Hi, I downloaded opencv for windows from here - http://opencv.org/downloads.html

I did cmake. And then building with visual studio 2010. I get a build error in opencv_text

........\opencv_contrib\modules\text\src\ocr_beamsearch_decoder.cpp(569): error C2668: 'cv::sqrt' : ambiguous call to overloaded function

Is this a known problem.Have I got the wrong source? Or is there some compiler setting I should specify?.

hmm support for vs2010 seems to be fading ..

do the following:

cd (from cmdline) into opencv_contrib
make a new branch: git checkout -b text-sqrt-fix (you want the master branch to stay clean)
change line 569 to : patch_size = (int)sqrt((float)kernels.cols);
rebuild
eventually make a pull request

Oh I see. will do that.
