Hi Daniel,

thanks for the input!

Just did that. When I compile using g++ without ROS (or in my package
but without the roscpp dependency in place) it works, when I compile
it with the roscpp dependency it gets stuck within the futex after the
first gettimeofday().

The gettimeofday() call is not the one I try to execute in my code. My
gettimeofday() call is located after an output to the console, which
is not displayed, it gets stuck before it comes to echo something.

Probably I will set up a debugger on the gumstix and try to figure out
which in library and where the futex() and gettimeofday() calls are
made.

Thanks!
Sebastian
