Hi, Autoconf works fine for me here (cygwin-1.7 on XP). This error looks more like a problem about cygwin and your environment than about ruby. Several messages in cygwin lists suggest that this may be caused by some interference from some antivirus software. http://sourceware.org/ml/cygwin/2007-05/msg00679.html (Eric Blake is the cygwin m4 maintainer) http://sourceware.org/ml/cygwin/2008-03/msg00577.html http://sourceware.org/ml/cygwin-xfree/2008-12/msg00039.html Do you have installed any of the softwares listed in http://cygwin.com/faq/faq.using.html#faq.using.bloda ---------------------------------------- http://redmine.ruby-lang.org/issues/show/1775 ---------------------------------------- http://redmine.ruby-lang.org
