5 years ago On Linux systems GR uses the Qt based output gksqt by default. Based on the error messages I would say there is no compatible libqt5 installed on your system and the libstdc++ does not provide the required CXXABI version 1.3.9.
To avoid this problem you might try to use a different workstation type, for example use the x11 output instead of gksqt:
export GKS_WSTYPE=x11
python -i -c "from gr.pygr import mlab; mlab.plot(range(100), lambda x: x**2)"If you want to use the qt output please make sure that you have the Qt5 libraries installed on your machine. As we built the debian binary distribution of GR on debian stable you probably need at least debian stable to run them. If you are using an older debian version you can build the GR runtime from source:
git clone https://github.com/sciapp/gr.git
sudo make self
When running the example
python -c "from gr.pygr import mlab; mlab.plot(range(100), lambda x: x**2)"on debian in python 3.5, I get the following warnings:/home/IPP-HGW/dboe/anaconda2/envs/py35/lib/python3.6/site-packages/gr/bin/gksqt: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5: no version information available (required by /home/IPP-HGW/dboe/anaconda2/envs/py35/lib/python3.6/site-packages/gr/bin/gksqt) /home/IPP-HGW/dboe/anaconda2/envs/py35/lib/python3.6/site-packages/gr/bin/gksqt: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5: no version information available (required by /home/IPP-HGW/dboe/anaconda2/envs/py35/lib/python3.6/site-packages/gr/bin/gksqt) /home/IPP-HGW/dboe/anaconda2/envs/py35/lib/python3.6/site-packages/gr/bin/gksqt: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by /home/IPP-HGW/dboe/anaconda2/envs/py35/lib/python3.6/site-packages/gr/bin/gksqt) /home/IPP-HGW/dboe/anaconda2/envs/py35/lib/python3.6/site-packages/gr/bin/gksqt: /usr/lib/x86_64-linux-gnu/libQt5Gui.so.5: no version information available (required by /home/IPP-HGW/dboe/anaconda2/envs/py35/lib/python3.6/site-packages/gr/bin/gksqt) /home/IPP-HGW/dboe/anaconda2/envs/py35/lib/python3.6/site-packages/gr/bin/gksqt: /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5: no version information available (required by /home/IPP-HGW/dboe/anaconda2/envs/py35/lib/python3.6/site-packages/gr/bin/gksqt) /home/IPP-HGW/dboe/anaconda2/envs/py35/lib/python3.6/site-packages/gr/bin/gksqt: /usr/lib/x86_64-linux-gnu/libQt5Network.so.5: no version information available (required by /home/IPP-HGW/dboe/anaconda2/envs/py35/lib/python3.6/site-packages/gr/bin/gksqt) connect: Connection refused GKS: can't connect to GKS socket application Did you start 'gksqt'?
