Comprehensive Installation

DeltaCode requires Python 2.7.x and is tested on Linux, Mac, and Windows. Make sure Python 2.7 is installed first.

System Requirements

• Hardware : DeltaCode will run best with a modern X86 processor and at least 1GB of RAM and 250MB of disk.

• Supported operating systems : DeltaCode should run on these OSes:

  1. Linux: on most recent 64-bit Linux distributions (32-bit distros are only partially supported),
  2. Mac: on recent Mac OSX (10.6.8 and up),
  3. Windows: on Windows 7 and up (32- or 64-bit) using a 32-bit Python.

Prerequisites

DeltaCode needs a Python 2.7 interpreter.

• On Linux:

  Use your package manager to install python2.7. If Python 2.7 is not available from your package manager, you must compile it from sources.

  For instance, visit https://github.com/dejacode/about-code-tool/wiki/BuildingPython27OnCentos6 for instructions to compile Python from sources on Centos.

• On Windows:

  Use the Python 2.7 32-bit (e.g. the Windows x86 MSI installer) for X86 regardless of whether you run Windows on 32-bit or 64-bit. DO NOT USE Python X86_64 installer even if you run 64 bit Windows.

  Download Python from this url: https://www.python.org/ftp/python/2.7.14/python-2.7.14.msi

  Install Python on the c: drive and use all default installer options. See the Windows installation section for more installation details.

• On Mac:

  Download and install Python from this url:

  https://www.python.org/ftp/python/2.7.14/python-2.7.14-macosx10.6.pkg
