Package: libqt5core5a Version: 5.4.2+dfsg-4 Severity: normal Dear Maintainer,
I've upgraded the Plasma desktop to Plasma 5, and the new desktop fails to start. Looking into the problem I've realized that several components (kwin_x11, plasmashell, several of the systemsettings5 modules...) finish showing the message "This program requires an X86 processor that supports SSE2 extension, at least a Pentium 4 or newer" in the console. I've also checked that a non-kf5 program such as 2048-qt also fails to start with the same message. As per http://lists.qt-project.org/pipermail/development/2013-December/014530.html I understand that all or some Qt5 packages are built with SSE2 requirement enabled. >From that link and from experimentation, I think the crashes only occur in >programs that use QML. For instance, the KF5 version of KWrite and Konsole work fine. I understand a machine such as this Celeron is ancient, but maybe it would be possible (and worthwhile) to provide some kind of dual/conficting packages for some of those libraries, with and without the SSE2 requirements. This is just a test machine for me, it's not like I need this, but after a little discussion on #debian-kde, I thought it was worth a bug report ;) I'm reporting this to libqt5core5a since seems to be about a general Qt5 thing. Cheers, and thanks for all the great work you all do! * What led up to the situation? Upgrading Plasma 4 to Plasma 5 in Sid, on an old Celeron machine. * What exactly did you do (or not do) that was effective (or ineffective)? Starting a Plasma 5 session. * What was the outcome of this action? Several things crash. * What outcome did you expect instead? Desktop showing at least partially. -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: i386 (i686) Kernel: Linux 4.0.0-2-686-pae (SMP w/1 CPU core) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libqt5core5a depends on: ii libc6 2.21-0experimental0 ii libgcc1 1:5.1.1-22 ii libglib2.0-0 2.45.3-1 ii libicu52 52.1-9 ii libpcre16-3 2:8.35-7 ii libstdc++6 5.1.1-22 ii zlib1g 1:1.2.8.dfsg-2+b1 Versions of packages libqt5core5a recommends: pn qttranslations5-l10n <none> Versions of packages libqt5core5a suggests: ii libthai0 0.1.22-2 -- no debconf information -- To UNSUBSCRIBE, email to debian-qt-kde-requ...@lists.debian.org with a subject of "unsubscribe".
