Hi there, This launch config works for my use case (Raspberry Pi 4 - ROS2 Galactic - run node as root with access to GP

Hi, I have exactly the same problem. I have prepared a URDF file that works perfectly in ROS melodic, but it does not ge

you can also try to set as a C/CXX compiler gcc-5 using:

export CC=/usr/bin/gcc-5 export CXX=/usr/bin/g++-5

and then compile again using catkin_make

Hi! you can try adding to CMakeList.txt:

pkg_search_module(Eigen3 REQUIRED eigen3)
include_directories(${EIGEN3_INCLUDE_DIR})
add_definitions(${EIGEN3_DEFINITIONS})

if(NOT EIGEN3_FOUND)
    # Fallback to cmake_modules
    find_package(cmake_modules REQUIRED)
    find_package(Eigen REQUIRED)
    set(EIGEN3_INCLUDE_DIRS ${EIGEN_INCLUDE_DIRS})
    set(EIGEN3_LIBRARIES ${EIGEN_LIBRARIES})  # Not strictly necessary as Eigen is head only
    # Possibly map additional variables to the EIGEN3_ prefix.
else()
    set(EIGEN3_INCLUDE_DIRS ${EIGEN3_INCLUDE_DIR})
endif()

catkin_package(
    ...
    DEPENDS Eigen
    ...
)

include_directories(
    ...
    ${Eigen_INCLUDE_DIRS}
)

This setup works for me, I also got problems before with Eigen.

I hope it helps you.

Hi! You can try: download the cv_bridge source folder from https://github.com/ros-perception/vis... and paste it into the src folder of your workspace and then try to compile it again.

Hi! The easiest way for me is to make a copy (ISO image) of your MicroSD and then put it in the MicroSD of the new Raspberry. It can guaranteed that everything will work properly.

@dirk-thomas I have upgraded ubuntu from 14.04 to 16.04, install ROS kinetic, I tested the nodes without compiling (OK), then I have compiled and installed OpenCV 3.1, for that, I change the GCC version from 5.3 to 4.8 and after that catkin_make fails. I didn't try it before change GCC version : (

I finally solve the problem changing the compiler from gcc-5 to clang. It is not an optimal solution but it works for me:

Ubuntu 14.04 have GCC-4.X and in ubuntu 16.04 the default version is GCC-5.X. first, I try to change the default version using "sudo update-alternatives --config gcc" and selecting GCC-4.8 but it doesn't work for me.

So, simply I add this lines to CMakeLists.txt

set(CMAKE_CXX_COMPILER "clang++")

set(CMAKE_C_COMPILER "clang")

if you need to install clang in ubuntu 16.04: sudo apt-get install clang

I hope It helps you.

I also got the same problem after updating my ubuntu from 14.04 to 16.04 : ( catkin_make doesn't link ROS libraries!
