Hello- I'm working on making a simple test file that reproduces the problem, but in the mean time, does anyone recognize the following errors with Boost? I've narrowed it down to when I have #include for tf/tf.h, but I've used tf in the past with no problems. I suspect it might have something to do with the fact that my program is built in Qt, but like I said I am still trying to investigate. Anyway, I figured I'd throw it out there in case someone has already solved something like this. (Ubuntu 10.04 64-bit, cturtle all up-to-date as of today, Boost seems to claim it is 1.40) Thanks! --Adam In file included from /usr/include/boost/signals/connection.hpp:13, from /usr/include/boost/signals/signal_template.hpp:18, from /usr/include/boost/signals/signal0.hpp:24, from /usr/include/boost/signal.hpp:19, from /usr/include/boost/signals.hpp:9, from /opt/ros/cturtle/stacks/geometry/tf/include/tf/tf.h:45, from /home/aleeper/ros/cs324/users/aleeper/disney_executive/src/disney_gui.cpp:31: /usr/include/boost/signals/detail/signals_common.hpp:26: error: expected identifier before ‘protected’ /usr/include/boost/signals/detail/signals_common.hpp:26: error: expected unqualified-id before ‘protected’ /home/aleeper/ros/cs324/users/aleeper/disney_executive/src/disney_gui.cpp:472: error: expected ‘}’ at end of input make[3]: *** [CMakeFiles/exec.dir/src/disney_gui.o] Error 1 make[3]: Leaving directory `/home/aleeper/ros/cs324/users/aleeper/disney_executive/build' make[2]: *** [CMakeFiles/exec.dir/all] Error 2 make[2]: Leaving directory `/home/aleeper/ros/cs324/users/aleeper/disney_executive/build' make[1]: *** [all] Error 2 make[1]: Leaving directory `/home/aleeper/ros/cs324/users/aleeper/disney_executive/build' make: *** [all] Error 2 Adam Leeper Stanford University aleeper@stanford.edu 719.358.3804
