I'm not running Windows Defender or any software for that matter on my test instance of Server 2008.
I tried running GDB, but the setup executable doesn't have any debugging symbols. Is there a download link somewhere for the latest compiled cygwin setup that includes these symbols?

Reading symbols from setup-x86_64.exe...(no debugging symbols found)...done. (gdb) I won't be able to debug it further unless I have that... I guess. The original log I posted is what you get when I redirect the output to a file with this at the very end of the command " > Cygwin64_Setup.log" -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
