We've recently moved to GNU Make 3.79.1 (from 3.77) on Windows NT and have noticed that on a large project there is a noticeable drop in speed during the automatic dependency checking which is done at the beginning of a build.
Our dependency checking is done in a standard enough way (a .d file for each object file, with the .d file containing all the dependencies, and all the .d file included from a centralised makefile). The examination of all the dependencies using 3.79.1 takes roughly 140 seconds, where it was about 22 seconds with 3.77. I was just wondering if anyone else had noticed/investigated this behaviour and could provide some pointers in my investigation. (I have scoured the cygwin site, the release notes, this mailing archive and google (web & groups) but no luck thus far). It would be handy if I could pin the slowdown to a specific version of make, but I can't find any cygwin install packages for any version other than 3.79.1-5. Is there an archive anywhere for old cygwin packages (again, I looked but didn't find)? As far as I can see from GNU.org, there were two versions (3.78.1, 3.79) between 3.77 and 3.79.1. Any ideas warmly welcomed, Thanks, John -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
