12 years ago Ok so, about the require 'tesseract' it's somehow requiring the bin instead of the file in lib, so I guess it's ok it's failing.
About the require 'tesseract-ocr' I'd say the tesseract installed through ports either misses the headers or misses the strngs.h header, find out where it installed the headers and if they're all present.

Hey there, I'm really grateful that you've put together this gem. I'm looking to do some OCR work for a grad school project and would love to be working in Ruby and Tesseract seems like the right OCR library to be working with.
So far I'm having a hard time getting up and running though. Below are the crashes that happen when I try to include 'tesseract or 'tesseract-ocr' in IRB. Could you take a look at what I'm doing and see if there's anything apparently wrong?
FYI things I know/am running
When I try to include Tesseract in a IRB it throws the follow error:
And when I require Tesseract-OCR I get this error:
The results of that log look like:
I believe I've correctly pulled down your version of ffi-inline and installed it but that could be the sticking point. I also noticed that a few commits back you changed the gemspec to no longer require ffi-inliner but ffi-inline instead yet in the c.rb file it's using ffi-inliner. I'm kind of a newb so maybe that isn't the problem.
Any thoughts?
