Hi, I was installing Zlib through CPAN shell and ran into DLL unlink problem,. If possible, could you display a message to user that it's impossible to install Zlib completerly from cpan prompt. Something like: "In Cygwin environment Windows cannot delete active DLLs. Therefore to to complete Zlib install, exit the CPAN prompt, and run 'make install' by hand under directory ~/.cpan/build/Compress-Zlip-VERSION/." See http://www.cygwin.com/ml/cygwin/2001-12/msg00622.html I'm CC'ing this to Perl 5 porters as well, so that possible other developers hear about this Win32/Cygwin problem as well. JariThread Next
