[ros-users] Integrating ROS node subscriber with X-Plane plugin

[Clayton Morrison]

Hi Josh,

More progress: following your suggestion of make clean/VERBOSE=1 make inside roscpp has definitely helped.  I found and reinstalled universal variants in port for boost and log4cxx, and I was able to manually rebuild xmlrpc as 32bit within it's 3rd party package.

The four remaining libs to rebuild are rospack, rosstack, roslib and rosconsole.  I have the following rosconfig.make file in <ROSROOT>:

	cmake_minimum_required(VERSION 2.4.6)
	set(ROS_COMPILE_FLAGS "${ROS_COMPILE_FLAGS} -arch i386")
	set(ROS_LINK_FLAGS "${ROS_LINK_FLAGS} -arch i386")

roslib and rosconsole seem to get the specified flags, but rospack and rosstack don't (I am doing make clean/VERBOSE=1 make in each individual package).  I even put rosconfig.make inside the rospack package root.

What do I need to do to get rospack and rosstack to see the -arch 1386 flags?

Thanks!

If you've followed the rest of the instructions for rosconfig.cmake (you'll probably want to create/edit $(ROS_ROOT)/rosconfig.cmake), you may just need to "rosmake --pre-clean <your package>"
