Re: [OE-core] [PATCH 2/3] boost: Fix link problems with caffe and Movidius SDK

2018-03-14 Thread Jason Wessel 


I can't seem to find where cmake's python checker magically decides the name of 
the shared object, but I did find an override, so you can drop the patch.   I 
had even gone so far as to simply make a zero length file instead of the 
symlink, and everything still built and run.  It is just some cmake detection 
which is broken.  The ubuntu/debian systems where this code is heavily tested 
all provide a link for the libboost_python.so which explains why this never 
turned up previously.  They don't get the option to pick python2 or python3 for 
boost, they always get both for now.

The override to build with python boost for cmake and caffe is as follows:

cmake -DBoost_PYTHON_LIBRARY_DEBUG=/usr/lib64/libboost_python3.so \
   -DBoost_PYTHON_LIBRARY_RELEASE=/usr/lib64/libboost_python3.so \
   -DBLAS=Open \
   ..


Cheers,
Jason.

I used the path of least resistance because as far as I could tell boost only 
let you build one or the other and in my case it was the python3 boost api. In 
the end caffe was working and all the python3 tests with the Movidius SDK pass 
(which use python3).

Conditionally creating the link when building python3 support into
boost is all that is needed.

[OE-core] [PATCH 2/3] boost: Fix link problems with caffe and Movidius SDK

2018-03-12 Thread Jason Wessel 
When using an image built with the Yocto Project which has a compiler
and all the required libraries, projects such as caffe for the
Movidius SDK which use python3 and boost fail to build because they
look for libboost_python.so.  The error that cmake returns doesn't
even point to the fact that this is why the configuration fails.

Example showing the problem with the missing symlink:

  git clone https://github.com/weiliu89/caffe.git
  cd caffe
  mkdir build
  cd build
  cmake -DBLAS=Open ..

-- Configuring done
CMake Error at CMakeLists.txt:85 (add_dependencies):
  The dependency target "pycaffe" of target "pytest" does not exist.

boost is all that is needed.
