This page contains nightly builds of Orange 2.7 from the code repository. These are typically stable and we recommend using them.

Orange 3.0 is in early stages of development. Those interested can find it on GitHub.


Mac OS X

  • Bundle: Orange Snapshot
    This is an universal bundle with everything packed in and ready for an unadvanced user.
  • easy_install/pip:
    Orange is available as a PyPi package. To install run
    easy_install numpy && easy_install orange

Building from source

To build and install Orange you can use the in the root orange directory (requires GCC, Python and numpy development headers). To use it unpack the nightly sources and run:

python build
sudo python install

This will also install orange-canvas script so you can start Orange Canvas from the command line.

To install orange locally run:

python install --user

This will install orange in /home/<username>/.local/lib/pythonX.Y/site-packages/orange/.

make (for developers)

Source distribution also includes makefiles for Linux and Mac OS X and project files for MS Visual Studio 2008. To compile Orange, you will need an appropriate compiler, Python and NumPy.

See building from source wiki page for more information.

C4.5 files

We have no rights to distribute the original C4.5 in any form, but we can provide assistance for building an Orange plug-in from the sources you download yourself from the Ross Quinlan's site. The files required for compiling C4.5 are here and instructions here.
