I think that I didn't run at the Cygwin shell. I used a different perl from Cygwin (ActivePerl).

I found out this link: and I am trying to follow the section for Cygwin. This time, I am running at a Cygwin shell however it complains that there is ar file.

Then I launched the setup.exe for Cygwin again to try to install the ar, however I just could not find it at the packages ( it is not easy to find it either, I did search as well and I didn't find a ar file although it found arc, arj, parrot, tar etc). I did some search on internet, and it is really not any information about ar file. Any idea?
