Hello there!

I'm trying to run bebop_autonomy on a Raspberry Pi 3 with Raspbian Stretch (it has to be Raspbian, not Ubuntu) and ROS Kinetic. The problem is that the catkin version of the Parrot SDK provided by the autonomy lab won't compile:

In file included from /usr/include/endian.h:60:0,
                 from /usr/include/arm-linux-gnueabihf/sys/types.h:216,

After some research, the only solution I came across with was this: building the Parrot ARSDK libraries from source, adding tag TARGET_DEFAULT_ARM_MODE := arm in file SDK_folder/products/arsdk/native/config/product.mk, and building with:

 ./build.sh -p arsdk-native -t build-sdk -j

The SDK now compiles well but bebopautonomy does not find the library path, nor the parrotarsdk package.

The file product.mk is in 10 .tgz files in the parrotarsdk package (arsdk3_stripped.tgz). Modifying those files (adding the tag `TARGETDEFAULTARMMODE := arm`) does not resolve the problem.

Does someone know how to modify the bebopautomony's CMakeList to set the from-source-compiled parrotarsdk library path? Or how to modify the parrot_arsdk ROS package to compile in the RPi3?

Thanks
