Hi.

Now that i have everything up and running on version 5.8 stable i found one last problem.

I can't compile the ant_track_pmm program found at paparazzi/sw/ground_segment/cockpit/

There is a chance that my ubuntu 14.04 LTS installation is a bit messed up so if you can't reproduce this error on other machines please let me know

The error i get is this:

address@hidden:~/paparazzi/sw/ground_segment/cockpit$ make

Now this means if i am not mistaken that the compiler cannot find the sqrt function

so i added  -lm to the linker flags.

This time i got this error:

address@hidden:~/paparazzi/sw/ground_segment/cockpit$ make
