If you want to build ns3, you need to install scons (see

http://www.scons.org). scons takes care of building

the whole source tree using your system compiler. scons

0.91.1 and 0.91.96 have been tested and are known to 

work on linux FC5, Mac os X and MinGW.

To start a build, you can just type 'scons' which

will generate a debug shared build by default, located

in the directory 'build-dir/dbg-shared/bin' and

'build-dir/dbg-shared/lib'.

1) Options

----------

- verbose: if you have install scons 0.91.96, the default

  build output is terse. To get a more verbose output, you

  need to set the 'verbose' variable to 'y'.

Example:

scons verbose=y

2) Targets

----------

- dbg-shared: a debug build using shared libraries.

  The files are built in 'build-dir/dbg-shared/'.

Example:

scons dbg-shared

- dbg-static: a debug build using static libraries

  The files are built in 'build-dir/dbg-static/'.

Example:

scons dbg-static

- opt-shared: an optimized build using shared libraries.

  The files are built in 'build-dir/opt-shared/'.

Example:

scons opt-shared

- opt-static: an optimized build using static libraries.

  The files are built in 'build-dir/opt-static/'.

Example:

scons opt-static

- dbg: an alias for dbg-shared

Example:

scons dbg

- opt: an alias for opt-shared

Example:

scons opt

- all: alias for dbg-shared, dbg-static, opt-shared 

  and opt-static

Example:

scons all

- dist: generate a release tarball and zipfile from the 

  source tree. The tarball and zipfile name are generated

  according to the version number stored in the SConstruct

  file.

Example in SConstruct:

ns3 = Ns3 ()

ns3.name = 'foo'

ns3.version = '0.0.10'

Example command:

scons dist

Example output:

foo-0.0.10.tar.gz

foo-0.0.10.zip

- distcheck: generate a release tarball and zipfile and 

  attempt to run the 'all' target for the release tarball.

Example:

scons distcheck
