Comprehensive Installation

DeltaCode requires Python 3.6+ and is tested on Linux, Mac, and Windows.
Make sure Python 3.6 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:

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

Prerequisites

DeltaCode needs a Python 3.6+ interpreter.

• On Linux:

Use your package manager to install python3.6.
If Python 3.6 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 3.6 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:

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