node-embed

Purpose of this repository

This repository aims at demonstrating the usage of the shared library API in Node.js' implementation as of version 9.0.0, as well as the new, extended implementation of said API proposed in this Node.js fork. This repository is a work in progress in the "Advanced Development in C++" project seminar at Hasso Platter Institute's chair of Computer Graphics Systems.

Dependency Setup

Qt

Make sure you have the Qt Version 5.9 or newer installed. You can download it from the official website. If you're on Ubuntu, you can use the beineri/opt-qt591-trusty PPA and need the following packages:

• qt59base
• qt59declarative
• qt59quickcontrols2

Node.js

Clone this repository:

git clone git@github.com:hpicgs/node-embed.git

For all of the examples to work, you will need to clone node.js from here into the externals folder in this repo's root directory and build it:

cd externals
git clone git@github.com:hpicgs/node.git node
cd node
./configure --shared
make -j4
cd ../..

Node.js modules

Install the required Node.js modules by running: npm install.

cpplocate

Install cpplocate. Here's how it could look like:

cd /tmp
git clone https://github.com/cginternals/cpplocate.git
cd cpplocate
mkdir build
cd build
cmake ..
cmake --build .
sudo make install

Building the project

We use cmake to build this project. If you want, you can build it in a dedicated build directory, but beware that the cli-app has to be run from the repo's root directory to work completely.

Windows

Make sure you have Qt installed for the Visual Studio compiler.

cmake -G "Visual Studio 15 2017 Win64" -DCMAKE_PREFIX_PATH='C:\Qt\Qt[VERSION]\[VERSION]\msvc2017_64\lib\cmake' .
cmake --build .

Linux

If you're on the Windows Subsystem for Linux, you'll have to execute the following in addition:

execstack -c externals/node/out/Release/lib.target/libnode.so.61
execstack -c externals/node/out/Release/obj.target/libnode.so.61

./configure
# Adjust CMAKE_PREFIX_PATH (last line) in .localconfig/default to include the Qt cmake directory,
# i.e. /opt/qt59/lib/cmake/Qt5
./configure
cmake --build build

Mac

cmake . -DCMAKE_PREFIX_PATH=[QT INSTALL DIR]/[QT_VERSION]/clang_64
make

Running the application

Executing cmake will create three applications, which can be executed like so:

Windows

./node-qt-rss.exe
./node-lib-qt-rss.exe
./node-lib-cli.exe

Linux

./node-qt-rss
./node-lib-qt-rss
./node-lib-cli

MacOS

./node-qt-rss.app/Contents/MacOS/node-qt-rss
./node-lib-qt-rss.app/Contents/MacOS/node-lib-qt-rss
./node-lib-cli.app/Contents/MacOS/node-lib-cli
