[FIXED] how to exclude opengl32sw.dll from pyqt5 library when using pyinstaller?

Issue

How to write the correct syntax for excluding opengl32sw.dll from pyqt5.

I have tried using exclude in the spec file but its not working.

excludes=['cryptography','PyQt5/bin/opengl32sw.dll']

Solution

The exclude command only works for Python modules and not for DLLs. I think an easy but dirty way in here is to create a virtualenv and manually deleting the DLLs you don't need.

Another way which is more complicated is to locate the PyQt's hook file located in <Python_Path>\lib\site-packages\PyInstaller\utils\hooks\qt.py and disable the line which bundles opengl32sw.dll file:

# Gather required Qt binaries, but only if all binaries in a group exist.
def get_qt_binaries(qt_library_info):
    binaries = []
    angle_files = ['libEGL.dll', 'libGLESv2.dll', 'd3dcompiler_??.dll']
    binaries += find_all_or_none(angle_files, 3, qt_library_info)

    # comment the following two lines to exclude the `opengl32sw.dll`
    # opengl_software_renderer = ['opengl32sw.dll']
    # binaries += find_all_or_none(opengl_software_renderer, 1, qt_library_info)

    # Include ICU files, if they exist.
    # See the "Deployment approach" section in ``PyInstaller/utils/hooks/qt.py``.
    icu_files = ['icudt??.dll', 'icuin??.dll', 'icuuc??.dll']
    binaries += find_all_or_none(icu_files, 3, qt_library_info)

    return binaries
