I found old <ocl/Component.hp

includes. Thoses should not be related to
this but the number of errors decreased. And yes I am using Types.hpp quite
everywhere because of this in the release letter of 2.4:

We have confirmed reports of compilation time regressions when using GCC. We
are looking into reducing them. You can speed-up compilation times of
components by including the 'Types.hpp' files of the typekits you are using
in data ports, properties or operations. For example:

#include <rtt/typekit/Types.hp

// Speeds up compiling components
using regular C types

When I suppress this, I no more have some linking problems. So at least I am
no more stuck, thanks for this it was a real pain for my schedule.

It is a ROS build, I have rtt in "second" dependency, and I usually have
everything automatically added, but as I just switch to 2.4 so it is maybe
related.
Here are the few lines I add to my Cmake :
macro( add_orocos )
rosbuild_find_ros_package( rtt )
set( RTT_HINTS HINTS ${rtt_PACKAGE_PATH}/install )
find_package(OROCOS-RTT REQUIRED rtt-marshalling rtt-scripting
${RTT_HINTS})
include(${OROCOS-RTT_USE_FILE_PATH}/UseOROCOS-RTT.cmake)
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -DRTT_COMPONENT")
endmacro()
