[Solved] Segmentation Fault when opening any Project in 0.19R22039

Post by neutronst4r »

Hello guys,
I am having trouble using version 0.19R22039 on my PC but version 0.18R16146 works fine. Both versions are from the Arch user Repository AUR. Package Names are freecad-appimage and freecad-appimage-git. I think the problem might be the nouveau driver. I cannot use the nvidia drivers (340xx) for my graphics card (Quadro FX 580) without downgrading the X11 Server. Freecad crashes whenever I try to open any project or create a new one. I want to use version 0.19Rxx because there are some features in there that I really need. Please have look at the error messages:

On my Linux system I also use the Nouveau driver and can't switch to the Nvidia driver either.

This happens when the StartPage is shown and if the WebGui module is built with the QtWebEgine module. I don't know if there exists a way to prevent the crash. What solved the problem for me is to build the WebGui module with QtWebkit instead.

So, if you build FreeCAD yourself you should use QtWebkit instead of QtWebEngine. If this is not an option for you then change the startup workbench from "Start" to something else, e.g. Part Design.

Both of these suggestions worked! I have successfully compiled freecad with the following commands.

Code: Select all

mkdir freecad-build
cd freecad-build
cmake -B . -S ../freecad-source -DBUILD_QT5=ON -DPYTHON_EXECUTABLE=/usr/bin/python3 -DFREECAD_USE_QTWEBMODULE="Qt Webkit"
make -j$(nproc --ignore=2)
I did not try this, even thought there seems to be a patch, because I don't want to compile qt5-webengine myself.


Thank you for your help!

These are the steps and I can't see what should be wrong:

Code: Select all

mkdir freecad-build
cd freecad-build
cmake ../freecad-source -DBUILD_QT5=ON -DPYTHON_EXECUTABLE=/usr/bin/python3
make -j$(nproc --ignore=2)
After having cloned the git repo you have the directory freecad-source which is a sub-directory of the cwd. So, in the next step you create the sibling directory freecad-build and switch to it. From within this directory you invoke cmake and pass the relative path to the source directory, i.e. ../freecad-source. This is perfectly the first option described in the cmake help.

Maybe you changed into the freecad-source directory instead of freecad-build?

Yes, probably, nevermind. Just tried again and it worked. Sorry for the trouble and thanks again for the help! :roll:
