[Development] Building Qt documentation with developer-build

[Mitch Curtis]

Did you set LLVM_INSTALL_DIR before building Qt? If you check the build log you should see an error message related to the failure to build qdoc.

If you forgot LLVM_INSTALL_DIR and are trying to build qdoc separately rather than with the rest of Qt, you might run into https://bugreports.qt.io/browse/QTBUG-66366, in which case you’ll need to rebuild *all of Qt*, unfortunately.

    Hi,
    
    While trying improve the documentations to fix QTBUG-32064 I've stumbled
    over problems invoking qdoc.
    
    I'd like to use my developer-build to check the result of my changes but
    qdoc seems to have been skipped when building with --developer-build.
    
    "make docs" from within my shadow build directory fails:
    
    /Users/njeiseck/projects/qt/build/5.12.0-alpha1/qtbase/src/corelib/qdoc_wrapper.sh: line 12: /Users/njeiseck/projects/qt/build/5.12.0-alpha1/qtbase/bin/qdoc: No such file or directory
    /Users/njeiseck/projects/qt/build/5.12.0-alpha1/qtbase/src/corelib/qdoc_wrapper.sh: line 12: exec: /Users/njeiseck/projects/qt/build/5.12.0-alpha1/qtbase/bin/qdoc: cannot execute: No such file or directory
    make[6]: *** [prepare_docs] Error 126

    make[2]: *** [module-qtbase-prepare_docs] Error 2
    make[1]: *** [html_docs] Error 2
    make: *** [docs] Error 2
    
    Seems that qdoc was not build at all. Building qdoc as described on
    https://wiki.qt.io/Building_Qt_Documentation does not work.
    
    I've not found any special qdoc configure options so what am I doing
    wrong?
    
    This is my configure line:
    
    ../../qt512/configure -developer-build -opensource -nomake examples -nomake tests -skip qtwebchannel -skip qtscript -skip qt3d -skip qtdatavis3d -skip qtremoteobjects -skip qtserialport -skip qtvirtualkeyboard -skip qtwebengine -opensource -confirm-license
    
    Any help is appreciated!
    
    Nils
