From: Dd Dd Date: 2010-10-26T07:30:07+09:00 Subject: Can't get ruby serial port to work I recently installed Ruby Version 1.9.2 on my PC. I am trying to get the serial port to work. On the command prompt, I typed "gem install ruby-serialport", but it didn't go through. I attached the file of the whole response from the command prompt. Here are the first few lines: C:\Users\Deepak>gem install ruby-serialport Building native extensions. This could take a while... ERROR: Error installing ruby-serialport: ERROR: Failed to build gem native extension. What could be the problem? Do I need to add a file to the library? Thanks.
