Need help for updating Qt to 5.12 - cmake link issue

Need help for updating Qt to 5.12 - cmake link issue

[Hartmut Goebel]

Hi,

I'm stuck on updating QT to 5.12, which is q prerequisite for updating
KDE Framworks to a recent version.

For some of the packages - most of which seem to be rather new to Qt -
build fails since the linker does not find some libraries, e.g when
building qtgamepad:

g++: error: /gnu/store/…-qtgamepad-5.12.5/lib/libQt5Core.so: No such
file or directory

As you can see, this is libQt5core, but the linker want to load it from
the current packages output.

This kind of issues do not occur with most of the "older" packages. I
already tried to find some place to hook in - without success. Any hints?

Here is the package definition for the case one want to reproduce this.

(define-public qtgamepad
  (package (inherit qtsvg)
    (name "qtgamepad")
    (version "5.12.5")
    (source (origin
             (method url-fetch)
             (uri (string-append
"https://download.qt.io/official_releases/qt/"
                                 (version-major+minor version) "/" version
                                 "/submodules/" name "-everywhere-src-"
                                 version ".tar.xz"))
             (sha256
              (base32
               "0czdmmbjc6zpj213pwwgjh0h2awzmrgkqy5gl5a5vk7p8wfz126y"))))
    (arguments
     (substitute-keyword-arguments (package-arguments qtsvg)
       ((#:phases phases)
        `(modify-phases ,phases
           (add-after 'configure 'fail
             (lambda* (#:key outputs #:allow-other-keys)
               #t))))
       ((#:tests? _ #f) #f)))           ; TODO: Enable the tests
    (native-inputs
     `(("perl" ,perl)))
    (inputs
     `(("sdl2" ,sdl2)
       ("qtbase" ,qtbase)))
    (synopsis "x")
    (description "")))

Qt is upgraded to 5.12 on staging :)

There's also qtwayland and 3 others.

I think Nix does it by patching qtbase to tell everything to use either
NIX variables or absolute paths
https://github.com/NixOS/nixpkgs/tree/e36c7e61c39bb78ab6bf0b0894ed418af4ab5f03/pkgs/development/libraries/qt-5/5.12

Good to know, so I can save my time on this. I should have had a look at
staging :-)
