Hi,
I want to use PPPM. Now I download FFFW and install it. I use cygwin on
windows xp. How do I add FFFW into Lampps?
Initially, I use make.serial ( which dose not include MPI and FFT), and it
works well without PPPM. I also tried make.cygwin, but it shows errors:
one error is "mpicxx: command not found, Error 127"
and also ask for a lot of files: "filename.d"
My computer only have one processor, so I don't have mpi stuff.
Now how do I change the make file to use PPPM.
thank you very much
guoxin

Guoxin,
If you don't care about running mpi on your cygwin box, you can modify
Makefile.cygwin accordingly, with something like:
CC = g++
CCFLAGS = -O -I../STUBS -I/cygdrive/c/cygwin/fftw/include -DFFT_FFTW
-DMPICH_IGNORE_CXX_SEEK
DEPFLAGS = -M
LINK = g++
LINKFLAGS = -O -L../STUBS -L/cygdrive/c/cygwin/fftw/lib
USRLIB = -lmpi -lfftw
SYSLIB = -lm
SIZE = size
Alternatively, you could start with Makefile.serial and add the FFTW
stuff. You'd probably wind up with just about the same thing.
