Note for MS-Windows users:

The Makefile for Windows PCs is based on a Makefile written for an earlier version of PWscf (1.2.0), contributed by Lu Fu-Fa, CCIT, Taiwan. You will need the Cygwin package. The provided Makefile assumes that you have the Intel compiler with MKL libraries installed. It is untested.

If you run into trouble, a possibility is to install Linux in dual-boot mode. You need to create a partition for Linux, install it, install a boot loader (LILO, GRUB). The latter step is not needed if you boot from floppy or CD-ROM. In principle one could avoid installation altogether using a distribution like Knoppix that runs directly from CD-ROM, but for serious use disk access is needed.
