    <p>I'm trying to compile the Sam Hare's <a href="http://www.samhare.net/research/struck/code">Struck code</a>.</p> <p>I'm using mac OSX10.9, opencv 2.4.6 and Eigen 2.0.17.</p> <p>Eigen and opencv headers are stored in /opt/local/include while opencv dylib in /opt/local/lib.</p> <p>I modified the Hare's Makefile to work on this folder. When I type make on the terminal:</p> <pre><code>g++ -L/opt/local/lib -lopencv_core -lopencv_highgui -lopencv_imgproc src/Config.o src/Features.o src/HaarFeature.o src/HaarFeatures.o src/HistogramFeatures.o src/ImageRep.o src/LaRank.o src/MultiFeatures.o src/RawFeatures.o src/Sampler.o src/Tracker.o src/main.o src/GraphUtils/GraphUtils.o -o struck </code></pre> <p>I get these errors:</p> <pre><code>Undefined symbols for architecture x86_64: "cv::namedWindow(std::__1::basic_string&lt;char, std::__1::char_traits&lt;char&gt;, std::__1::allocator&lt;char&gt; &gt; const&amp;, int)", referenced from: _main in main.o "cv::split(cv::Mat const&amp;, std::__1::vector&lt;cv::Mat, std::__1::allocator&lt;cv::Mat&gt; &gt;&amp;)", referenced from: ImageRep::ImageRep(cv::Mat const&amp;, bool, bool, bool) in ImageRep.o "cv::imread(std::__1::basic_string&lt;char, std::__1::char_traits&lt;char&gt;, std::__1::allocator&lt;char&gt; &gt; const&amp;, int)", referenced from: _main in main.o "cv::imshow(std::__1::basic_string&lt;char, std::__1::char_traits&lt;char&gt;, std::__1::allocator&lt;char&gt; &gt; const&amp;, cv::_InputArray const&amp;)", referenced from: LaRank::Debug() in LaRank.o Tracker::Debug() in Tracker.o _main in main.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) </code></pre> <p>Any ideas? Thanks!</p>

    1. COYou have a conflict between 32bit and 64bit libraries.

    3. COYou need to check all the libraries you linking together, whether they are 32 or 64 bits. I don't know how to do it if you are not sure where you get them.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
