hello community
i try to install the EQT qt on linux but i get this:./EquiTrader-qt--ubuntu64: error while loading shared libraries: libdb_cxx-5.3.so: cannot open shared object file: No such file or directory
can someone help pls.?
Thanks in Advance

Have you installed all dependencies?
It could be you are missing libdb5.3-dev.
You could try to install it with:
sudo apt install libdb5.3-dev
Good luck!
