Gem files will remain installed in /usr/local/share/gems/gems/charlock_holmes-0.6.9.4 for inspection.

I already installed libicu-devel.

Thanks

Answer 1

I had the exact same issue today. Tried to install gitlab on a clean fedora machine. For me, a line in /usr/local/share/gems/gems/charlock_holmes-0.6.9.4/ext/charlock_holmes/gem_make.out pointed to mkmf.log, which is in the same directory as above log file.

There it said "patch: command not found"

sudo yum install patch

Answer 2

In you output I can read:

extconf.rb:7:in `sys': patch -p0 < ../file-soft-check.patch failed, please report issue on http://github.com/brianmario/charlock_holmes (RuntimeError)

So it all points to a bug. I suppose it is a good idea follow the output and created an issue there, explaining what you are trying to do and giving details of your environment.

ruby-devel is missing

yum install ruby-devel

and you'll be set :)
