I am trying to rebuild lyx with QT5 enabled instead of QT4.
The build is fine and it seems to start fine, but opening new windows
like "open file" only produces a blank and black window.
At running I see only this output, that is not clear if it is related
QXcbShmImage: shmget() failed (88: Function not implemented) for size
1407600 (690x510)
QXcbShmImage: shmget() failed (88: Function not implemented) for size
518976 (318x408)
Gtk-Message: GtkDialog mapped without a transient parent. This is
discouraged.
QXcbShmImage: shmget() failed (88: Function not implemented) for size
12000 (100x30)
and at build time there is a new warning coming from the compiler
/usr/include/qt5/QtGui/qtransform.h: In member function ‘QTransform&
QTransform::operator=(QTransform&&)’:
/usr/include/qt5/QtGui/qtransform.h:81:46: warning: ‘void* memcpy(void*,
const void*, size_t)’ writing to an object of type ‘class QTransform’
with no trivial copy-assignment; use copy-assignment or
copy-initialization instead [-Wclass-memaccess]
81 | { memcpy(this, &other, sizeof(QTransform)); return *this; }
| ^
Anyone had similar problem with other programs ?
Regards
Marco
