CentOS 5: make: g++: Command not found

You might see this error when attempting to install various packages or gems on CentOS Linux. I noticed it when attempting to install the ruby gem named eventmachine. After installing one RPM package via yum I no longer received the error when attempting to install the eventmachine gem.

EventMachine Gem Install Error Noticed:

[root@server]# gem install eventmachine

Gem files will remain installed in /usr/local/lib/ruby/gems/1.8/gems/eventmachine-0.12.0 for inspection.
Results logged to /usr/local/lib/ruby/gems/1.8/gems/eventmachine-0.12.0/ext/gem_make.out

Just install the gcc-c++ package via yum as shown below. After installing the gcc-c++ RPM package you should be able to now install the eventmachine gem without issue.

Install gcc-c++ Package Using Yum On CentOS Linux:
