Install so file in ubuntu 18.4 I wrote a simple application in python and compiled it with cython, which generated `.so` files as shown below: > $ ls -l > total 2040 -rw-r--r-- 1 groot groot 486 Jun 14 15:50 compile.py > -rwxr-xr-x 1 groot groot 349232 Jun 14 17:12 CopyDebugThread.cpython-36m-x86_64-linux-gnu.so > -rwxr-xr-x 1 groot groot 491040 Jun 14 17:12 CopyDialog.cpython-36m-x86_64-linux-gnu.so > drwxrwxr-x 2 groot groot 4096 Jun 10 21:09 images > -rwxr-xr-x 1 groot groot 84224 Jun 14 17:12 Main.cpython-36m-x86_64-linux-gnu.so > -rwxr-xr-x 1 groot groot 403424 Jun 14 17:12 MainWindow.cpython-36m-x86_64-linux-gnu.so > -rw-r--r-- 1 groot groot 12 Jun 14 17:43 run.py > -rwxr-xr-x 1 groot groot 739760 Jun 14 17:13 UiMainWindow.cpython-36m-x86_64-linux-gnu.so 1. How can I run this project as a real application, installed in my Ubuntu 18.04 ? 2. Is it possible ? 3. Or do I import it into another python file, then run the python file?

`.so` files are dynamic libraries, they do not run on their own, but get loaded from other programs. You can either load them from your local folder, or put it into a folder listed in your PATH variable and load it from another program in a different directory.
