------------------------------------------------------------------------------
Building METIS requires CMake 2.8, found at http://www.cmake.org/, as
well as GNU make. Assumming CMake and GNU make are installed, two
commands should suffice to build metis:
$ make config
$ make
Configuration
-------------
METIS is primarily configured by passing options to make config. For
example:
$ make config shared=1 cc=gcc-4.2
would configure metis to be built as a shared library using GCC 4.2.
Common configuration options are:
cc=[compiler] - The C compiler to use [default is determined by CMake]
shared=1 - Build a shared library instead of a static one
[off by default]
prefix=[PATH] - Set the installation prefix [/usr/local/ by default]
Advanced debugging related options:
gdb=1 - Build with support for GDB [off by default]
debug=1 - Enable debugging support [off by default]
assert=1 - Enable asserts [off by default]
assert2=1 - Enable very expensive asserts [off by default]
METIS' index and real data type size can be configured by editing
include/metis.h.
Installation
------------
To install METIS, run
$ make install
The default installation prefix is /usr/local. To pick an installation
prefix for METIS pass prefix=[path] to make config. For example,
$ make config prefix=~/myroot/
will cause METIS to be installed in ~/myroot/ when make install is run.
Other make commands
-------------------
$ make uninstall
Removes all files installed by 'make install'.
$ make clean
Removes all object files but retains the configuration options.
$ make distclean
Performs clean and completely removes the build directory.
