What is QtCored'4'.dll

  • i have built qt 4.7.4 source for vs2010 app
    after qt build, i checked qt/lib folder
    i found QtCore.dll / QrCored.dll but there is not QtCored'4'.dll
    some other program have QtCored4.dll
    what is '4' ?

  • The number '4' - is major version of the library.
    Major version, if you are going to a shared library.
    You have to get the files: bin/Qt{Module}4.dll and lib/Qt{Module}4.lib
    If you have collected Qt statically, the major version is not affixed.
    You should only get lib/Qt{Module}.lib files.

  • oh~ i got it.
    thank you
