     int slength = strlen(s)+1;
     len = MultiByteToWideChar(CP_ACP, 0, s, slength, 0, 0);
     wchar_t* buf = new wchar_t[len];
     MultiByteToWideChar(CP_ACP, 0, s, slength, buf, len);

    Install Pygame for Python 2.7 on Windows 64bit

    Check here for pygame wheel.

    My config goes like C:\WinPython-64bit-\python-2.7.10.amd64, so it is a pre-compiled python bundle. The official site lists release only for 32-bit. But it gives the link to a wheel link.

    Basically, this is a personal managed wheel list. Choose the follow wheel and install through pip command

    pip install pygame-1.9.2a0-cp27-none-win_amd64.whl

    depmod will prefer updates/ over kernel/ -- OK!
    You may or may not need to update your initramfs, you should if
    any of the modules installed are part of your initramfs. To add
    support for your distribution to do this automatically send a
    patch against "update-initramfs.sh". If your distribution does not
    require this send a patch with the '/usr/bin/lsb_release -i -s'
    ("Ubuntu") tag for your distribution to avoid this warning.
    Your backported driver modules should be installed now.

    PyInstaller: Tweaking spec file

    Install PyInstaller

    pip install pyinstaller

    Generate spec file

    pyinstaller --onefile foo.py

    Tweak spec file

                 datas=[("myfile.txt", "."),
                        ("mydb.db", ".")
                 hiddenimports=["packaging", "packaging.version", "packaging.specifiers"],

    In one-file mode, no COLLECT is called within spec file, so finally there will be only one exe file generated.

    Generate one-file exe

    pyinstaller foo.spec
