Cygwin installation note:Hand installation over to elevated child process

Question

I am attempting to install Cygwin as a precursor to installing gcc 6.3.0 on a Windows 10 64-bit machine. I am following instructions I found here.

When I use the following line to install Cygwin packages (Step 2 at the above link):

C:\cygwin64>setup-x86_64.exe -q -P wget -P gcc-g++ -P make -P diffutils -P libmpfr-devel -P libgmp-devel -P libmpc-devel

I receive the following message in the Windows command window:

C:\cygwin64>note: Hand installation over to elevated child process.
_

The cursor is positioned under the C in C:\cygwin64 as shown above and is flashing. It has remained that way for approximately one hour.

Does this simply mean that the computer is taking a long time to install Cygwin packages. Or does it mean the Cygwin installation has failed and I need to try something else? Or is the computer waiting for me to type something into the Windows command window from the keyboard? If the third possibility is the case, what am I supposed to type?

The instructions at the link above seem to be quite thorough, but do not mention this message. Nor can I locate any suggestions by searching the internet. The instructions also suggest the installation may take as little as 15 minutes. So, after waiting an hour I am thinking there is something wrong.

Thank you for any advice.

PS.

I did find a message here.

that kind of seems to suggest the Cygwin installation was successful:

if the elevation was successful.  In that case the stdout log now prints

  note: Hand installation over to elevated child process.

But if that is the case why does the directory not reappear in the Windows command window like this: C:\cygwin64> instead of simply having the cursor flashing on a new line without the directory displayed?

Answer 1

After waiting approximately three hours I decided to assume the above message mentioning the elevated child process meant everything was fine even though the folder never reappeared in the Windows command window. I proceeded with the installation of gcc 6.3.0 using the cygwin64 terminal and closed the Windows command window. After completing all of the installation steps outlined within the instructions at the first link in my question post above I obtained the correct answer to the suggested test using the file test.cpp. Therefore, I appear to now have a function installation of the latest version of gcc on the Windows 10 64-bit machine. For that reason I decided to go ahead and post this as an answer instead of adding it to my question.
