The file mkmf.log is generated in the directory reported by gem install, "Gem files will remain installed in C:/Users/Deepak/Ruby192/ lib/ruby/gems/1.9.1/gems/ruby-serialport-0.7.0 for inspection." You need to look inside that folder and child folders for mkmf.log and look into its contents. -- Luis Lavena
