These are some preliminary instructions for the 5.0 release of METIS.

1. You need to have a C compiler that supports the C99 standard. 
   Gcc works just fine, but I have not tested it on many other architectures
   (any feedback/patches for different architectures are welcomed)
   
2. You need to have GNU make and CMake 2.8 (https://www.cmake.org/) installed.

3. Edit the file include/metis.h and specify the width (32 or 64 bits) of the
   elementary data type used in METIS. This is controled by the IDXTYPEWIDTH
   constant.

   For now, on a 32 bit architecture you can only specify a width of 32, 
   whereas for a 64 bit architecture you can specify a width of either 
   32 or 64 bits.


4. At the top of Metis' directory execute 'make' and follow the instructions.
   
      make distclean
      make config cc=icc      (specify cc name)
      make

      The binaries are in build/<arch>/:
      1) Stand-alone bin: programs/
      2) API: libmetis/

5. To build on windows using Visual Studio follow the instructions in the
   file BUILD-Windows.txt.
