<div dir="ltr">I thought that boost_python was the py2 binary, and boost_python3 was the py3 one?  Is this not a bug in caffe?</div><div class="gmail_extra"><br><div class="gmail_quote">On 13 March 2018 at 03:08, Jason Wessel <span dir="ltr">&lt;<a href="mailto:jason.wessel@windriver.com" target="_blank">jason.wessel@windriver.com</a>&gt;</span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">When using an image built with the Yocto Project which has a compiler<br>
and all the required libraries, projects such as caffe for the<br>
Movidius SDK which use python3 and boost fail to build because they<br>
look for libboost_python.so.  The error that cmake returns doesn&#39;t<br>
even point to the fact that this is why the configuration fails.<br>
<br>
Example showing the problem with the missing symlink:<br>
================<br>
  git clone <a href="https://github.com/weiliu89/caffe.git" rel="noreferrer" target="_blank">https://github.com/weiliu89/<wbr>caffe.git</a><br>
  cd caffe<br>
  mkdir build<br>
  cd build<br>
  cmake -DBLAS=Open ..<br>
<br>
-- Configuring done<br>
CMake Error at CMakeLists.txt:85 (add_dependencies):<br>
  The dependency target &quot;pycaffe&quot; of target &quot;pytest&quot; does not exist.<br>
================<br>
<br>
Conditionally creating the link when building python3 support into<br>
boost is all that is needed.<br>
