Компиляция AR Drone SDK завершается с отсутствием DSO из командной строки

Question

Я пытаюсь создать AR Drone SDK на Ubuntu. При компиляции библиотек я получаю ошибку:

//lib/x86_64-linux-gnu/libm.so.6: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

Я не понимаю, в чем проблема. Я следую this tutorial, и проблема возникает, когда я запускаю make. Я запустил ARDroneLib/Soft/Build/check_dependencies.sh, и он выводит нормально.

Любые идеи, в чем проблема? Ниже приведен полный вывод от запуска make.

У меня была та же проблема. Я нашел решение здесь:

http://jderobot.org/Varribas-tfm/ARDrone:starting_up#Building_Examples

Looking for undefined reference to symbol 'fabs@@GLIBC_2.2.5', I reached to [2], that confirms an unmeet dependency problem [1]. What happened here?

libavutil.a(eval.o): undefined reference to symbol 'fabs@@GLIBC_2.2.5' 
libm.so.6: error adding symbols: DSO missing from command line 

First line say us that libavutil is using fabs. It is declared into libm library, but -lm is missed in command line (Makefile).

ARDrone_SDK_2_0_1/Examples/Linux/Navigation/Build/Makefile:131 
GENERIC_LIBS+=-liw -lpc_ardrone -lgthread-2.0 -lgtk-x11-2.0 -lrt -lxml2 -ludev -lswscale -lSDL -lm 

Then, Navigation will compile successfully.
