Hi guys, Ive been trying to install the gem, ruby-serialport but having troubles with it on windows. I have installed the Devkit but no luck with installing the serialport. I have seen a few people having similar problems but haven't found a solution. C:\Ruby192\bin>gem install ruby-serialport Temporarily enhancing PATH to include DevKit... Building native extensions. This could take a while... ERROR: Error installing ruby-serialport: ERROR: Failed to build gem native extension. C:/Ruby192/bin/ruby.exe extconf.rb checking for OS... mingw checking for termios.h... no *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options. Provided configuration options: --with-opt-dir --without-opt-dir --with-opt-include --without-opt-include=${opt-dir}/include --with-opt-lib --without-opt-lib=${opt-dir}/lib --with-make-prog --without-make-prog --srcdir=. --curdir --ruby=C:/Ruby192/bin/ruby Gem files will remain installed in C:/Ruby192/lib/ruby/gems/1.9.1/gems/ruby-serialport-0.7.0 for inspection. Results logged to C:/Ruby192/lib/ruby/gems/1.9.1/gems/ruby-serialport-0.7.0/ext/gem_make.out Help will be much appreciated!! Thanks -- Posted via http://www.ruby-forum.com/.
