I am trying to install gems from a local gem repository into Jruby 9.1.12.0 and I am getting stuck on Watir which is pretty much the first one I tried.
I am running on Windows 7 with JDK 1.8.0_131
I get the following:
Error installing watir:
ERROR: Failed to build gem native extension
it looks as though the rest of the error message is complaining about ffi-1.9.18 I am afraid I can't post the exact error message as it is inside a VM that is not internet enabled.
update: full error message:
C:\Ruby\gem>jruby -S gem install watir

I got this working now. It was obvious from the error message that 'Make' was not being located correctly. I added the correct directory to the path and Watir was installed correctly.
