Multipackage GUI need help setting up spec file

[jag213]

Hello,

I am trying to make two GUIs which use the same packages and would like to use the multipackage option in order to reduce disk space in case I want to scale up the number of GUIs in the future. I am trying to get a simple example working, but am running into problems.

The two GUIs are each a single Pyside2 label, at the moment, with GUI A saying 'Test A' and GUI B saying 'Test B'. I've pasted the code below with the commented lines being the only difference between the two. I am able to make individual spec files for each GUI and get them working with Pyinstaller. However, when I try and use multipackage with the spec file below, GUI_B opens and immediately closes with the error message it can't find python38.dll. GUI_A still works in the multipackage build. Hopefully this is just a error in my spec file, but I can provide additional info if the spec file looks correct. Thanks

    def __init__(self):
        QMainWindow.__init__(self)
        self.setWindowTitle("Tutorial")
        # Menu
        self.menu = self.menuBar()
        self.file_menu = self.menu.addMenu("File")

        #GUI A 
        self.QQ = QLabel('Test A')
        #GUI B 
        #self.QQ = QLabel('Test B')

        self.setCentralWidget(self.QQ)

        # Exit QAction
        exit_action = QAction("Exit", self)
        exit_action.setShortcut("Ctrl+Q")
        exit_action.triggered.connect(qtapp.quit)
        self.file_menu.addAction(exit_action)

        QApplication.quit()

    # for now put GUI in right half of screen

Hmm, looking at the .spec files that are used by out multipackage tests:

• the third argument in tuples given to MERGE() seems to be the path to executable, relative to dist dir
• the EXE()s need to be passed dependencies TOC of the Analysis object that was modified during merge

I.e,

MERGE(
    (a, 'GUI_TestA', os.path.join('GUI_TestA', 'GUI_TestA')),
    (b, 'GUI_TestB', os.path.join('GUI_TestB', 'GUI_TestB'))
)

and

exea = EXE(pyza,
          a.scripts,
          #a.dependencies,
          [],

exeb = EXE(pyzb,
          b.scripts,
          b.dependencies,
          [],

a.dependencies should probably come up empty (because it ought to be the reference package), but it seems to end up with couple of references to itself (in this PySide2 example), which is causing problems - that's why it's commented out...

Also, due to another referencing bug, multipackage currently doesn't seem to work if you have nested resources (binary extensions or data files that reside in package directories; which definitely is the case with PySide2). So you'll either need to use the branch from #5606 or wait until that's merged.

Perfect. Those two solutions together got it working. Thanks for your help
