/tools/synopsys/linux/syn/bin/dc_view_exec: error while loading shared libraries: libncurses.so.4: cannot open shared object file: No such file or directory
There is a simple alternative. In /usr/lib, there is a different vesion of libncurses named libncurses.so.5, just make a symbol link using the following command: ln -s libncurses.so.5 libncurses.so.4 in the directory.
