Helo, I’m installing ruby-debug under cygwin for WinXP. Since i’m  
under cygwing I’m choosing ruby version (not win32). It starts  
installation but fails. The error is  
Gem::Installer::ExtensionBuildError  
Failed to build gem native extensions

ruby extconf.rb install ruby-debug  
creating Makefile

make  
sh: make: command not found

Does anyone know what it means?

cheers

You need to install the “make” package (in the Devel category) from  
cygwin  
setup.
