What are the configures of officially built Qt

  • I downloaded from the following address:
    I need to check if the officially downloaded Qt version contains zlib library, or just uses the system.
    If Qt bundles zlib library, how could other out-of-source module link the zlib?

    The precompiled one uses the system zlib on linux at least. I checked my install for you:

    [shockwave] /opt/Qt/5.8/gcc_64/lib > ldd
   => /usr/lib/ (0x00007fe51221c000)
   => /opt/Qt/5.8/gcc_64/lib/ (0x00007fe511d83000)
   => /opt/Qt/5.8/gcc_64/lib/ (0x00007fe5119cb000)
   => /opt/Qt/5.8/gcc_64/lib/ (0x00007fe50ffe8000)
   => /usr/lib/ (0x00007fe50fde4000)
   => /usr/lib/ (0x00007fe50fbdc000)
   => /usr/lib/ (0x00007fe50f9c5000)
   => /usr/lib/ (0x00007fe50f7c3000)
   => /usr/lib/ (0x00007fe50f4b0000)
   => /usr/lib/ (0x00007fe50f128000)
   => /usr/lib/ (0x00007fe50ee15000)
   => /usr/lib/ (0x00007fe50ebfe000)
   => /usr/lib/ (0x00007fe50e85a000)
            /lib64/ (0x00007fe51243a000)
   => /usr/lib/ (0x00007fe50e5e7000)

    As you can see it links to /usr/lib/

    My guess is the default on windows is the internal Qt zlib since it doesn't install a separate zlib on windows as part of the Qt installer.
