Qt Core binaries

This is a part of Node3D project.

npm i -s deps-qt-core-raub

This dependency package is distributing Qt Core 5.13.0 binaries through NPM for Node.js addons.

• Platforms (x64): Windows, Linux, OSX.
• Library: Qt.
• Linking: dynamic dll-type.

Windows

Before any import of Qt-dependent module, there should be require('deps-qt-core-raub'). On Windows it adds Qt's DLL location to ENV PATH. On Unix it does nothing.

Unix

On Unix, special runtime library directories are not in ENV PATH. The paths to such directories have to be compiled into the node-addon with rpath option.

Adjust binding.gyp:

'variables': {
  'bin': '<!(node -p "require(\'addon-tools-raub\').bin")',
  'qt_core_bin': '<!(node -p "require(\'deps-qt-core-raub\').bin")',
},
...
'targets': [
  {
    'target_name': '...',
    
    'conditions': [
      
      ['OS=="linux"', {
        'libraries': [

      }],

          '-Wl,-rpath,@loader_path/../../deps-qt-core-raub/<(bin)',
        ],
      }],
      
    ],
  },

Preload libraries:

#ifndef WIN32
	#include <dlfcn.h>
#endif
	
	// ... inside some kind of init() function
	#ifdef __linux__
	dlopen("libicui18n.so.56", RTLD_LAZY);
	dlopen("libicuuc.so.56", RTLD_LAZY);
	dlopen("libicudata.so.56", RTLD_LAZY);
	dlopen("libicuio.so.56", RTLD_LAZY);
	dlopen("libicule.so.56", RTLD_LAZY);
	dlopen("libicutu.so.56", RTLD_LAZY);
	dlopen("libQt5Core.so.5", RTLD_LAZY);
	dlopen("libQt5Network.so.5", RTLD_LAZY);
	dlopen("libQt5DBus.so.5", RTLD_LAZY);
	#endif
