Jekyll quick start: Error installing jekyll, failed to build gem native extension

I’m looking at starting another blog at, as a home for my impractical chatbots. I thought I should check out a blog software other than WordPress, since all of my infosec colleagues make fun of me for using it. One option on my list is Jekyll, which builds static sites. That’s great if you are worried about resources (i.e. super-cheap hosting) and security.

The Jekyll site includes a 4-step quickstart. Unfortunately, it failed for me at step #1:

Error installing jekyll, failed to build gem native extension

I’m running this on a Fedora 27 virtual machine that I spun up for testing Jekyll:

$ cat /etc/system-release
Fedora release 27 (Twenty Seven)

My Ruby version is up-to-date:

$ ruby --version
ruby 2.4.3p205 (2017-12-14 revision 61247) [x86_64-linux]

Gem is installed and up-to-date:

$ gem --version

I took a closer look at the details of the error message:

gcc: error: /usr/lib/rpm/redhat/redhat-hardened-cc1: no such file or directory

I’m probably just missing a package, let’s see what package provides that file:

$ dnf provides redhat-hardened-cc1
Error: No Matches found

Fine, I let Google point me to a relevant StackOverflow post: G++ error:/usr/lib/rpm/redhat/redhat-hardened-cc1: No such file or directory

$ sudo dnf install redhat-rpm-config

I tried again:

$ sudo gem install bundler jekyll

It still failed, but with a different error:

make: g++: Command not found

I installed gcc-c++:

$ sudo dnf install gcc-c++

I tried to install Jekyll yet again:

$ sudo gem install bundler jekyll

That worked!

The following steps in Jekyll’s quickstart worked too:

$ jekyll new my-awesome-site
$ cd my-awesome-site
$ bundle exec jekyll serve

I copied my ~/my-awesome-site/_site folder to my document root (this can be automated with Jekyll, but I’m not there yet), and now, voila! my site is live:
