Qt5 would crash if you used the accessibility use flag. So, I disabled it from qt-gui, qt-widgets and qt-declarative. Qt-gui and Qt-Widgets compiled fine with accessibility disabled but not Qt-Declarative. anager_p.o -L/usr/X11R6/lib64 -L/var/tmp/portage/x11-libs/qt-declarative-5.0.0/work/qtdeclarative-opensource-src-5.0.0_build/lib -lQt5Qml -lQt5Network -lQt5Gui -lQt5Core -lpthread -lQt5Network -lQt5Core -lQt5V8 -lpthread -lGL .obj/debug-shared/qquickitem.o: In function `QQuickItem::focusInEvent(QFocusEvent*)': qquickitem.cpp:(.text+0xe37): undefined reference to `vtable for QAccessibleEvent' qquickitem.cpp:(.text+0xe61): undefined reference to `QAccessible::updateAccessibility(QAccessibleEvent*)' .obj/debug-shared/qquickitem.o: In function `QQuickItemPrivate::setEffectiveVisibleRecur(bool)': qquickitem.cpp:(.text+0x63f0): undefined reference to `vtable for QAccessibleEvent' qquickitem.cpp:(.text+0x6422): undefined reference to `QAccessible::updateAccessibility(QAccessibleEvent*)' .obj/debug-shared/qquickwindow.o: In function `QQuickWindow::accessibleRoot() const': qquickwindow.cpp:(.text+0x2b1): undefined reference to `QAccessible::queryAccessibleInterface(QObject*)' .obj/debug-shared/qquicktextinput.o: In function `QQuickTextInputPrivate::emitCursorPositionChanged()': qquicktextinput.cpp:(.text+0x6018): undefined reference to `vtable for QAccessibleEvent' qquicktextinput.cpp:(.text+0x605d): undefined reference to `QAccessible::updateAccessibility(QAccessibleEvent*)' .obj/debug-shared/qquicktextinput.o: In function `QQuickTextInputPrivate::internalSetText(QString const&, int, bool)': qquicktextinput.cpp:(.text+0x7bb3): undefined reference to `vtable for QAccessibleEvent' qquicktextinput.cpp:(.text+0x7c63): undefined reference to `QAccessible::updateAccessibility(QAccessibleEvent*)' .obj/debug-shared/qquicktextinput.o: In function `QAccessibleTextCursorEvent::~QAccessibleTextCursorEvent()': qquicktextinput.cpp:(.text._ZN26QAccessibleTextCursorEventD2Ev[_ZN26QAccessibleTextCursorEventD5Ev]+0x3): undefined reference to `vtable for QAccessibleEvent' .obj/debug-shared/qquicktextinput.o: In function `QAccessibleTextCursorEvent::~QAccessibleTextCursorEvent()': qquicktextinput.cpp:(.text._ZN26QAccessibleTextCursorEventD0Ev[_ZN26QAccessibleTextCursorEventD5Ev]+0x3): undefined reference to `vtable for QAccessibleEvent' .obj/debug-shared/qquicktextinput.o: In function `QAccessibleTextUpdateEvent::~QAccessibleTextUpdateEvent()': qquicktextinput.cpp:(.text._ZN26QAccessibleTextUpdateEventD2Ev[_ZN26QAccessibleTextUpdateEventD5Ev]+0x49): undefined reference to `vtable for QAccessibleEvent' qquicktextinput.cpp:(.text._ZN26QAccessibleTextUpdateEventD2Ev[_ZN26QAccessibleTextUpdateEventD5Ev]+0x72): undefined reference to `vtable for QAccessibleEvent' .obj/debug-shared/qquicktextinput.o: In function `QAccessibleTextUpdateEvent::~QAccessibleTextUpdateEvent()': qquicktextinput.cpp:(.text._ZN26QAccessibleTextUpdateEventD0Ev[_ZN26QAccessibleTextUpdateEventD5Ev]+0x49): undefined reference to `vtable for QAccessibleEvent' .obj/debug-shared/qquicktextinput.o:(.data.rel.ro._ZTV26QAccessibleTextCursorEvent[vtable for QAccessibleTextCursorEvent]+0x20): undefined reference to `QAccessibleEvent::accessibleInterface() const' .obj/debug-shared/qquicktextinput.o:(.data.rel.ro._ZTV26QAccessibleTextUpdateEvent[vtable for QAccessibleTextUpdateEvent]+0x20): undefined reference to `QAccessibleEvent::accessibleInterface() const' .obj/debug-shared/qquicktextinput.o:(.data.rel.ro._ZTI26QAccessibleTextCursorEvent[typeinfo for QAccessibleTextCursorEvent]+0x10): undefined reference to `typeinfo for QAccessibleEvent' .obj/debug-shared/qquickaccessibleattached.o: In function `QQuickAccessibleAttached::QQuickAccessibleAttached(QObject*)': qquickaccessibleattached.cpp:(.text+0x5d): undefined reference to `vtable for QAccessibleEvent' qquickaccessibleattached.cpp:(.text+0x82): undefined reference to `QAccessible::updateAccessibility(QAccessibleEvent*)' .obj/debug-shared/moc_qquickaccessibleattached_p.o: In function `QQuickAccessibleAttached::qt_metacall(QMetaObject::Call, int, void**)': moc_qquickaccessibleattached_p.cpp:(.text+0x33e): undefined reference to `vtable for QAccessibleEvent' moc_qquickaccessibleattached_p.cpp:(.text+0x364): undefined reference to `QAccessible::updateAccessibility(QAccessibleEvent*)' moc_qquickaccessibleattached_p.cpp:(.text+0x492): undefined reference to `vtable for QAccessibleEvent' .obj/debug-shared/moc_qquickaccessibleattached_p.o:(.data.rel+0x0): undefined reference to `QAccessible::staticMetaObject' collect2: ld returned 1 exit status make[2]: *** [../../lib/libQt5Quick.so.5.0.0] Error 1 make[2]: Leaving directory `/var/tmp/portage/x11-libs/qt-declarative-5.0.0/work/qtdeclarative-opensource-src-5.0.0_build/src/quick' make[1]: *** [sub-quick-make_first-ordered] Error 2 make[1]: Leaving directory `/var/tmp/portage/x11-libs/qt-declarative-5.0.0/work/qtdeclarative-opensource-src-5.0.0_build/src' make: *** [sub-src-make_first] Error 2 Reproducible: Always Steps to Reproduce: 1.

Indeed, as accessibility use flag is enabled by default, one would expect it to work. At least a message that user has to run accessibility D-BUS agent (otherwise any Qt5 app crashes) would be helpful, or, please, do not enable it by default

Created attachment 335250 [details] Patch for qt-gui ebuild to store accessibility flag QT_NO_ACCESSIBILITY seems to be required in gentoo-config.h to compile all other modules, that depend on qt-gui, without accessibility support
Should be fixed now. Please re-emerge qt-gui:5 before re-trying. Thanks!
(In reply to comment #7) > Should be fixed now. Please re-emerge qt-gui:5 before re-trying. > Thanks! Thank you! Since I went the same way (in my private overlay), I can point that there has to be code to remove QT_NO_ACCESSIBILITY from config. Also, ebuild shall remove "accessibility" from QT_CONFIG in /usr/lib64/qt5/mkspecs/qconfig.pri. And, naturally, put it back in case of recompilation. Otherwise compilation of, at least, qt-webkit fails
