Qt Core binaries

This is a part of Node3D project.

npm i -s deps-qt-core-raub

This dependency package is distributing Qt Core 6.8.0 binaries through NPM for Node.js addons.

• Platforms (x64): Windows, Linux, MacOS ARM.
• Libraries: Qt Core.
• 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"', {

          '-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.73", RTLD_LAZY);
	dlopen("libicuuc.so.73", RTLD_LAZY);
	dlopen("libicudata.so.73", RTLD_LAZY);
	dlopen("libicuio.so.73", RTLD_LAZY);
	dlopen("libicule.so.73", RTLD_LAZY);
	dlopen("libicutu.so.73", RTLD_LAZY);
	dlopen("libQt6Core.so.6", RTLD_LAZY);
	dlopen("libQt6Network.so.6", RTLD_LAZY);
	dlopen("libQt6DBus.so.6", RTLD_LAZY);
	#endif

Legal notice

This software uses the Qt library. Qt is legally used under the LGPLv3 (GNU Lesser General Public License) version. It is explicitly stated that Qt Libraries can be used in a commercial closed-source app (if you wish):

In case of dynamic linking, it is possible, but not mandatory, to keep application source code proprietary as long as it is “work that uses the library” – typically achieved via dynamic linking of the library.

These terms and conditions allow using (unmodified) Qt as a shared library (DLL), in a closed-source project.

Qt licensing information (a COPY) is given in a separate file, which also can be found on Qt's official web-site.

The binaries were extracted from installed copy of the framework.
