[ros-users] [Discourse.ros.org] [OpenEmbedded] Catkin_make error building package on machine after image install

[Joe]

Hey all,

I am trying to build a package on the machine after I generated the image. I wanted to have it build with bitbake but had issues with external dependencies not building properly with BitBake so they have to be installed on the machine. 

catkin_make fails with error:
```
-- Using CATKIN_DEVEL_PREFIX: /home/root/lidar_workspace/devel
-- Using CMAKE_PREFIX_PATH: /opt/ros/indigo
-- This workspace overlays: /opt/ros/indigo
-- Using PYTHON_EXECUTABLE: /usr/bin/python
-- Using default Python package layout
-- Could NOT find PY_em (missing:  PY_EM) 
CMake Error at /opt/ros/indigo/share/catkin/cmake/empy.cmake:29 (message):

```
running `find tmp/sysroots/salvator-x/ -name "*empy*"` results in:
```

tmp/sysroots/salvator-x/pkgdata/runtime/python-empy
tmp/sysroots/salvator-x/pkgdata/runtime/python-empy.packaged
```
I'm sure I'm missing something important related to installing python-empy but from what I can see with the recipes it should be installed with the packagegroup-ros-comm. 

Any help is appreciated.
