vox_nav is not building , how to get this grid_map_cmake_heplers packgae ?

[BADAL244]

stderr: archived_vox_nav_grid_map
CMake Error at CMakeLists.txt:9 (find_package): By not providing "Findgrid_map_cmake_helpers.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "grid_map_cmake_helpers", but CMake did not find one.

Could not find a package configuration file provided by "grid_map_cmake_helpers" with any of the following names:

grid_map_cmake_helpersConfig.cmake
grid_map_cmake_helpers-config.cmake

Add the installation prefix of "grid_map_cmake_helpers" to CMAKE_PREFIX_PATH or set "grid_map_cmake_helpers_DIR" to a directory containing one of the above files. If "grid_map_cmake_helpers" provides a separate development package or SDK, be sure it has been installed.

Hello, Apologies for the late response. Currently, I am adding new features and haven't properly set up a flow to handle all dependencies.

You can get vox_nav itself and other core dependencies by vcstool.

Have a look at here. These are a bit outdated instructions but are good references on how to build vox_nav.

First get repos then build OMPL and Casadi;

mkdir -p ~/ros2_ws/src
cd ~/ros2_ws
source /opt/ros/foxy/setup.bash
wget https://raw.githubusercontent.com/jediofgever/vox_nav/foxy/underlay.repos
vcs import src < underlay.repos
rosdep install -y -r -q --from-paths src --ignore-src --rosdistro foxy
colcon build --symlink-install --cmake-args -DCMAKE_BUILD_TYPE=Release -DWITH_IPOPT=true --packages-select casadi ompl
sudo cp install/ompl/lib/libompl.so* /usr/local/lib/
sudo cp install/casadi/lib/libcasadi.so* /usr/local/lib/
sudo rm -rf src/ompl/
sudo rm -rf src/casadi/

Then build vox_nav itself;

source /opt/ros/foxy/setup.bash
cd ~/ros2_ws
colcon build --symlink-install --cmake-args -DCMAKE_BUILD_TYPE=Release --packages-skip-regex archived --packages-skip ompl casadi vox_nav_openvslam vox_nav_cupoch_experimental
source ~/ros2_ws/install/setup.bash

grid_map_cmake_helpers is an external dependency for an archived package of vox_nav, it is better not to build the archived packages as they are not in use.

Hopefully, you will be able to build vox_nav with the above command.

There is a robot model here, that you can use to test some features of vox_nav. You can send navigation commands to this robot with an RQT plugin, here you will find some guidance on how to do so, note I wrote these instructions some time ago, so things might look slightly different.

Feel free to comment if you are having trouble. Best,

Closing this for now but, Feel free to comment.
