Hi. Happy new year All !

system : ubuntu 18.04, running Melodic.

I followed :
git clone --recursive https://github.com/chvmp/champ git clone https://github.com/chvmp/champ_teleop cd .. rosdep install --from-paths src --ignore-src -r -y

then :
catkin_make

Compilation error :

I tried too, removing in https://github.com/chvmp/champ/blob/master/champ_gazebo/CMakeLists.txt#L5

Any idea ?

hi, have you resolved the issue?

[Auri]

This is due to the following line in champ_gazebo/CMakeLists.txt:

list(APPEND CMAKE_CXX_FLAGS "${GAZEBO_CXX_FLAGS}")

It appears that there is an extra semicolon being inserted here, modifying it to be as follows works:

add_compile_options("${GAZEBO_CXX_FLAGS}")
