Hi All,
Good news… I think I've fixed this...
I decided to attempt to install “deface”on to our
pseudo-"production" foreman server:
[root@fman-vgrnt-01 vagrant]# *scl enable tfm "gem install deface"*
Fetching: polyglot-0.3.5.gem (100%)
Successfully installed polyglot-0.3.5
Fetching: colorize-0.8.1.gem (100%)
Successfully installed colorize-0.8.1
Fetching: mini_portile2-2.1.0.gem (100%)
Successfully installed mini_portile2-2.1.0
Fetching: nokogiri-1.6.8.1.gem (100%)
Building native extensions. This could take a while...
ERROR: Error installing deface:
ERROR: Failed to build gem native extension.
/opt/rh/rh-ruby22/root/usr/bin/ruby -r
./siteconf20161120-4146-wy5wdc.rb extconf.rb
mkmf.rb can't find header files for ruby at
/opt/rh/rh-ruby22/root/usr/share/include/ruby.h
extconf failed, exit code 1
Gem files will remain installed in
/opt/rh/rh-ruby22/root/usr/local/share/gems/gems/nokogiri-1.6.8.1 for
inspection.
Results logged to
/opt/rh/rh-ruby22/root/usr/local/lib64/gems/ruby/nokogiri-1.6.8.1/gem_make.out
So, obviously, I needed to install the relevant “devel” package for the
rh-ruby-22 software collection so that native extensions could be built. So
I ran this:
[root@fman-vgrnt-01 vagrant]# *yum install rh-ruby22-ruby-devel*
But I got the follow error:
http://mirror.centos.org/centos/6/sclo/x86_64/rh/repodata/repomd.xml:
[Errno 12] Timeout on
http://mirror.centos.org/centos/6/sclo/x86_64/rh/repodata/repomd.xml: (28,
'Connection time-out')
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository:
centos-sclo-rh. Please verify its path and try again
I tried again, and it worked, the centos repo mirror must have been having
a transient issue! I was then able to install deface and its dependencies:
[root@fman-vgrnt-01 vagrant]# *scl enable tfm "gem install deface"*
Building native extensions. This could take a while...

2 gems installed
So “deface” appears to be a run-time dependency required by plugins based
on the foreman plugin example template which, likely, need to be
incorporated into our foreman provisioning script.
I’m surprised none of the other plugins had the “deface” requirement.
Finally, after restarting apache, I was able to login to the foreman server
and see my plugin’s menu additions.
Now plugin development can start in earnest!
Cheers,
Doug
