When I run gem install iconv
, it fails as follows:
Building native extensions. This could take a while...

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.
I don't know how to fix this. What should I do?
