[Pw_forum] Making Changes in pw.x

[Paul M. Grant]

Thanks, Prasenjit.

 

I do have the make.sys file.but how does make "know" what's been changed.is
there a database of original electron.f90 creation dates somewhere?  I
confess I'm not exactly an expert on the linker process in linux.for OS/360
I once was!  Is there an online manual on fortran and linking resultant .o
and the (mysterious to me) .mod files?

 

Thanks again.

 

-Paul

if you have the make.sys file, then make all or make pw will be sufficient.
The subroutines which have been changed will be recompiled, linked and the
pw.x will be created.

I know I've done this before, but can't remember how.  Suppose I want to
make a small change in one of the routines used by pw.x, let's say
electrons.f90.  What do I do after making and saving the changes?  Do a
fortran compile and then make all?
