            Did you check that you have all the dependencies dev packages installed ?

                    Silly question but is your system multi arch ?

                    On a side note, if you don't need QtWebEngine, you can also skip its build.

                      No, I have two system 32 and 64 bit.
                      The behavior is the same on both distribution.
                      I want to upgrade to this version because of QtWebEngine.

                        One thing that is strange is that I don't see any mention of FontConfig on the link like. Can you check that ?

                          Did you mean follow link?
                          http://stackoverflow.com/questions/1594234/qt-linking-error

                          if so, i tried to search same error on google - "/opt/QT/QT_5.7.0/qtwebengine/src/core/Release/obj/src/3rdparty/chromium/skia/libskia_library.a(/opt/QT/QT_5.7.0/qtwebengine/src/core/Release/obj/src/3rdparty/chromium/skia/../third_party/skia/src/fonts/skia_library.SkFontMgr_fontconfig.o):SkFontMgr_fontconfig.cpp:function get_name(_FcPattern*, char const*): error: undefined reference to 'FcPatternGetString'"
                          and found this bug.
                          I am not sure that the fontconfig is the solution.

                            It looks like somehow the dependencies are missing in the link list.

                                I'll check the build of libskia_library.a
