fatal error: proj_api.h: No such file or directory

[sayondeep]

From ubuntu 22.04 onwards libproj-dev >=8 does not come with proj_api.h hence causes the build to fail. Can you please help to resolve the issue?

Just try to install older version of this library.

Hii, thankyou for the reply .

great, can you share how so others can benefit from it.

My setup:
autoware on docker using latest cuda image (Ubuntu 22.04) with ROS2 humble.

Older version (<8) of libproj-dev cannot be installed on ubuntu 22.04.
Just procure the proj_api.h file from github repo of PROJ (branch 7.2 worked for me)
paste it in directory where the error occurs and change #include<proj_api.h> to #include"proj_api.h"

@hatem-darweesh I wanted some help regarding your setup.
In the tutorial you said you are using simulator on another machine.

1. I wanted to know on which machine is carla installed (only on other machine or both machine).
2. For op_bridge and op_agent CARLA_ROOT refers to directory on which machine?
