors detected.

Stop.

How can I correct this error?

Thanks very much!

With mu best regards,
