    I want to use jpeg2000.
    There is a link below.
    link text
    I am trying to build this to create a lib file, but the build button is not activated even when I open the project in qt.
    Why is this and what should I do?

      Are you really using Qt4? Otherwise you have to port the build scripts to your current Qt version first.

      Qt Online Installer direct download: https://download.qt.io/official_releases/online_installers/
      Visit the Qt Academy at https://academy.qt.io/catalog

          Hi!

          What @Christian-Ehrlicher is referring to is the Qt version that this project -you're trying to use- uses, it uses Qt4, check its CMakeLists.txt.

          You're unable to build it because you do not have Qt4. So you either have to install Qt4, which I wouldn't do, or you could do as @Christian-Ehrlicher suggested:

          you have to port the build scripts to your current Qt version first.
