Hi @luna wu

Have you installed dependencies as per repo instructions?:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo add-apt-repository ppa:inivation-ppa/inivation-bionic
sudo apt-get update
sudo apt-get install dv-gui

Yes, I have installed the codes you listed. But there was still the same error.

I really want to know why it has been installed successfully, but it still shows no ``libcaer''. How should I solve this problem?

Thanks.

Can you pls share CMakelists.txt?

Here is the CMakelist.txt

cmake_minimum_required(VERSION 2.8.3)
project(davis_ros_driver)

find_package(catkin_simple REQUIRED)
find_package(libcaer REQUIRED)

catkin_simple()

SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -O3")

find_package(Boost REQUIRED COMPONENTS system thread)

# make the executable
cs_add_executable(davis_ros_driver
  src/driver_node.cpp
  src/driver.cpp
)

# make the nodelet into a library
cs_add_library(davis_ros_driver_nodelet
  src/driver_nodelet.cpp
  src/driver.cpp
)

# link the executable to the necesarry libs
target_link_libraries(davis_ros_driver
  ${catkin_LIBRARIES}
  ${Boost_LIBRARIES}
  libcaer::caer
)

# link the executable to the necesarry libs
target_link_libraries(davis_ros_driver_nodelet
  ${catkin_LIBRARIES}
  ${Boost_LIBRARIES}
  libcaer::caer
)

# Install the nodelet library
cs_install()

# Install other support files for installation
install(FILES davis_ros_driver_nodelet.xml
  DESTINATION ${CATKIN_PACKAGE_SHARE_DESTINATION}
)

Searching for the error message, this is what I found: https://github.com/uzh-rpg/rpg_dvs_ro...

If you look at the instructions, catkin_simple is used not catkin buildhttps://github.com/uzh-rpg/rpg_dvs_ros

Clone the catkin_simple package (https://github.com/catkin/catkin_simple), which will be used to build the DVS/DAVIS driver packages:

$ cd ~/catkin_ws/src
$ git clone https://github.com/catkin/catkin_simple.git

Clone this repository:

$ cd ~/catkin_ws/src
$ git clone https://github.com/uzh-rpg/rpg_dvs_ros.git
Build the packages:
$ catkin build dvs_ros_driver (if you are using the DVS128)
$ catkin build davis_ros_driver (if you are using the DAVIS)
$ catkin build dvxplorer_ros_driver (if you are using the DVXplorer)

What installation instructions are you following?

Thanks again

I used https://github.com/uzh-rpg/rpg_dvs_ros, and followed the above steps exactly (I have replaced kinetic with melodic)

I have run it many times， but there was still the same error.

I was able to reproduce the same error. I will work on it, to see how. I couldn't install libcaer from apt though.

It's a pity。I have posted an issue at https://github.com/uzh-rpg/rpg_dvs_ro... but no one has responded yet。
