Hi Vasil
Which Linux distribution do you use? Why 3.8.1 and not the latest 3.8.4.0?
I use Ubuntu 18.04.6 LTS. I thought GR 3.8.1 was stable. I will install 3.8.4.0 from source now
Do you have qt4-dev and libqwt-dev packages installed on your system? If
you have them but you don't need them for something else then try
removing and then a clean rebuild (e.g. delete the gnuradio's build
directory and start from scratch)
I'll delete libqwt.so.6.1.3.abi1 and libqwt.so.6abi1. And then I will install 3.8.4.0 from source.
soporte@CI-50:/$ ls /usr/lib | grep libqwt
libqwtplot3d-qt5.so
libqwtplot3d-qt5.so.0
libqwtplot3d-qt5.so.0.2
libqwtplot3d-qt5.so.0.2.7
libqwt-qt5.so
libqwt-qt5.so.6
libqwt-qt5.so.6.1
libqwt-qt5.so.6.1.3
libqwt.so.6.1.3.abi1
libqwt.so.6abi1
You may try running the qt test under gdb as well. In the test's shell script instead of valgrind add the following
This is what I see...
