Developing Gramps on Ubuntu 16.04

Gramps is an open-source genealogy research tool written in Python3.

If you want to develop it on Windows, here are the instructions to do that.

To get started you'll need to read through a lot of documentation.

• Gramps Developer Portal
• Addons Development
• Project Code Structure
• Gramps API documentation

As for Python3 these can help:

• The Python Tutorial
• Python Documentation

Dependencies needed for Gramps

...are listed in the README.md:

EDIT: I just noticed this in the Getting Started and it might work instead of all those individual installations below, but you have to enable source code sources before you can do it: apt-get build-dep gramps

• Graphviz: sudo apt-get install graphviz
• PyICU: 
• install ICU dev package: sudo apt-get install libicu-dev
• and PyICU: pip3 install pyicu --user
• Ghostscript: already installed
• GExiv2: to get rid of the error popup when running Gramps

• sudo apt-get install gir1.2-gexiv2-0.10

Try what you cooked

• download: git clone https://github.com/gramps-project/gramps.git Gramps
• build: python3 setup.py build
• DON'T INSTALL IT! (that would be python3 setup.py install)
• run: python3 Gramps.py
