If you try to compile x11-libs/qt-core this warning comes up NOTICE: Qt will not be built with XShape support. As a result, drag-and-drop in the Qt Designer will NOT work. We recommend that you enable XShape support by passing the -xshape switch to ./configure. I guess it would be a good idea to pass xshape as use flag or enable this switch by default on configure Reproducible: Always Steps to Reproduce: 1.emerge x11-list/qt-core-4.4.2
XShape support is enabled in qt-gui and qt-xmlpatterns, and as a result drag-and-drop in Qt-Designer works. Therefore closing as invalid.
I got this error message too. I do not understand why this is not a bug when there is a warning that something will not work, but then it works anyway.
Because the only package that actually requires xshape is qt-gui and qt-xmlpatterns. None of the rest dont use that switch. Therefor is invalid because you alreay have "xshape" support . Try to emerge qt-gui and qt-xmlpatterns and notice the configure switches.
Then why is it OK that qt-core shows that warning message? The user will think that something is wrong and needs to be fixed.
There is nothing wrong. all the qt splitted packages are using the same configure script. Since we have -no-xshape on qt-core, qt-core complains but we dont care at all since qt-core doesnt make use of xshape support. As I said before qt-gui and qt-xmlpatterns need that and it is already enabled.
In my opinion, showing that warning message is not the ideal way to inform the user that "There is nothing wrong.".
We didnt write that warning message. It 's an upstream message and we cant do anything abou that. However this bug is invalid anyway, I dont need to explain something else :)
Of course something can be done about it. The misleading warning message about xshape can be removed from the packages that have nothing to do with xshape. If I recall correctly, ebuilds can apply patches, so it should be easy.
