Segfault after compiling OpenFlipper-Free with Qt 5.6
Hi, I just cloned the OpenFlipper-Free repository (https://www.graphics.rwth-aachen.de:9000/OpenFlipper-Free/OpenFlipper-Free.g...) and compiled it successfully (64bit Linux). However, when I try to run OpenFlipper, I immediately get a Segmentation fault. Could this be due to the fact that I'm using Qt 5.6 (there was a warning about this when running cmake)? If there's any other information I could provide, please let me know. Thanks, Pieter
Hi, we don't support Qt 5.6 yet. There are some modules missing in 5.6 so we need to port things in order to work without these modules. However, can you send a backtrace of the segfault? (Should be generated by OpenFlipper automatically) Maybe we can see what's happening. Best, Jan Möbius On 02.05.2016 14:20, Pieter Barendrecht wrote:

Hi, your backtrace states that you are linking against Qt 4 or a mixture of 4/5. Please do the following steps: Open cmake Set QT5_INSTALL_PATH to your Qt installation dir( e.g. .../Qt-5.5.1/5.5/gcc_64 ) Select all other Qt related entries in cmake and remove them. configure generate. You should not see any other qt4 related entries after this. Then rebuild. On 02.05.2016 13:45, Pieter Barendrecht wrote:

Hi Jan, Thanks for your reply. I tried several paths for QT5_INSTALL_PATH, no luck so far. After I press configure, I don't see anything that mentions the Qt4 libraries, just entries like Qt5Svg_DIR which are set to e.g. /usr/lib64/cmake/Qt5Svg (/usr/lib64 is a symlink to /lib which in turn is a symlink to /usr/lib). However, for some reason a couple of Qt4 libraries are still being used — ldd ./OpenFlipper | grep -i "Qt" libQt5Declarative.so.5 => /usr/lib/libQt5Declarative.so.5 (0x00007f5f849f9000) libQt5OpenGL.so.5 => /usr/lib/libQt5OpenGL.so.5 (0x00007f5f847a1000) libQt5Script.so.5 => /usr/lib/libQt5Script.so.5 (0x00007f5f84310000) libQt5ScriptTools.so.5 => /usr/lib/libQt5ScriptTools.so.5 (0x00007f5f8403d000) libQt5Sql.so.5 => /usr/lib/libQt5Sql.so.5 (0x00007f5f83df6000) libQt5Xml.so.5 => /usr/lib/libQt5Xml.so.5 (0x00007f5f83bbb000) libQt5XmlPatterns.so.5 => /usr/lib/libQt5XmlPatterns.so.5 (0x00007f5f835d1000) libQt5Help.so.5 => /usr/lib/libQt5Help.so.5 (0x00007f5f83335000) libQt5WebKit.so.5 => /usr/lib/libQt5WebKit.so.5 (0x00007f5f80ca2000) libQt5Network.so.5 => /usr/lib/libQt5Network.so.5 (0x00007f5f80936000) libQt5PrintSupport.so.5 => /usr/lib/libQt5PrintSupport.so.5 (0x00007f5f806c5000) libQt5Widgets.so.5 => /usr/lib/libQt5Widgets.so.5 (0x00007f5f7fe4b000) libQt5X11Extras.so.5 => /usr/lib/libQt5X11Extras.so.5 (0x00007f5f7fc47000) libQt5Gui.so.5 => /usr/lib/libQt5Gui.so.5 (0x00007f5f7f4c4000) libQt5Core.so.5 => /usr/lib/libQt5Core.so.5 (0x00007f5f7edfa000) libQtSvg.so.4 => /usr/lib/libQtSvg.so.4 (0x00007f5f7c167000) libQtGui.so.4 => /usr/lib/libQtGui.so.4 (0x00007f5f7b42e000) libQtCore.so.4 => /usr/lib/libQtCore.so.4 (0x00007f5f7af26000) libQt5CLucene.so.5 => /usr/lib/libQt5CLucene.so.5 (0x00007f5f7ac2c000) libQt5Sensors.so.5 => /usr/lib/libQt5Sensors.so.5 (0x00007f5f775eb000) libQt5Positioning.so.5 => /usr/lib/libQt5Positioning.so.5 (0x00007f5f773ab000) libQt5Quick.so.5 => /usr/lib/libQt5Quick.so.5 (0x00007f5f76dc3000) libQt5Qml.so.5 => /usr/lib/libQt5Qml.so.5 (0x00007f5f767d2000) libQt5WebChannel.so.5 => /usr/lib/libQt5WebChannel.so.5 (0x00007f5f765b5000) Note that /usr/lib also contains the Qt5 versions of those libraries (libQt5Svg, libQt5Gui and libQt5Core).

Hi Pieter, Sorry for the late reply. We are still working on 5.6. Currently the git master contains several new patches to deal with this version. It disables some libraries which are not required anymore via cmake. I'm not sure if that fixes your Problem. There are also still Problems on other platforms (VS2015 with internal compiler errors,...) so still some work to do getting 5.6 completly supported.

Thanks for your reply. I tried several paths for QT5_INSTALL_PATH, no luck so far. After I press configure, I don't see anything that mentions the Qt4 libraries, just entries like Qt5Svg_DIR which are set to e.g. /usr/lib64/cmake/Qt5Svg (/usr/lib64 is a symlink to /lib which in turn is a symlink to /usr/lib). However, for some reason a couple of Qt4 libraries are still being used —
ldd ./OpenFlipper | grep -i "Qt" libQt5Declarative.so.5 => /usr/lib/libQt5Declarative.so.5 (0x00007f5f849f9000) libQt5OpenGL.so.5 => /usr/lib/libQt5OpenGL.so.5 (0x00007f5f847a1000) libQt5Script.so.5 => /usr/lib/libQt5Script.so.5 (0x00007f5f84310000) libQt5ScriptTools.so.5 => /usr/lib/libQt5ScriptTools.so.5 (0x00007f5f8403d000) libQt5Sql.so.5 => /usr/lib/libQt5Sql.so.5 (0x00007f5f83df6000) libQt5Xml.so.5 => /usr/lib/libQt5Xml.so.5 (0x00007f5f83bbb000) libQt5XmlPatterns.so.5 => /usr/lib/libQt5XmlPatterns.so.5 (0x00007f5f835d1000) libQt5Help.so.5 => /usr/lib/libQt5Help.so.5 (0x00007f5f83335000) libQt5WebKit.so.5 => /usr/lib/libQt5WebKit.so.5 (0x00007f5f80ca2000) libQt5Network.so.5 => /usr/lib/libQt5Network.so.5 (0x00007f5f80936000) libQt5PrintSupport.so.5 => /usr/lib/libQt5PrintSupport.so.5 (0x00007f5f806c5000) libQt5Widgets.so.5 => /usr/lib/libQt5Widgets.so.5 (0x00007f5f7fe4b000) libQt5X11Extras.so.5 => /usr/lib/libQt5X11Extras.so.5 (0x00007f5f7fc47000) libQt5Gui.so.5 => /usr/lib/libQt5Gui.so.5 (0x00007f5f7f4c4000) libQt5Core.so.5 => /usr/lib/libQt5Core.so.5 (0x00007f5f7edfa000)

Note that /usr/lib also contains the Qt5 versions of those libraries (libQt5Svg, libQt5Gui and libQt5Core). Any ideas? I'm probably overlooking something — I don't have a lot of experience manually changing cmake settings.

Hi,
your backtrace states that you are linking against Qt 4 or a mixture of 4/5. Please do the following steps:
Open cmake Set QT5_INSTALL_PATH to your Qt installation dir( e.g. .../Qt-5.5.1/5.5/gcc_64 ) Select all other Qt related entries in cmake and remove them. configure generate.
You should not see any other qt4 related entries after this. Then rebuild.

Hi,
we don't support Qt 5.6 yet. There are some modules missing in 5.6 so we need to port things in order to work without these modules.
However, can you send a backtrace of the segfault? (Should be generated by OpenFlipper automatically) Maybe we can see what's happening.
Best, Jan Möbius

Hi,
I just cloned the OpenFlipper-Free repository (https://www.graphics.rwth-aachen.de:9000/OpenFlipper-Free/OpenFlipper-Free.g...) and compiled it successfully (64bit Linux). However, when I try to run OpenFlipper, I immediately get a Segmentation fault. Could this be due to the fact that I'm using Qt 5.6 (there was a warning about this when running cmake)? If there's any other information I could provide, please let me know.
Thanks, Pieter
