Building and Installing
=======================

For the impatient:

  $ ./configure
  $ make
  $ make check
  $ make install

Alternatively (and recommended), use a remote build directory:

  $ mkdir build
  $ cd build
  $ ../configure
  $ make
  $ make check
  $ make install

If you can't seem to find configure then you probably downloaded the
source, you'll need to "bootstrap" your development environment with:

  $ ./bootstrap

There are numerous configuration options that might be applicable to
you. Check them out via:

  $ ./configure --help

The specific options that might be relevant include:

  --disable-java          don't build Java bindings
  --disable-python        don't build Python bindings
  --disable-webui         don't build webui (requires Python 2.6)
  --disable-optimize      don't try to compile with optimizations
  --without-included-zookeeper
                          excludes building and using the included ZooKeeper
                          package in lieu of a system installed version (note,
                          however, that no attempt is made to find the package
                          and explicitly setting CPPFLAGS and LDFLAGS as
                          appropriate may be necessary)

And the specific environment variables that might be relevant are:

  JAVA_HOME   location of Java Development Kit (JDK)
  JAVA_CPPFLAGS
              preprocessor flags for JDK
  JAVA_LDFLAGS
              linker flags for JDK
  PYTHON      which Python interpreter to use

We've tailored a few scripts with the configure options and
environment variables necessary for different environments:

  ./configure.amazon-linux-64
  ./configure.centos-5.4-64
  ./configure.macosx
  ./configure.ubuntu-hardy-64
  ./configure.ubuntu-karmic-64
  ./configure.ubuntu-lucid-64
  ./configure.ubuntu-natty-64


Java
====

During configuraiton we attempt to determine a suitable location for
JDK so that we can build JNI based libraries. If we can not do so, you
may need to try setting JAVA_HOME, JAVA_CPPFLAGS, or JAVA_LDFLAGS
manually.

The resulting libmesos.a/so/dylib will include the Java bindings (JNI)
if they are enabled (which they are by default, and can be disabled
with the '--disable-java' configuration option). The Mesos JAR can be
found in [build]/src (where [build] represents a remote build
directory if any).


Python
======

We build a Python egg that can be included in the PYTHONPATH when
running Python based frameworks. The Python egg is built in
[build]/src/python/dist (where [build] represents a remote build
directory if any).


Running Mesos before Installing
===============================

After running 'make' but before running 'make install' you can run any
of the binaries but certain environment variables must be set up first
(see [build]/bin/mesos-build-env.sh.in). It's advisable to run the
binaries by using the wrapper scripts provided in [build]/bin. Note
that these scripts also have a GDB variant that starts the binaries in
GDB when you want to debug.


Examples and Tests
==================

After running 'make check' there will be a collection of examples and
tests that get built. Check out [build]/src/examples and
[build]/src/examples/java and [build]/src/examples/python. In
addition, see [build]/bin for scripts that can run the tests and also
launch the tests in GDB.


Hadoop
======

Included in the distribution is a runnable tutorial on using Hadoop on
Mesos (./hadoop/TUTORIAL.sh). Try it out!


Installing
==========

Note that 'make install' may require superuser privileges. Consider
changing the installation prefix (i.e., the '--prefix=...'
configuration option) or doing 'make install DESTDIR=...'.
