Build errors when remote building ROS packages #26

Closed trackerpal closed 7 months ago

trackerpal commented 7 months ago

Hi, I am getting build errors when I try to build this package remotely from my VM. I'm trying to build the ROS packages remotely and send the executables to my RPi which runs them. I've tried installing the libcamera-dev onto my VM but the error still persists. 

CMake Error at /usr/share/cmake-3.22/Modules/FindPkgConfig.cmake:603 (message):

The CMake project is using pkg-config to search for libcamera. You can run pkg-config --modversion libcamera in the shell to check which libcamera version you have installed.

Which Linux distribution and version are you using to compile? And what is your target distribution and version on the Raspberry Pi? Are you trying to cross-compile or to compile on a virtualised arm machine? On Ubuntu 22.04, there is a binary package in the official ROS repository that you can install with sudo apt install ros-humble-libcamera.
