[sword-devel] Linux: Linking to Sword library with potentially different names

[Tobias Klein]

Hi Greg,

The Sword binding is C++ and the main application is Javascript 
(Electron / Node-JS).

Main application:
https://github.com/tobias-klein/ezra-project

Sword interface:
https://github.com/tobias-klein/ezra-sword-interface


Besides Github the Sword interface is also published on npmjs.com, which 
means it can be easily installed with npm (node package manager).

https://www.npmjs.com/package/ezra-sword-interface

The main application depends on the most recently published version of 
the Sword interface and the dependency is handled by npm.
When installing the dependencies of Ezra Project (see step 2 below) the 
correct version of the Sword interface is automatically installed in the 
project directory (from npmjs.com).

To get Ezra Project and its Sword interface setup/compiled, the 
following steps must be performed (on Debian/Ubuntu):

0) Install tool/library dependencies: nodejs, build-essential, 
libsword-dev, libsqlite3-0
1) Clone Ezra Project (https://github.com/tobias-klein/ezra-project.git)
2) Install dependencies in the Ezra Project directory: Run "npm install" 
in project directory
3) Rebuild C++ dependencies: Run "npm run rebuild-linux" in project 
directory
4) Start ezra project: Run "npm start" in project directory


I should put these instructions on the Wiki pages on Github as well ... 
will do that asap.

Have a blessed Easter celebration! The Lord is risen!

Best regards,
Tobias
