Issue #3299 has been updated by Romulo Ceccon. Now (r27854) the makefile looks correct on Windows and Linux. Thank you, Nobu. However, invoking "autoconf & ./configure & make" (or "win32\configure & nmake" on Windows) produces an empty revision.h. I guess this is as designed? How am I supposed to generate revision.h so that a "ruby -v" will return something like "ruby 1.8.8dev (2010-05-16 ruby_1_8 27854) [...]"? ---------------------------------------- http://redmine.ruby-lang.org/issues/show/3299 ---------------------------------------- http://redmine.ruby-lang.org
