Issue #9199 has been updated by usa (Usaku NAKAMURA). Note that this problem is not fixed at 2.1.0-rc1, and I think this is a critical showstopper. ---------------------------------------- Bug #9199: win32.h is not installed by '(n)make install) https://bugs.ruby-lang.org/issues/9199#change-43787 Author: arton (Akio Tajima) Status: Assigned Priority: Normal Assignee: Glass_saga (Masaki Matsushita) Category: build Target version: current: 2.1.0 ruby -v: ruby 2.0.0p353 (2013-11-22) [i386-mswin32_100] Backport: 1.9.3: DONTNEED, 2.0.0: REQUIRED I try to install ruby-2.0.0-p353 (also rubytrunk) using 'nmake install' but ruby/win32.h does not include in include directory. cause: tool/rbinstall.rb checks that it's required win32.h by 'unless RUBY_PLATFORM =~ /mswin|mingw|bccwin/. It's ok but current common.mk invokes rbinstall.rb with -r./$(arch)-fake and it only rests 'i386' in RUBY_PLATFORM. I'm not certain the reason of $(arch)-fake, so don't know how to fix it. -- http://bugs.ruby-lang.org/
