linuxdeployqt.py | A Python based Qt linux deploy tool

linuxdeployqt.py is a Python library. linuxdeployqt.py has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. However linuxdeployqt.py build file is not available. You can download it from GitHub.

linuxdeployqt.py can recursivly resolve shared object (*.so) dependencies of dynamically linked applications. It takes an executable file and find all *.so files linked to it - then for each of these *.so files it finds their dependencies ... and the dependencies of their dependencies - and so forth (hopefully ending at some point). While it, in theory, can resolve dependencies for any executable (but only if ldd can resolve them) - linuxdeployqt.py specializes in doing it for Qt5 binaries because some special care is to be taken if you also want the dependencies of dynamically loaded plugins (Qt plugins, QML imports, etc.). By using the shell utility ldd in a recursive manner linuxdeployqt.py can produce a list of (almost) every *.so dependency a Qt executable relies on. While this approach probably won't work in some scenarios where ldd fails (cross-compiled apps?) - it's filling in a gap that has been around for a long time; Easy deploying of Linux based Qt software - built with Qt Creator. linuxdeployqt.py can output the dependency list in JSON format (to a file or stdout) - to use elsewhere - or create an AppDir and/or AppImage directly. AppDir and AppImage are concepts found in the AppImageKit project which can be explored further here. Basically the AppImageKit makes it possible to build and deploy universal, batteries included, single-file executables that can run on most linux distros without modifications - a welcomed option in these times of one-click-should-solve-everything. For most cases linuxdeployqt.py should be able to find everything needed except for QML loaded dynamically at run time (with e.g.: Qt.createQmlObject()). If these run-time imports are unique (i.e. not imported in other files) these should be added as values to --qml-import parameters (see examples below).
