First, I have to create a demo with the following structure:
. Test whether cygwin has been installed.
Run cygwin and enter cygcheck in the pop-up command line window.The-C cygwin command prints the current cygwin version and running status. If the status is OK, cygwin runs normally.
Then input gcc-version, G ++ -- version, make-version, and GDB-version in sequence for testing. If both print the published version information and some description information, I am very happy to tell you, your cygwin installation is complete!
