Hi,

I try to get the ofxTesseract addon work with of_v0.9.8_osx but I get Mach-O-Linker errors. Anyone had the same issue? Running Xcode 8.2.1, MacOS Sierra. I used the ProjectGenerator generate the project and add the Add-on to my project.

Got it from github here and moved it to the add-on folder.

Error I got
Undefined symbols for architecture x86_64:

Got this in my ofApp.cpp
void ofApp::setup(){
ocr.setup();
ocr.setWhitelist("0123456789");
ocr.setAccuracy(ofxTesseract::ACCURATE);
img.loadImage("article.png");
string result = ocr.findText(img);
cout << result << endl;
}

ofApp.h
#include "ofxTesseract.h"

and this, besides the empty example code:
ofxTesseract ocr;
string tessStr;
ofImage img;

I am new to OF no idea how I could fix this. Would really appreciate a hint in the right direction. Thanks a lot!
