$ . configure

but after few second the Ubuntu terminal close, without any message. What happened?

Thanks for your time about my issue

By doing that you're running the configure script in the current shell similar to exec bash -e ./configure or simply source ./configure .

Dot followed by a space is equivalent to the source command , but if you want to execute the configure script in the current directory , you have to add a slash between the dot and configure :

./configure

The bash first spawns a new shell then executes it in the child shell.But if you use the source command or . configure , you're actually executing it instead of the current bash process.So your terminal will get closed after that since there's no shell to give you a prompt.

  • @Dario You have to install g++ for that(sudo apt install g++) .Please check out the required packages in the README or INSTALL.md of the program you're trying to compile to prevent future errors. – Parsa Mousavi Jun 19 '20 at 15:26
