OpenSUSE: Getting to work the ruby script to login into dyndns.com automatically every week.

Posted by jpluimers on 2015/01/06

So I remember for the next time:

zypper install ruby
zypper install ruby-devel
zypper install gcc
zypper install gcc-c++

If you don’t install all these, them the gem will fail with errors like this:

ERROR: Failed to build gem native extension.
/usr/lib64/ruby/1.9.1/mkmf.rb:381:in `try_do': The compiler failed to generate an executable file. (RuntimeError)
You have to install development tools first.

What helps a lot for sorting out the above error messages is the Zypper Cheat Sheet (PDF).

But zypper was not enough as still it failed:

gem install mechanize

will eventually end with:

No such file or directory - getcwd

That was solved by running these two:

gem update
gem update --system

So I could install mechanize:

gem install mechanize
