    <p>I would not even attempt to compile the OpenCV source code for an FPGA execution target. There are too many library dependencies and microprocessor architecture oriented assumptions in OpenCV (or in any large microprocessor targeted code base).</p> <p>There are compile-time and run-time libraries on any system. For one example, if we look at the run-time library dependencies of the OpenCV shared library, there are many microprocessor code libraries OpenCV itself uses:</p> <pre><code>dpointer@death:~$ ldd /usr/lib/libcv.so linux-vdso.so.1 =&gt; (0x00007fff1c1ff000) libcxcore.so.4 =&gt; /usr/lib/libcxcore.so.4 (0x00007f03279f7000) libavformat.so.52 =&gt; /usr/lib/libavformat.so.52 (0x00007f0327701000) libavcodec.so.52 =&gt; /usr/lib/libavcodec.so.52 (0x00007f0326ca7000) librt.so.1 =&gt; /lib/librt.so.1 (0x00007f0326a9f000) libz.so.1 =&gt; /lib/libz.so.1 (0x00007f0326888000) libdl.so.2 =&gt; /lib/libdl.so.2 (0x00007f0326683000) libstdc++.so.6 =&gt; /usr/lib/libstdc++.so.6 (0x00007f032636f000) libm.so.6 =&gt; /lib/libm.so.6 (0x00007f03260ec000) libgomp.so.1 =&gt; /usr/lib/libgomp.so.1 (0x00007f0325edd000) libpthread.so.0 =&gt; /lib/libpthread.so.0 (0x00007f0325cc0000) libc.so.6 =&gt; /lib/libc.so.6 (0x00007f032593a000) libgcc_s.so.1 =&gt; /lib/libgcc_s.so.1 (0x00007f0325722000) libavutil.so.49 =&gt; /usr/lib/libavutil.so.49 (0x00007f0325513000) libbz2.so.1.0 =&gt; /lib/libbz2.so.1.0 (0x00007f0325302000) libgsm.so.1 =&gt; /usr/lib/libgsm.so.1 (0x00007f03250f3000) libschroedinger-1.0.so.0 =&gt; /usr/lib/libschroedinger-1.0.so.0 (0x00007f0324e74000) libspeex.so.1 =&gt; /usr/lib/libspeex.so.1 (0x00007f0324c5a000) libtheora.so.0 =&gt; /usr/lib/libtheora.so.0 (0x00007f0324a0b000) libvorbisenc.so.2 =&gt; /usr/lib/libvorbisenc.so.2 (0x00007f0324630000) libvorbis.so.0 =&gt; /usr/lib/libvorbis.so.0 (0x00007f0324403000) /lib64/ld-linux-x86-64.so.2 (0x00007f03282f1000) liboil-0.3.so.0 =&gt; /usr/lib/liboil-0.3.so.0 (0x00007f0324172000) libogg.so.0 =&gt; /usr/lib/libogg.so.0 (0x00007f0323f6b000) dpointer@death:~$ </code></pre> <p>If you wanted to compile and use OpenCV on an FPGA system, you'd need to compile all of this library code for the FPGA, too. And you'd need an FPGA system run-time environment that would make sure these libraries on the FPGA were available when your code was running on the FPGA system. </p> <p>It's a huge task - you'd have to compile all the libraries OpenCV uses, all the libraries required by those libraries, OpenCV itself, and your top level application code. Oh, and write a run-time environment for your FPGA system. Even if you could compile all of that, it would not fit into an FPGAs resources.</p> <p>On the other hand, you could write your top level C code and any required image processing C code and compile that for an FPGA system. OpenCV source code is an outstanding reference tool for how to implement various image processing algorithms for FPGA targets. </p>

    1. COI see, thank you. However I did not really get the "Extracting...reasonable goal" part. It means I first compile normally on the computer, and then adjust my algorithms for the FPGA?

    2. CO@Chris - I mean you need to write image processing code instead of simply recompiling all of the OpenCV C code. I revised my answer to outline the complexity and magnitude of what I think you're proposing.

    3. CONow it's more clear, thanks again for the additional info. I will stick to simple C code.

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.
