Singular

I installed 32bit Cygwin, using the "over the internet" option.

I chose to install 'Singular' related packages from the list that was presented, and 'VIOLA', I obtained the following.

Thank you for the "32bit" comment.

THe output shows that your are running Singular-3-1-6 (from the header)
with the libraries of Singular-4-1-2 (from the name of the tar file).
This results in an error because in Singular-4-1-2 the command LIB can take 2 arguments (in Singular-3-1-6 only one).

Possible reasons are:
- the executable Singular.exe from Singular-3-1-6 appears before that of
4-1-2 in your path (try "which Singular" and check the date,
Singular.exe from 4-1-2 is from 2019-05-31 14:22)
- you have cygwin for 64bit, but Singular-4-1-2 is for 32bit
(try "file /bin/ls.exe" or check its properties)
- Singular.exe from 3-1-6 was not overwritten by the tar command: maybe it is write-protected

I have just tried to instal Singular and run it. I had Cwgwin installed but I do not know how I originally installed it. I had the following input and output from what I assume is my effective Cwgwin terminal
