  1. POErrors in Tesseract integration in iOS app
    text
    copied!<p>I am getting some errors while integrating Tesseract SDK in my iOS app. The procedure I have followed - </p> <p>1) Dragged "libtesseract_full.a" in xcode 2) Dragged "tessdata" folder in xcode 3) Dragged "baseapi.h" in xcode</p> <p>Now when I am using Tesseract - </p> <pre><code>// init the tesseract engine. tess = new TessBaseAPI(); tess-&gt;SimpleInit([dataPath cStringUsingEncoding:NSUTF8StringEncoding], // Path to tessdata-no ending /. "eng", // ISO 639-3 string or NULL. false); </code></pre> <p>I am getting these below errors (I think there is some framework or something like that missing, but not getting what is missing, tesseract demo project is working fine on my system)</p> <pre><code>clang: warning: argument unused during compilation: '-stdc++' ld: warning: CPU_SUBTYPE_ARM_ALL subtype is deprecated: /Users/saurabhsharma/Desktop/Tess/SnapXv2/libtesseract_full.a(libtesseract_full.o) Undefined symbols for architecture armv7: "std::basic_ostream&lt;char, std::char_traits&lt;char&gt;
