    I've created my first dll in Qt, everithing works fine but now I'd like to assign the file version, so I wrote in .pro file this :
    VERSION = 1.0.0.0
    Now when I build the DLL the name of file change from mylibrary.dll to mylibrary1.dll.

    If I change the version to:
    VERSION = 2.0.0.0
    ..the compiled file name get the mylibrary2.dll.

    Is it correct ?????
    Why?

    In this whay when I'll change the Major Number I'll have to change the exe to load a differen library....

      Hi,

      Usually when a library changes its major version it means there are breaking changes so a rebuild of the application is needed anyway.

      Minor and patch versions are meant to replace current versions without rebuilding your application unless you want to make use of a new API provided by a new minor release.

        Is it correct ?????
        Why?

        Why not? What do you think is wrong?

          Hi @SGaist , @Christian-Ehrlicher ,
          you are right, I never imagined it was so good.
          I thought I had to specify it somewhere... But, thanks for your FAST reply.
