After Fixing One Charlock Issue I am getting another
/usr/local/rvm/gems/ruby-2.3.1/gems/charlock_holmes-0.7.3/lib/charlock_holmes/charlock_holmes.so: undefined symbol: _ZTIN6icu_488ByteSinkE

Centos 7
Ruby 2.3.1
Rails 4.2.5

I also see this problem and would really like to know what I need to do to fix it.
Fresh install of oxidized with -web on an ubuntu 16.04 system (also new). Oxidized works as expected. When setting rest: true, I see a very specific error related to charlock_holmes, which after a lot of looking seems to be related to icu4c, but I am not experienced enough to know for sure.

Here are a list of the installed gems on this system:

really I am just looking for a pointer that "you installed this wrong" or "this version isn't correct", as I am kinda at a loss at this point.

@jeremiahsherrill I think, at least in my case, this is related to icu4c, but I don't know for sure. Are you referencing icu4c with your application? From what I have read there could be issues with newer versions of icu4c and charlock_holmes, but again, I am not really a developer, so it's mostly piecing together other problem reports that have let me to that hypothesis.

[jeremiahsherrill]

I ended up having to remove it completely and just refactored what I was working on. Ultimately I am moving away from rails due to how many problems it has.

[buraglio]

I figured this out. I had to totally remove icu4c and charlock_holmes, then reinstall them from scratch. No idea what was going on, but it's working now.

Similar case here. I reinstall icu4c thru homebrew and issue resolved.
