From: Christian Bodt Date: 2010-02-18T20:09:04+09:00 Subject: [ruby-core:28217] [Bug #2750] build fails on win32/MinGW: "executable host ruby is required." even when --with-baseruby is used Issue #2750 has been updated by Christian Bodt. Hi Luis, Thanks for your help, Could you tell me if I understood correctly what 'windows path' you mean? I am using msys+mingw and the standard bash shell to compile. Folling your advice, I tried running the command (as in configue.in line 22) : "RUBYOPT=- 'c:\Programs\ruby-1.9\bin\ruby.exe' -e 'p 42'" It fails in the same way as before (c:\Programs\ruby-1.9\bin\ruby.exe: invalid switch in RUBYOPT: -C (RuntimeError)). The following fails also: > export RUBYOPT=- > ruby.exe -e 'p 42' c:\Programs\ruby-1.9\bin\ruby.exe: invalid switch in RUBYOPT: -C (RuntimeError) Using the windows "cmd.exe" shell, the - option seems to be accepted: >set RUBYOPT=- >ruby.exe -e 'p 42' 42 I think I will try RubyInstaller :) It sound quite simple. Thanks a lot, Christian ---------------------------------------- http://redmine.ruby-lang.org/issues/show/2750 ---------------------------------------- http://redmine.ruby-lang.org
