Hello there everybody, This is vijai from bangalore. I tried building openflipper in my xubuntu 16.04.2 LTS. I was able to build it successfully without much issues. But when i tried to use the visual script editor, it crashes with the following error. I am not sure if i am missing something here. Any help is appreciated. vijai@asus:~/DevRepos/OpenFlipper-3.1/build/Build/bin$ ls libOpenMeshCore.a libOpenMeshTools.a libOpenVolumeMesh.a OpenFlipper print.ps vijai@asus:~/DevRepos/OpenFlipper-3.1/build/Build/bin$ ./OpenFlipper ./OpenFlipper: symbol lookup error: /home/vijai/DevRepos/OpenFlipper-3.1/build/Build/lib/plugins/libPlugin-VSI.so: undefined symbol: _ZN9QXmlQueryC1Ev vijai@asus:~/DevRepos/OpenFlipper-3.1/build/Build/bin$ I have attached the ldd output too.
