From: Luis Lavena Date: 2010-02-18T22:38:53+09:00 Subject: [ruby-core:28221] [Bug #2750] build fails on win32/MinGW: "executable host ruby is required." even when --with-baseruby is used Issue #2750 has been updated by Luis Lavena. Christian, Please indicate which source package of 1.9.1 are you using (and where you downloaded) in case was subversion, check if you have the latest release. If using Subversion, also try with 1.9.2 (trunk) and see if the problem persist there. A recommendation: if you have ruby in the path, baseruby will be determined automatically, no need to indicate it, only if you want to use a different ruby version than the one available in the system. Second, please try this format to path: ./configure --with-baseruby="C:/Foo/Bar/Ruby-1.9/bin/ruby.exe" And also verify that "Programs" is actually programs and not Program Files ;-) Good luck, -- Luis Lavena ---------------------------------------- http://redmine.ruby-lang.org/issues/show/2750 ---------------------------------------- http://redmine.ruby-lang.org
