Geting Source code

git clone https://code.qt.io/qt/qt5.git
cd qt5
git checkout 5.10
  • Initialize the repository using the init-repository script
  Module options:

    --module-subset=<module1>,<module2>...
        Only initialize the specified subset of modules given as the
        argument. Specified modules must already exist in .gitmodules. The
        string "all" results in cloning all known modules. The strings
        "essential", "addon", "preview", "deprecated", "obsolete", and
        "ignore" refer to classes of modules; "default" maps to
        "essential,addon,preview,deprecated", which corresponds with the
        set of maintained modules and is also the default set. Module
        names may be prefixed with a dash to exclude them from a bigger
        set, e.g. "all,-ignore".

perl init-repository --module-subset=essential

Configuring and Building

./configure -developer-build -opensource -nomake examples -nomake tests -prefix <PREFIX-PATH> -debug -recheck-all -confirm-license

Issue

  • QFontDatabase: Cannot find font directory <PREFIX-PATH>/lib/fonts.
    • Description
      QFontDatabase: Cannot find font directory <PREFIX-PATH>/lib/fonts.
  Note that Qt no longer ships fonts. Deploy some (from http://dejavu-fonts.org for example) or switch to fontconfig.
    • Fix:
      Create required folder and put some fonts there
