[Pw_forum] unable to create directory prefix.save

Dear  Huang Chun Lin,

looking at the error number, which looks like an overflow, it may be that 
your problem is related to a mismatch between the default integer of 
fortran and the type "int" of c...

let me exaplin better:
such error message is given after a call to a c-interface (c_mkdir);
the output of the routine in c is defined as
int retval;
and it is passed to a default integer fortran variable (INTEGER :: ierr) 
in the routine create_directory.

Thus, your problem can be related to the usage of 8byte default integer when 
compiling the fortran code (I met the a similar problem in the past).
To patch it, try to avoid the use of any -i8 flags or, if you have downloaded 
a compiler with i8 default integers, try to force -i4 or similar...

hope it helps
andrea
